In order to face the exhaust the throttle control car motor and ExhaustGasRe-circulationSystem EGR (the motor problems, Japanese seiko NSK import bearing developed low torque grease of seal bearing.
Usually, in order to reduce torque,DU bushing are in the motor assembly as director of the rotation, to reduce the initial resistance, grease, the viscosity of the ingredients reduce oil. But, this kind of practice Mould guide plate is the key problem of not only break-in rotation is time-consuming, and reduce the oil viscosity, under high temperature when using can shorten life. Therefore, the Japanese seiko corporation through addition of grease in nanoscale particles to reduce resistance grease. That way, compared with the original,plasic bushing not only can more quickly, and even if bearing stable torque in high temperature can keep a long life.
