Basic designations:
• The irst igure or the irst letter or combination of letters identiies the bearing type; the actual
bearing type can be seen from the presentation.
• The following two igures identify the ISO Dimension Series; the irst igure indicates the width or
Height series (dimensions B, T or H) and the second the Diameter Series (dimension D).
• The last two igures of the basic designation give the size code of the bearing; when multiplied by
5, the bore diameter in millimeters is obtained.
But there is no rule without some exceptions. The most important ones in the bearing designation
system are listed below.
1. In a few cases the igure for the bearing type and/or the irst igure of the Dimension Series,
identiication is omitted. These igures are given in brackets.
2. Bearing with bore diameters of 10, 12, 15, and 17 mm have the following size code identiications:
00 = 10mm
01 = 12mm
02 = 15mm
03 = 17mm
3. For some smaller bearings having bore diameter below 10mm, such as deep groove, self aligning
and angular contact ball bearings,. the bore diameter is also given in millimeters (uncoded) but is
not separated from the series designation by an oblique stroke.
4. Bore diameters that deviate from the standard bore diameter of a bearing have always been given
uncoded, in millimeters with up to three decimal places. This bore diameter identification is part
of the basic designation and is separated from the basic designation by an oblique stroke e.g.
6202/15.875 (d = 15,875mm = 5/8 in)
Series designations
The most common series designations are shown in diagram above the bearing sketches. The igures in
brackets are not included in the series designation.
Supplementary Designations:
Prefixes
Prefixes are used to identify components of a bearing and are usually then followed by the designation of
the complete bearing, or to avoid confusion with other bearing designations, for example they are used in
front of designations for taper roller bearings according to a system described in ANSI/ABMA standard 19 for
(predominantly) inch bearings.

1 > For normally to heavily loaded ball bearings ( P > 0,05 C), radial clearance greater than Normal is often needed when the shaft tolerances in the table above are used, Sometimes
the working conditions require tighter fits to prevent ball bearing inner rings from turning ( creeping) on the shaft. If proper clearance, mostly larger than Normal clearance is selected,
3 > For stainless steel bearings within the diameter range 17 to 30 mm , tolerance j5 applies.
4 > Bearings with radial internal clearance greater than Normal may be necessary
5 > Bearings with radial internal clearance greater than Normal are recommended for d ≤ 150 mm, For d > 150 mm bearings with radial internal clearance greater than Normal may be
necessary
6 > Bearings with radial internal clearance greater than Normal are recommended
7 > Bearings with radial internal clearance greater than Normal may be necessary. For cylindrical roller bearings radial internal clearance greater than Normal is recommended
> The tolerance in brackets apply to taper roller bearings. For lightly loaded taper roller bearings adjusted via the inner ring.
10 > Tolerance F6 can be protected for large bearings to provide easy displacement.

Self Aligning ball bearings
• These bearings are useful in application where small delection of shaft may our relative to housing.
• Self aligning ball bearing has lowest friction of all rolling bearing. So it allows running cooler even at
high speed.
• Can carry radial load, but not suitable for axial loads.
• Usable for low or medium speed application.
• Available with cylindrical bore or In certain size with tapered bore.
• Self aligning ball bearings with tapered bore are available with adapter sleeve.
• These bearings are provided with an annular groove and lubrication holes in outer and Inner ring.
• These type are recommended when the alignment of the shaft and housing is dificult. Since the
contact angle is small, the axial load capacity is low.
Misalignment
Self alignment ball bearing is designed in such a way that angular misalignment between inner and outer
ring can be accommodate without effecting on bearing performance.
Permissible Misalignment
This permissible misalignment of self-aligning ball bearing is approximately 0.07 to 0.12 radian (40o to
70o) under normal loads. However, depending on the surrounding structure, such an angle may not be
possible.

These bearings are made in cylindrical and taper bore. [K Bore] K Taper1:12 K30 = Taper 1:30 240XX and 241 XX Series
have a taper of 1:30, other series have a taper of 1:12
Sleeve : spherical roller bearings with tapered bore can be mounted on smooth or stepped shaft by using adapter sleeve &
withdrawal sleeve.
Misalignment
As these bearings are self aligning angular misalignment between inner and outer ring can be accommodate without any
effect on bearing performance. The permissible misalignment of spherical roller bearing varies depending on the size and
load but It Is Approximately 0.018 to 0.045 radian (1° to 2.5°) with normal load. The Limiting speed Is adjusted depending
on the bearing load Conditions. Also higher speeds are adjustable by making changes in the lubrication method. Cage
Design etc.
Series Available
Spherical Roller Bearings have two rows and roller with a common sphered raceway In the outer ring and two Inner ring
raceway inclined at an angle to the bearing axis. They are self aligning and consequently insensitive to misalignment of the
shaft with respect to housing and to shaft bonding.
These bearings are designed for high radical load, also accommodate high axial loads acting in both directions. An oil
groove and holes are provided in the outer ring to supply lubricant, to use bearings with oil grooves and holes, it is essen-
tial to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.
Another Feather in ZNL’s Research and Development Centers cap, by completely redesigning the Spherical Roller Bearings
with the help of advance computer aided design and unique methods of calculations. Tests are carried out on the ZNL test
rigs and in the field have confirmed the improved reliability and performance of the design.
ALL W33 Series bearings are manufactured with an oil groove and lubrication holes in the outer rings. Improved features
such as cage design, surface finish, stress distribution across the rollers and elimination of the rubbing surfaces lead to:
Doubling of expectancy and in some cases trebling for the same space envelope, due to the use of more reliable materials.
This allows smaller bearings to be used when machines are being redesigned. Doubling of static capacity allowing the
bearing to perform well In low speed applications under a very heavy load. Higher operating speeds that allow a wider
range of application. Better performance under shock loading and vibration is a valuable characteristic in difficult applica-
tions.

Cam Followers
ZNL Cam Followers are essential needle or cylindrical roller
bearings, which have a solid stud instead of the inner
ring. The stud is threaded so that the cam followers are
filled with grease and are ready to mount and ready to use
units.
MULTI -
ROW CYLINDRICAL ROLLER BEARINGS
Four – Row and Six – Row Cylindrical Roller Bearings are
used almost exclusively for the roll neck of rolling mill
stands, calendars and roller presses. They are of separable
design to considerably simplify bearing mounting, mainte-
nance and inspection.
ZNL four-row cylindrical roller bearings have a cylindrical
bore and some sizes are also available with a tapered bore
as sealed bearings, with a seal on one or both sides of the
bearing.

can accommodate axial, radial and moment loads acting
either singly or in combination and in any direction. They
are not mounted on a shaft or in house, the rings which
are simply bolted on the seating surface are available in
one of three executions:
• Without gears or
• With and internal gear or
• With an external gear.
