Self-aligning ball bearings
Self-aligning ball bearings are double-row bearings with a spherical outer ring raceway. The
bearings therefore facilitate angle adjustment and are suitable for compensating for angular misalignment.
Self-aligning ball bearings are manufactured with cylindrical and tapered bores. The
bearings with tapered bore are predominantly fitted to shafts with adapter sleeves.
The cages of these bearings are normally made of glass-fibre reinforced Polyamide 66.
Bearings with these cages are marked with the designation "TNG". The cages of some of
the small bearings are made of Polyamide 66 without glass-fibre reinforcement. These are
marked with the designation "TN".
A very few bearings (Version J) are mass produced with cages made of pressed steel. The
bearings which are normally fitted with plastic cages are also available on request with
cages made of pressed steel "J".
Series 22.. and 23.. self-aligning bearings are also available sealed on both sides. These
bearings are marked with the designation "2RS".
The external dimensions of self-aligning ball bearings are laid down in ISO R15 or
Standards, dimensions
DIN 630.
The bearings are only manufactured to the standard tolerance P0.
Tolerances
Self-aligning bearings with cylindrical bores are normally manufactured with standard
Bearing clearance
radial clearance C0 and those with a tapered bore with radial clearance C3. Bearings
with other clearances are available on enquiry.
The clearances can be found in the table below.

Seals
NSK manufactures Series 22.. and 23.. self-aligning ball bearings, not only open version but also with seals on both sides of the bearing. These seals are made of nitrile
rubber and are reinforced with a steel disc embedded in the rubber. The seals are fixed
in the outer ring and seal against the inner ring with a friction sealing lip.
Sealed self-aligning ball bearings are filled with enough grease at the factory to last the
normal life span of the bearing. The bearings are therefore maintenance free. Note that
sealed self-aligning bearings have a lower load-carrying capacity than open bearings of
the same type. During installation, it is essential that they are not twisted, as otherwise
the seals may be forced out of position.
Angle adjustment facility
Self-aligning bearings facilitate angle adjustment. The permitted angle of tilt from the
central position for Series 12.. and 22.. open bearings is 2.5º and for Series 13.. and
23.. is 3º. With sealed bearings, the permitted angle of tilt is 1.5º.

DEEP-GROOVE BALL BEARINGS
Cages
Double-row, deep-groove ball bearings are normally manufactured with snap cages
made of glass-fibre reinforced Polyamide 66 and in a few cases, they are also provided
with solid brass cages.
M

Bearings with cages made of glass-fibre reinforced polyamide are suitable for operating temperatures up to +120ºC.
Weights
The weights shown in the dimension tables apply to the open version of the deepgroove ball bearings.
Angular adjustment facility
Because of their internal structure, double-row deep-groove ball bearings do not facilitate angular adjustment. When using these bearings, they must not be out of alignment.

ANGULAR-CONTACT BALL BEARINGS
Angular-contact ball bearings
Double-row
The structure and operation of double-row, angular-contact ball bearings correspond
to that of a pair of back-to-back mounted single-row angular-contact ball bearings. They
absorb radial and axial forces in both directions. The tilting moments can also be transferred. NSK supplies double-row angular-contact ball bearings with two different contact angles. The Series 32..J and 33..J bearings have a contact angle of 32º and are
fitted with a cage made of sheet steel. These bearings have filling slots on one side.
The bearings must therefore be installed so that most of the axial force is transferred
by the side without the slots.
The Series 32.. and 33.. bearings with the suffix "BTNG" have a contact angle of 25º
and are provided with a cage made of glass-fibre reinforced Polyamide 66. These
bearings do not have filling slots and can therefore transfer axial forces in both directions.
As well as the open version, NSK supplies double-row angular-contact ball bearings
with the suffix "BTNG" also with shield or seals on one or both sides of the bearing. All
Series 32..BTNG and 33..BTNG bearings are supplied with grease as standard. The version with the cage made of sheet-steel must be used for operating temperatures above
120ºC.
The external dimensions of double-row angular-contact ball bearings comply with
DIN 628.
Tolerances
Bearing clearance
The bearings are only manufactured to standard tolerance P0.
Double-row angular-contact ball bearings do not facilitate angular adjustment.
The axial clearance of double-row angular-contact ball bearings is specified. The
bearings are mass produced with axial clearance C0 "Normal". Other clearance groups
are available on enquiry. The axial clearances can be found in the table below.
The radial clearance of Version "BTNG" is approx. 45 % of its axial clearance.
The radial clearance of Version "J" is approx. 60 % of its axial clearance.

Double-row
Seals
As well as the open version, NSK manufactures double-row angular-contact ball
bearings with the suffix "BTNG" also with shield or seals on one or both sides of the
bearing.
Shields ZR
Shields ZR are sheet-steel discs which are fixed inside the bearing outer ring forming a
small gap for the bearing inner ring. The bearings are available with one shield on one
side of the bearing "ZR" or shields on both sides of the bearing "2ZR".
Seals RSR
Seals RSR consist of nitrile rubber and are reinforced with a steel disc embedded in the
rubber. The seals are fixed in the outer ring and seal against the inner ring with a friction
sealing lip. The bearings are available with one seal on one side of the bearing "RSR"
or seals on both sides of the bearing "2RSR".
Lubrication
With double-row angular-contact ball bearings, the gap between the cage and the rings
is relatively small. When lubricating with grease, it is therefore not easy for the user to
introduce the grease which is required for the initial lubrication. For this reason, NSK
also supplies non-sealed double-row angular-contact ball bearings pre-filled with grease
at the factory. The grease which is supplied is a high-quality lithium-based grease with
a temperature range of –30 ºC to +120 ºC. The grease used by NSK is compatible with
all other mineral-oil-based greases.
There is no problem using oil lubrication on bearings which have been lubricated with
grease by NSK, providing that the oil used is mineral-oil based. A special version of the
bearing is necessary for use with synthetic oils or greases. In these cases, please consult NSK.

Pulleys
Pulleys are developments of double-row angular-contact ball bearings with a reinforced
outer ring. The outer ring can be either of cylindrical or spherical design. The inner ring
of these bearings is provided with lubrication holes. The bearings have no filling slot and
absorb radial and axial forces in both directions. The contact angle of these bearings
is 25º. The bearing cage is made of glass-fibre reinforced Polyamide 66. Pulleys are
supplied with seals or shields on both sides. They are normally supplied filled with
grease at the factory. Special pulleys with galvanised bearing inner and outer rings are
also available on enquiry.
The bearings are only manufactured to the standard tolerance P0.
Tolerances
Double-row pulleys do not facilitate angular adjustment.
With double-row pulleys, the axial bearing clearance is specified. The bearings are nor-
Bearing clearance
mally supplied with axial clearance C0 "Normal". The axial clearances can be found in
the table below.
The radial clearances are approx. 45 % of the axial clearances.

Double-row pulleys are fitted with cages made of glass-fibre reinforced Polyamide 66.
NSK manufactures pulleys with seals and shields on both sides of the bearing.
Shields are sheet-steel discs which are fixed inside the bearing outer ring forming a
small gap for the bearing inner ring. The bearings are available with shields on both
sides "2ZR".
Seals RSR
Seals RSR consist of nitrile rubber and are reinforced with a steel disc embedded in the
rubber. The seals are fixed in the outer ring and seal against the inner ring with a friction
sealing lip. The bearings are available with seals on both sides of the bearing "2RSR".

PULLEYS
Lubrication
NSK supplies pulleys filled with grease at the factory. This is a high-quality lithiumbased
grease with an admissible temperature range of –30 ºC to +110 ºC. The grease used
by NSK is compatible with all other mineral-oil-based greases. The inner rings of the
pulleys are provided with a lubrication hole so that bearings can be re-lubricated. With
Version 2RSR, the grease must be pressed in slowly to avoid damaging the seals.
Bearing load capacity
If the pulley is supported by a flat contact surface, only a small surface area of the outer
ring of the pulleys comes into contact with the rolling plane. The elastic deformation of
the outer ring reduces the load-bearing capacity of the pulley. In this case, the values
specified in the "Pulley load ratings" table must be used in the calculation.
On the other hand, when installing the pulley in a housing bore, the "Bearing load
ratings" apply which are also listed.
