Preface
Third Edition
The Second Edition of the Applied Tribology was published nearly a decade ago. Since then,
the book has been adopted for courses in many universities as has served as the basis for many
short courses and lectures in industries. With great appreciation to many positive comments
received, the Third Edition has expanded chapters on micro-contact of surface asperities, fric-
tion and wear, thermal effect, and elastohydrodynamic and mixed lubrication. Nearly all chap-
ters have been revised with expanded sections, updates with an emphasis on new research and
development, and many additional references. As in the previous editions, we strive to maintain
a balance between application and theory. Each chapter contains numerous example problems
to illustrate how different concepts can be applied in practice. We hope that this book can serve
the need for a single resource for a senior elective or a graduate-level course in tribology and
a reference book for practicing engineers in the industry.
This edition would not have been possible without the inspiring research and assistance of
numerous colleagues and former students associated with the Center for Rotating Machinery
at Louisiana State University. In particular, we gratefully acknowledge the feedback by Drs.
J. Jang, S. Akbarzadeh, X. Lu, J. Wang, W. Jun, Z. Luan, M. Mansouri, K. ElKholy, Z. Peng,

Preface
Second Edition
Tribology is a diverse field of science involving lubrication, friction, and wear. In addition to
covering tribology as involved in bearings, the same basic principles are also demonstrated
here for other machine elements such as piston rings, magnetic disk drives, viscous pumps,
seals, hydraulic lifts, and wet clutches.
In this second edition of Applied Tribology all the chapters were updated to reflect recent
developments in the field. In addition, this edition contains two new chapters: one on the fun-
damentals of seals and the other on monitoring machine behavior and lubricants, as well as
bearing failure analysis. These topics are of considerable interest to the industry practitioners
as well as students and should satisfy the needs of the tribology community at large.
Computer solutions for basic fluid film and energy relations from the first edition have been
extended to seal performance. New developments in foil bearings are reviewed. For ball and
roller bearings, conditions enabling infinite fatigue life are covered along with new ASME and
bearing company life and friction factors.
Properties of both mineral and synthetic oils and greases are supplemented by an update
on the greatly extended service life with new Group II and Group III severely hydrocracked
mineral oils. Similar property and performance factors are given for full-film bearing alloys,
for dry and partially lubricated bearings, and for fatigue-resistant materials for rolling element
bearings. Gas properties and performance relations are also covered in a chapter on gas bear-
ing applications for high-speed machines and for flying heads in computer read–write units
operating in the nanotribology range.
Problems at the close of each chapter aid in adapting the book as a text for university and
industrial courses. Many of these problems provide guidelines for solution of current design
and application questions. Comprehensive lists of references have been brought up to date with
145 new entries for use in pursuing subjects to greater depth.
Both SI and traditional British inch-pound-second units are employed. Units in most com-
mon use are generally chosen for each section: international SI units for ball and roller bearing
dimensions and for scientific and aerospace illustrations, traditional British units for oil-film
bearings in industrial machinery. Many analyses are cast in dimensionless terms, enabling use
of either system of units. Conversion factors are tabulated in two appendices, and guidelines
for applying either system of units are given throughout the book.
The authors are indebted to past coworkers and students for their participation in developing
topics and concepts presented in this book. Comprehensive background information has been
xiv Preface
assembled by the authors from their combined 80 years of laboratory, industrial, teaching, and
consulting experience. Much of this background has been drawn from well over 250 technical
publications, most of them in archival literature. Theses and dissertation projects at Ohio State
University, the University of Pittsburgh, Southern Illinois University, Louisiana State Univer-
sity; and the Pennsylvania State University; numerous industrial projects at the Center for
Rotating Machinery at Louisiana State University; four tribology handbooks organized and
edited for the Society of Tribologists and Lubrication Engineers; and a 1957 book Bearing
Design and Application coauthored with D. F. Wilcock.
This book is intended (1) for academic use in a one-semester senior engineering elec-
tive course, (2) for a graduate-level course in engineering tribology and (3) as a reference
book for practicing engineers and machine designers. It is hoped that these uses will provide
paths for effectively designing, applying, and lubricating bearings and other machine elements
while taking advantage of concepts in tribology—the developing science of friction, wear, and
lubrication.

walked the air, the dead did not sleep well nights, but were ever
getting up out of their graves and returning to their old places
to warn the living. The spirit-world of darkness was an ever-
present reality, a nightly terror, and there were no angel chariots
in the clouds, nor angel feet in the ways of sorrow and death.
New England was a goblin-land. Going to bed in some distant
chamber in an old oak house was a specially perilous journey
for the young Puritan to make; one could never tell whether
one’s dead grandfather was in his grave at that hour or not.
Young folks with disturbed consciences went to bed with
alacrity, and drew the sheets over their heads quickly, in Cotton
Mather’s day.
The Mount Hope lands! How beautiful they were and are! But
the old houses on them were filled with dark superstitions. This
is not strange, for the Mount Hope lands had been the fields of
great events. Few places in America had such a romantic
history.
JAPANESE HO-O-DEN.
Leif Ericson, Massasoit, John Hampden, Roger Williams,
Washington—what an array of great names and noble
associations! We may well claim that there are few spots on
American soil which are so grand in historic events of a highly
poetic coloring as the old Mount Hope lands. As to lesser men,
we have not space for more than an allusion: Church, the
Indian-fighter, of cruel memory, the heroes of the “Gaspee,” and
the old privateers. Lafayette was quartered here, and General
Burnside here made his home on the borders of the beautiful
hills after the Union war. In the prosperous colonial years before
the Revolution there came to live on the Mount Hope lands in
summer some grand families whom the world has almost
forgotten. Among them were the Vassals of Boston, and the
Royalls, also rich Boston people, whose home was at the Mount.
These people were royalists, and fled from the country at the
beginning of the war, and their estates were confiscated. The
Mount Hope farm of the Royalls was among the confiscated
estates. These people fled to the Windward Islands. The old
Vassal tomb may still be seen in Cambridge churchyard,
Massachusetts, near Harvard College. Of course the confiscated
estate of the Royalls became haunted after the flight of its
stately owners. The white ghost of Penelope Royall is supposed
never to have left the romantic farms, but to have remained to
terrify whomsoever might live upon these enchanted regions of
the rightful territories of good King George. In her happy days
this queenly woman used to ride in her high chariot through
Bristol, greatly to the admiration of the Wardwells, the
Bosworths, the Gladdings, the Churches, the Byfields, and the
well-to-do townspeople of the cool old port. The white sail that
bore the Royalls drifted over the tropic seas, but not in
imagination the ghostly form and robes of Penelope Royall.
They stayed to affright the rebels, and to uphold the rights and
the dignities of the Crown. All disloyal Bristol could not arrest
the spirit of Penelope, which seems to have delighted in the
freedom denied to the royalists in the flesh. She was a maiden
lady, and a more stately person than either Anna or Priscilla
Royall, the old royalist’s first and second wives. She loved the
Mount Hope lands, and especially Mount Hope, and used often
to visit the white ridge overlooking the bays, and gaze over the
glittering waterways and the green expanse of Rhode Island,
where Bishop Berkeley is said to have made his immortal
prophecy. She died in the old house, and was buried near it.
It was near the close of the last century that Prudence
Wardwell, a rich spinster, came to live on the old Royall farm on
the Mount Hope lands. The house which she occupied was
noted for its great chimney. All the old Bristol houses had
enormous chimneys with great fireplaces. One of these
chimneys, it has been said, would furnish sufficient material to
build a modern cottage. Several of them once stood like
monuments, after the houses they had warmed were gone; and
cattle, in the winter, would sometimes find a shelter in their
giant fireplaces.
Prudence Wardwell—“Aunt Prudence,” as she was known—
brought to the great oak mansion a bound boy by the name of
Peter Fayerweather. It had been her wish to live as nearly alone
as possible, with but a single protector, and for this solitary
guardian and sentinel she had chosen Peter. He was a tall,
awkward lad, with great eyes and a shambling gait; but Aunt
Prudence believed him to be honest, and she did not want a
“handsome man” on the place. Peter was not handsome. Peter
had objected to going to the Mount on account of the ghost folk
there. His large eyes and large ears seemed to grow as he
listened to the old tales of superstition. He had heard again and
again with terror the awful tale of Captain Kidd: how that
recreant son of the old Scottish minister and martyr had gone
forth on the high seas to destroy pirates, and had turned pirate
himself; how he had sunk his good father’s Bible “in the sand,”
and had murdered William Moore, “as he sailed, as he sailed.”
The Mount Hope lands were full of Indian stories, which were
founded on tricks, and even worse stories of those whose wits
cheated the devil out of his dues, when their grasping souls had
bargained with the latter. Peter thought of these. There was one
story that suggested to him that wit is equal to most conditions
of life. It was a red settle story, but became a poem:—
“Among Rhode Island’s early sons
Was one whose orchards fair
By plenteous and well-flavored fruit,
Rewarded all his care.
“For household use they stored the best,
And all the rest, conveyed
To neighboring mill, were ground and pressed
And into cider made.
“The wandering Indian oft partook
The generous farmer’s cheer;
He liked his food, but better still
His cider fine and clear.
“And as he quaffed the pleasant draught
The kitchen fire before,
He longed for some to carry home,
And asked for more and more.
“The farmer saw a basket new,
Beside the Indian bold,
And smiling said, ‘I’ll give to you
As much as that will hold.’
“Both laughed, for how could liquid thing
Within a basket stay?
But yet, the jest unanswering,
The Indian went his way.
“When next from rest the farmers sprung
So very cold the morn,
The icicles like diamonds hung
On every eping and thorn.
“The brook that babbled by his door
Was deep, and clear, and strong,
And yet unfettered by the frost,
Leaped merrily along.
“The self-same Indian by this brook
The astonished farmer sees;
He laid his basket in the stream,
Then hung it up to freeze.
“And by this process oft renewed,
The basket soon became
A well-glazed vessel, tight and good,
Of most capacious frame.
“The door he entered speedily,
And claimed the promised boon;
The farmer laughed heartily,
Fulfilled his promise soon.
“Up to the basket’s brim he saw
The sparkling cider rise,
And to rejoice his absent squaw,
He bore away the prize.
“Long lived the good man at the farm,
The house is standing still,
And still leaps merrily along
The much diminished rill.
“And his descendants still remain,
And tell to those who ask it,
The story they have often heard
About the Indian’s basket.”
A wonderful reformation seemed to come over Peter. He
began to stay at home, and go to bed very early, often as early
as seven o’clock,—or at least he seemed to do these sober
things. Aunt Prudence had gone to the door of his room once or
twice after his early retiring, but had found it locked, and she
had been unable to awake him, he “slept so sound.” “Boys do,”
she said.
“Peter,” she said one morning, “tell me the truth, now; didn’t
you hear me when I pounded and pounded on the door last
night?”
“No, Aunt Prudence, true as preachin’ I did not.” And he did
not.
The truth was that poor Peter had fallen from his integrity,
even in these times of the great revivals. He had discovered that
the great hall window was as handy as a door, and that he had
only to leave it unfastened to return to the house at any time of
the night without disturbing the sound slumbers of good Aunt
Prudence. He was careful in taking this liberty to first lock his
own room. These were wicked ways, it is true, and very bold
ones for a quiet youth, and quite inconsistent with meeting-
going habits. But the meetings at this period were wonderfully
dramatic; everybody talked about them, and Peter’s curiosity
quite overcame his moral sense.
The holidays were at hand. Thanksgiving was Aunt Prudence’s
great annual festival, her Feast of Tabernacles; she made little
account of Christmas, which, she told Peter, was a mere “relic of
the Pope and the Dragon,” and which he associated with an old
picture in the “Pilgrim’s Progress.”
Watch Night was the great annual occasion of the old Bristol
Methodists. It took place on New Year’s Eve, when a great
assembly used to meet to sing the old Wesleyan Watch Night
hymns, written by Wesley for the Old London Foundry, and to
watch “the old year out and the new year in.” The services of
the Presiding Elder were sometimes secured for this memorable
night, and if so, a “Love Feast” was held, and a multitude told
their experiences, amid triumphant responses, ecstatic refrains,
and sometimes strange exhibitions of trance, or of “losing one’s
strength,” as the old phenomena were called.
Christmas was the Episcopal festival, and the Episcopal
Church in Bristol was unlike any other at that time. It followed
the revival methods of Whitefield and Lady Huntingdon.
Christmas Eve was an occasion of universal charity. The poor
were the guests of the church, and were entertained like
princes. Peter well understood all these festivals, and he
resolved to attend them all,—the old Orthodox church’s
Thanksgiving, the Episcopal festival, and the Methodists’ solemn
jubilee on New Year’s Eve. There was nothing sectarian about
him. It was also his intention not to disturb the mind of Aunt
Prudence about these matters,—the easy hall window would
make it unnecessary.
CITY HALL.
The hall was empty; all was still. The grim old portraits were
there—like shadow people they were all.
She left the sitting-room door open, and moved silently and
cautiously along toward Peter’s room. She tried Peter’s door. A
great sense of relief came to her; it was unlocked. She opened
it slowly, but a draught blew out the light. Terrified at this, she
glided to Peter’s bed and seized the boy by the hair, gasping,
“Peter, Peter, there’s a man in the house! Get up, get up! there’s
a man in the house!” She shook him with a nervous energy, and
repeated in stage-like whispers the words. She then vanished
out of the room.
Peter awoke at the first touch of the rude hand, and his heart
seemed to stop, and his blood to turn to frozen streams, as he
saw an awful white spectre standing over his bed, and felt its
bony fingers in his hair. Penelope flashed upon him. It surely
was the ghost of Penelope; she had got away from the other
world this time, surely, despite his reason and philosophy. He
looked around wildly, saw the shadow of the old ox-saddle that
adorned this room as a curiosity,—and Penelope, awful
Penelope.
Penelope’s final shake of his great shoulders nearly put a
period to his unromantic history. A chill like death came over
him, and he fully believed that his last moments had come. The
gasped words, “There’s a man in the house—get up!” were
something of a relief. “A man!” If he would only appear! Then
he beheld the unearthly white figure vanish through the door. It
surely was Penelope. She had gone; and oh, if the man, if any
man, would come!
He lay petrified for a moment, and then thought of the old
smoke chamber. His decision was immediate. He leaped up,
drew the dark patchwork coverlid around him, and darted
upstairs. Past loom, hatchel, and spinning-wheel, he made his
way to the iron door, leaped into the smoke chamber, closed the
door behind him, and sank down in a heap, with a most decided
resolution to leave the house in the morning forever, “true as
preachin’.” He drew the industrial coverlid around him, leaving
only an opening for his eyes.
Aunt Prudence went back to her room, and locked the door
tremblingly, and waited for Peter’s step. But no Peter came. Her
suspense grew unbearable again. Suddenly she too thought of
the old smoke chamber, and drawing her ghostly robe again
around her, she went into the hall, and silently and very
cautiously made her dark way up the stairs. She too, past loom,
hatchel, and spinning-wheel, found her way to the iron door,
and pulling it open, prepared to enter the dark grated chamber.
If ever a mind was supped full of horror, it was Peter’s when
he heard a noise at the iron door, and beheld the supposed
ghost of Penelope Royall, tall and avengeful, standing before
him. He uttered a pitiful shriek, slid through the iron bars, and
dropped down the chimney into the fireplace. There he
