Automobile Alternator Bearings B8-23D-2RS, Ecb8-23D-2RS

Product Description

The bearings of automobile alternator are exposed to harsh environments such as electric brush wear, dust, and external dust, mud, and water. The bearings must have good sealing performance and be able to withstand high loads by driving the alternator rotor through V-shaped ribbed pulleys; With the continuous improvement of automobile performance, higher requirements have been put forward for the performance of automobile engines and alternator. The maximum speed of the motor has exceeded 20000rpm, and the bearings must have ultra-high speed performance; Automobile alternator require low friction torque, and the bearings of automobile alternator must meet low starting and rotating torque requirements; Long lifespan, high reliability, and other requirements.
The bearings of automobile alternator have the following characteristics:
1. The inner and outer rings, as well as steel balls, require materials with high purity and special treatment to obtain excellent organization; And high-precision positional tolerances, excellent working surface morphology;
2. The retaining frame material has sufficient strength to maintain high-speed and high-temperature characteristics;
3. The sealing structure and sealing components have high-performance sealing, heat and wear resistance, as well as good oil and grease inertness and stability;
4. Lubricating grease has excellent resistance to bearing fatigue peeling, high and low temperature stability, and leakage resistance. Recommended technical requirements:
Lubrication: Japanese Kyodo yushi Multemp ET-K, German Klueber Or Customer specified grease
