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

? 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
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.
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.
? 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.
? 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.
? 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.
1.Environmentally friendly.

2.A variety of bearings for the main spindles, speed
  accelerators, generators, etc. of windmill power
  generators.
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)
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.
