INTRODUCTION

TAKING THE INITIATIVE

In today’s demanding industrial environment, specialist
technology is, more than ever, key to improved efficiency,
productivity and ultimately profitability. Timken is increasingly
seen as a product brand, that routinely challenges technological
boundaries.
Rapid response and flexibility result from a production facility
manufacturing not only split cylindrical roller bearing assemblies
but also cutting edge products for aerospace and railway. The
unique relationship between manufacturer and distributors
combined with innovative cellular manufacturing and modular
stocking offer unparalleled availability.
From concept to design, design to production, and then throughout
the life cycle of the unit, no other split bearing manufacturer works
so hard to exceed your expectations.

INNOVATION IN SERVICE accommodating split options.
Producing products that push the boundaries of performance is
only the beginning. Timken recognizes that users and specifiers
of split cylindrical roller bearings demand logistical, technical
and after-sales support.
Experienced application engineering support assists customers
with concepts through consultation, commissioning, training,
supply and post installation support.
Regional inventory provides excellent availability of product in
the right place at the right time.

in even higher potential savings.

INSPECTION SIMPLIFIED
No matter what the size or type of split cylindrical roller bearing,
inspection is straightforward. Simply remove the support cap and
the top half of the housing and all bearing parts become visible
and accessible.

SHORT TERM PAYBACK, LONG TERM

BENEFITS
Though it would be easy to cite examples where the use of split
bearings results in spectacular savings, significant savings can
be seen in almost any trapped application. Even modest savings
can be enough to justify the use of split bearings. Depending
on the application, down times for replacement of
split bearings can be a small fraction of those
required for solid bearings. This yields
savings in both maintenance work-
hours and lost production.
When such cost savings are
taken into account at the
bearing selection stage,
it's easy to make the case
for choosing Timken split
cylindrical roller bearings.

HOW TO USE THIS CATALOG

HOW TO USE THIS CATALOG

We designed this catalog to help you find the Timken bearings
best suited to your equipment needs and specifications.
The product tables list mounted split bearings and components.
For other bearing types, please refer to the respective Timken
product catalog reference.
Timken offers an extensive range of bearings and accessories
in both imperial and metric sizes. For your convenience, size
ranges are indicated in millimeters and inches. Contact your
Timken engineer to learn more about our complete line for
the special needs of your application.
This publication contains dimensions, tolerances and
load ratings, as well as engineering sections describing
mounting and fitting practices for shafts and housings,
internal clearances, materials and other bearing features.
It provides valuable assistance in the initial consideration
of the type and characteristics of the bearings that may
best suit your particular needs.
ISO and ANSI/ABMA, as used in this publication, refer to the
International Organization for Standardization and the American
National Standards Institute/American Bearing Manufacturers
Association.

SHELF LIFE
Shelf life should be distinguished from lubricated bearing/
component design life as follows:
• Shelf life of the grease-lubricated bearing/component
represents the period of time prior to use or installation.
• The shelf life is a portion of the anticipated aggregate design
life. It is impossible to accurately predict design life due to
variations in lubricant bleed rates, oil migration, operating
conditions, installation conditions, temperature, humidity
and extended storage.
• Shelf life values, available from Timken, represent a
maximum limit and assume adherence to the storage
and handling guidelines suggested in this catalog or
by a Timken associate. Deviation from the Timken
storage and handling guidelines may reduce shelf
life. Any specification or operating practice that
defines a shorter shelf life should be used.
Timken cannot anticipate the performance of the grease
lubricant after the bearing or component is installed or
placed in service.
TIMKEN IS NOT RESPONSIBLE FOR THE SHELF LIFE
OF ANY BEARING/COMPONENT LUBRICATED BY

specialized applications.

PILLOW BLOCK (SUPPORT) TYPE

This is by far the most popular method for mounting Timken units.
These supports are manufactured from high strength, ASTM
48A grade 35 cast iron. This, combined with the robust design,
provides a stable, rigid base, allowing the split bearing fitted to
give optimum performance.

TAKE-UP UNITS
These sliding units can be used to effectively tension conveyor

FLANGE UNITS
In applications where bearings need to be mounted against
horizontal or vertical faces, Timken flange units provide a simple
means of achieving this goal. Again, the use of ASTM 48A Grade

SERIES COMPARISON
Timken offers a range of bearing series, providing solutions
for a wide range of operating conditions. Light Series,
Medium Series and Heavy Series offer an increasing ability to
accommodate higher loads. As the series increases the speed
capability reduces.

Light Series
The most commonly applied series offering good
load and speed capabilities with the smallest
section within the range.

Heavy Series
A more specialized series used in the most heavily loaded
applications, generally operating at relatively low speed.

Medium Series
An increased section offers additional load carrying capacity.
This series is typically used in difficult, heavily loaded applications
where shock load and vibration may be present.

Cleanliness of component parts when fitting will have a direct

particular importance when fitting new bearings into existing cast

iron or refitting bearings after maintenance. Special care must be
taken to remove build-ups of aged grease and other contaminants
in order to avoid reducing the bearing clearance when fitted.
When selecting bearings for use at elevated temperatures, 120° Cor
consideration also should be given to the bearings' dimensional
stability. Timken bearings are tempered to give stability up to
140° C (284° F). In order to operate at higher temperatures,
bearings must be specially heat-treated. This process will lead
to a reduction in capacity as a result of the reduced hardness.
The designations for specially heat-treated bearings are in line
with those quoted in ISO standards. The effects of temperature
stabilization are detailed in the table shown.

MEDIUM SERIES

Medium series bearing products can be utilized in

applications requiring higher load-carrying capacity. Under
normal conditions, medium series also may be selected to
provide an extended bearing life when compared to light series.
Medium series offers the same range of mounting and sealing
solutions as light series, with the exception of hanger units. If
a standard catalog product does not meet your requirements,
a Timken engineer will be happy to provide help and advice on
your application.

SAF/SN/SD BEARINGS

SAF/SN/SD BEARINGS
The new compact split plummer block bearing
from Timken is the first split cylindrical roller bearing
assembly to be interchangeable with standard SAF, SN and
SD series plummer blocks, bringing the benefits of a split design to
a much wider customer base.
