Product Description


To adapt the development trend of automotive accessory with dedicated, customized and unitized, we combined characteristics of automotive products, focus on research and development of Automotive Bearings and related parts, hub bearings, tension bearings, clutch release bearings, Steering Bearings, water Pump Bearings (WB sereis, WR series), Vane Pump retaining ring, spherical roller, cam blocks, and other Auto Parts.

Dedicated designed for automotive alternator, using a light seal structure of two-point contact clearance type, and with special grease which is good quality , high efficient, long life, and low noise. These all ensure bearings meet requirements of automotive generator, which are high-rotation speed and high reliability.


1. High-speed running of bearing inner ring;

2. Temperature of operating environment above 120 ℃;

3. Surrounding of bearings with water vapor, dust;

4. Contact with mud sometimes;

5. Soak in water in special time;

6. Use in high-temperature and alpine region;

7. High requirement of limiting speed;

8. Operate inside a magnetic field, prone to have white flaking;

9. Can withstand operating conditions both of rapid acceleration and rapid deceleration.


1. The sealing performance requirements:do not allow water, vapor or dust leak into bearing;

2. Bearing requirements of high performance high speed;

3. High and low working temperature from -40℃ ~ 180℃;

4. Low starting torque:the light contact seal;

5. The use of long life:in accordance with the requirements of automotive; bearings, life test requirements of more than 1000h.

Alternator /Generator Bearings


The Material Selection of Bearing Components:

1. Rings adopted by high-purity specialty quality bearing steel;

2. Steel balls are from famous brand manufacturers, that effectively guarantee materials and processing accuracy;

3. Using glass fiber reinforced nylon cages;

4. Sealed with high quality acrylic rubber;

5. Using synthetic oil (base oil) + Polyurea (thickening agent) Grease.

Alternator /Generator Bearings


1. Sealed with tri-lips light contact structure-- having supper sealing performance, and suitable for high-speed operation;

2. Using engineering plastic cages with oil reservoir structured-- effectively increase the lubrication capability of bearings;

3. Optimize the groove curvature of outer ring and the raceway of inner ring-- suitable for high-speed and reduce axial movement;

4. Some bearing's OD with nylon expansion ring or "O" type ring-- prevent creeping.
