1. Sintered Oil Impregnated Bearing
Oil is impregnated into the pores between alloy material structure provides self-lubricating function. Achieve lower friction coefficient under low-speed / high-specific pressure conditions and are suitable for the following applications:
* Transportation Machines; * Industrial Machinery; * Office Machines;
* Electric Motors; * Home Appliances; * Audio Equipment

2. Ceramic Ball Bearings
The ceramic ball bearing is mainly made of ZrO2, SiC, Si3N4 or Alumina, or Carbon, among which is of excellent performance and has become the preferred material for ceramic ball bearing.
For the low density and high hardness, self lubricating without oil, preventing surface damage and various features, the ceramic ball bearings are going to be the best choice for high-speed rotation application, such as high-speed wheel head bearing, machine spindle bearing, instrument bearing high-speed motor spindle bearing.

3. Deep Groove Ball Bearings
These bearings are mainly used to support radial load and certain amount of axial load. If enlarged the radial internal clearance of these bearings. The bearings have the futures of the angular contact ball bearings and can support heavier axial load. They have a less frictional resistance and a high limiting speed, so can operate satisfactorily under high-speed condition. Operating temperature is from -30℃ to +120℃.
Bore diameter is from 10mm to 70 mm.
Typical applications: automobiles, motorcycles, electric motors, home appliances, industrial equipment.
6000 , 6200 , 6300 , 6400 , R , RLS , RMS , 1600 series, etc.

4. Thrust Ball Bearings
They are suitable for the accommodation of axial load in one direction and can locate a shaft in one direction. They can not be subjected to any radial loads.
Main items including 51100, 51101, 51200, 51201 and etc.

5. Tapered Roller Bearing
These bearings have tapered inner and outer raceways between which tapered rollers are arranged. If extended, the tapered surfaces converge toward a single point on the bearing axis. They are particularly suited for combined loads (radial and axial).
Metric series and Inch series.
