NSK

High seal peformance Ball bearing for Automotive Electric Motors
As a result of having repeated computer analysis and seal evaluation data, NSK developed the bearing with the high seal performance which prevented the invasion of the alien substance. This product enabled extension of life and the reliability improvement of ABS control system motors or the electric throttle control motors, and run control system motors of HEV and EV.
It is improvement more than ratio 10 times conventional by optimization of the length of the seal lip and a seal shape including the thickness and control the change of seal fitting change, and stabilizing seal lip anti-power and lip side pressure in seal characteristics of the bearing.
In addition, NSK control the rise of the bearing torque while increasing seal fitting to give seal performance and contribute to the consumption electricity reduction of the motor. Furthermore, this enables the minute control of the motor by suppressing the dispersion of the torque.
