Features
- Versatile, Self Retaining bearings
with solid outer rings, inner rings and ball and cage
assemblies
- Available in Single and Double
Row designs and in open and sealed variants
- Robust in operation and easy to
maintain
- Low frictional torque, therefore
suitable for high speeds
Radial and Axial Load Capacity
- Use of raceway geometry supports
axial loads in both directions as well as radial loads
Compensation of Angular Misalignments
- The angular adjustment facility
of single row deep groove ball bearings is limited,
so the bearing positions must be well aligned.
- Misalignments can lead to unfavorable
ball running and induce additional loads in the bearing
that shorten the operating life.
ANGULAR
CONTACT BALL BEARINGS
Single
Row Angular Contact Ball Bearings
|
In single row angular ball
bearings, the raceways are arranged such that
the forces are transmitted at a particular contact
angle-oblique to the radial plane-from one raceway
to the other.
The axial load carrying capacity
increases with the contact angle. Due to the large
contact angle, single row angular contact bearings
are more suitable than deep groove ball bearings
for supporting large axial forces acting in one
direction.
Features
- Bearings with self-retaining
units with solid inner and outer rings and ball
and cage assemblies with polyamide, sheet metal
or brass cages.
- Available in open and sealed
designs
.
- Raceways of inner and outer
rings are offset from each other along the bearing
axis.
X-Life
A significant feature that is
exclusive these FAG bearings. Bearings with X-Life
have improved rceway geometry and optimized surfaces.
This gives a significant increase in the fatigue
limit load of the bearings. When calculating the
expanded adjusted rating life, values up to 50%
higher can be achieved.
Radial and Axial Load Capacity
- Can support axial forces
in one direction and high radial forces.
- The Axial load carryine capacity
is dependent on the contact angle, i.e. the
larger the angle, the higher the load the bearing
can be subjected
.
- The 40 degree contact angle
supports high axial loads.
Universal Design
- Single row angular contact
ball bearings of universal design have the suffix
UA,UL or UO and are intended for fitting in
pairs in an X, O or tandem arrangement or fitting
in groups. These bearings can be fitted in any
arrangement required
.
- The suffix UA indicates small
axial internal clearance, suffix UL indicates
slight preload and suffix UO indicates freedom
from clearance in an X or O arrangement
.
- When ordering bearings, the
total quantity of bearings must be stated, not
the number of bearing pairs or bearing groups.
ANGULAR
CONTACT BALL BEARINGS
Double
Row Angular Contact Ball Bearing
|
| Double Row Angular Contact
ball bearing are similar in design to a pair
of single row angular contact ball bearings
in an O arrangement. In this case, the apexes
of the cones formed by the ball pressure lines
point outwards.
Double row bearings can support high radial
forces as well as axial forces in both directions
and are particularly suitable for rigid
axial guidance arrangements.
Features
- Units with solid inner and outer rings
and ball and cage assemblies with polyamide,
sheet metal or brass cages
.
- Construction to single angular contact
ball bearing in an O arrangement but narrower
to an extent
.
- Available in sealed and open designs
.
- Sealed bearings are maintenance free
and allow for economical bearing arrangements.
Radial and Axial Load
Capacity
- Double Row angular contact bearings
can support axial forces in both directions
and high radial forces
.
- Particularly suitable for arrangements
when rigid axial guidance is required
- Axial load capacity is dependent on
contact angle, higher the angle higher
the load that the bearing can be subjected.
Without Filling Slot
- Bearings of series 38.B,30..B and 33..B
are self retaining and do not have filling
slots in the end faces of the bearing
rings.
- Their axial load carrying capacity is
the same in both directions.
BALL
BEARINGS
Four Point Contact Bearings |
Features
- These bearings
are single row angular contact ball
bearings and therefore require significantly
less space in an axial direction
than double row designs.
- Bearings comprise
solid outer rings, split inner rings
and ball and cage assemblies with
brass and polyamide cages.
- Two-piece inner
rings allow a large complement of
balls to be accommodated.
- Inner rings halves
are matched to the particular bearing
and must not be interchanged with
those of other bearings.
- Outer rings with
the ball and cage assembly can be
mounted separately from the two
inner rings halves.
Axial Load Capacity
in both directions
- The design of
the rolling element raceways with
their high raceway shoulders, the
contact angle of 35 degree and the
large number of rolling elements,
four point contact bearings have
a high load carrying capacity.
With or without
retaining slots in the outer ring
- Single row four
point contact bearings capable of
supporting axial loads in both directions
are often combined with a radial
bearing and used as an axial bearing
with radial clearance in housing.
- For quick and
secure location, larger four point
contact bearings therefore have
two retaining slots in the outer
ring offset by 180 degrees. These
bearings have the suffix N2.
BALL
BEARINGS
Self- Aligning Ball Bearings |
Features
- Bearings
with double-row, self-retaining
units comprising outer rings
with a concave raceway, inner
rings with a cylindrical or
tapered bore and ball and
cage assemblies. Available
in open and sealed designs.
Radial
and Axial Load Capacity
- Self-aligning
ball bearings can support
axial forces in both directions
as well as radial forces.
With cylindrical/tapered bore
- Bearings
of series 12,13, 22 and 23
are available with a cylindrical
or tapered bore.
With adapter
sleeve
- Self-aligning
ball bearings with a tapered
bore are also available with
an adapter sleeve, locknut
and tab washer.
With extended inner ring
- Bearings
of series 112 have an extended
inner ring, a location slot
on one side of the inner ring
and are located by means of
dowel pins.
BALL
BEARINGS
Spindle Bearings |
| Features
- Spindle
Bearings are single row angular
contact ball bearings with
solid inner and outer rings
and ball and cage assemblies
with solid window cages
- Cannot
be dismantled
- Open and
sealed designs
- Have restricted
tolerances
- Particularly
suitable for bearing arrangements
with very high requirements
for guidance accuracy and
suitability for high speeds
Radial and Axial Load Capacity
- Bearings
can support axial forces in
one direction as well as radial
forces. Spindle bearings used
in an O or X arrangement can
support axial forces in both
directions and moments.
X-Life
- Most spindle
bearings are X-Life ultra
bearings. These bearings have
bearing rings made from a
corrosion-resistant steel
that contains nitrogen and
has a particularly fine structure
(prefix X) and ceramic balls
- They fulfill
very high requirements for
speed and load carrying capacity
- These bearings
have longer life compared
to conventional bearings
Types
- These bearings
are available in two types,
i.e. standard spindle bearings
and high speed spindle bearings
- Standard
spindle bearings have steel
balls and the high speed ones
have ceramic balls
