1. Automobile bearings are used in following units of an automobile vehicle-
1.Wheel hub units-

2. Special bearings designed for engine water
pumps.
Excellent waterproof performance using
high-sealing seal. These bearings have life
three times longer than that of
conventional products.
A variety of sizes and types available.

3. Koyo clutch release bearings represent the
first truly clutch-compatible bearing with
its patented variable contact raceway
geometry.
This exclusive variable contact design
permits maximum speeds at maximum
loads, resists wear for longer life, and
minimizes noise and vibration.

6.  This bearing is used for High-Speed Railcars
(Wheel Bearings) in Axle Bearing Housing.
As rail speeds have increased in recent
years, manufacturers have begun using
7050, a high-strength aluminum alloy that is
forged at high temperature and pressure, for
railcar bearings (journal boxes). This reduces
their unsprung weight, gives cars greater
stability and reduces fuel consumption. This
is an important component supporting high-
speed vehicle travel.
 Specifiedlocation: Wheel journal box
 Advantage: Reduces wheel weight
 Production method: Stamp forging

7. Features-
1.Light weight,compact,energy saving.
2.High sealing performance by optimum lip design.
3.Low heat generation & Long service life by
highly self-lubricating self rubber materials.
4.High sealing performance & Long service
life by hydrodynamic ribs.

8. Sealed type four row
tapered roller
bearings for roll necks
Rolling equipment roll neck bearings having a sealed
construction.
Capable of improving the working environment and
reducing grease consumption.

9.  Bearing for cascade cold rolling machine.
 Outer rings are made of special bearing
material and heat treatment to achieve
surface hardness and impact
resistance, enabling them to bear loads from
contacting the middle rolls and have high
reliability.

10.  Slewing bearing is a large-scale integrated load
bearing, which can bear large axial load, radial load and
overturning moment.
Slewing ring bearings are generally of inner gear or outer
gear, mounting holes, lubrication holes (oil holes), and
seals, which can make the host be an compact
design, easy to guide and maintain.
Slewing bearings can be nongeared, internal gear and
external gear.
 The slewing bearing types are mainly as follows:
1. Four-point contact ball slewing bearings.
2. Double-row different diameter ball slewing bearings.
3. Crossed cylindrical roller slewing bearings.
4. cross-tapered roller slewing bearings.
5. Triple-row cylindrical roller slewing bearings.

11.  High-Precision bearings for machine tools-
High-Precision bearings used in machine tool
spindles, such as cylindrical roller bearings and
angular ball bearings.
 High ability bearings-
Series of ultraprecise angular ball bearings for machine
tool spindles.
Superior ultra high-speed performance. A variety of
types available that can meet all speed specification
needs.
 Support bearings for precision ball screws-
Support bearing unit combining a precision ball screw
support bearing (SAC) and precision machined housing.
Superior performance for assembing work.

12. 1.Environmentally friendly.
2.A variety of bearings for the main spindles, speed
accelerators, generators, etc. of windmill power
generators.

13. Basically in railway bearing is used for Rolling stock axle journals.
Bearing used to support rolling stock axle journals required to be
very strong & at the same time to be small because of limited
space.
1.Cylindrical Roller Bearings-
(Bore dia-85 to 133 mm)
Features-
Good high speed performance & can be maintained and
inspected easily because of their separable structure.
2.Sealed type Cylindrical Roller Bearing Units-
(Bore dia-95 to 120 mm)
Features-
Maintenance free: Pre lubricated with grease & provided with
oil seals.
It can be used with a simplified axle box or with an adapter
instead.
3.Tapered Roller Bearing Units-
(Bore dia- 101.6 to 177.787 mm)

14. Needle roller bearings are small in sectional
height,therefore useful in making machinery
smaller & lighter. This type of bearing is used in a
wide range of machinery such as automobiles,motor
cycles, electric machines,machine tools, aerospace
& office equipment.
Features-
Compact,highly rigid & superior in load carrying
performance.
Excellent for carrying oscillating loads, contains
many small diameter rollers.
Widely employed in stud & yoke type track rollers
used as guide rollers in linear motion units.
