Front bearing In general, bearings are used on the front and rear sides of the alternator (one bearing for each side ) in order to support the rotor. Ball bearings are used, except in some types of alternators. High-performance bearings are required to satisfy the high temperature and speed requirements as well as to resist water, vibration, etc. JTEKT has developed high-performance bearings for alternator based on the results of many years of research and offers an outstanding lineup.

(1) Bearing specifications support high temperatures and speeds as well as providing white structure flaking resistance A new grease has been adopted to ensure high-temperature/speed performance and anti-white structure flaking properties required for alternator bearings. Example of high-temperature/speed performance test (dm*n*: 7.3 x 105, 170°C) (2) Supporting use in harsh external environments The adoption of the RM seal, featuring advanced water resistance, enables problem-free use of alternators in harsh external environments (water, dust, etc.) Amount of water (g) Example of water...
