Electric Accessory and Engine Bearings
Overview
Vehicles include a vast array of electrical accessories such as engine starters, air-conditioning systems for a comfortable riding environment, windshield wipers for safety, and oil-pressurized motors to assist power steering. These days, we cannot even imagine a vehicle on the road without these components. Unlike household appliances, these parts are exposed to extreme temperatures and vibrations. Therefore, they are equipped with far more durable and reliable bearings. NSK's advanced bearing technology has revitalized the automobile industry with such items as a clutch pulley unit for alternators, which is an automotive power source.

Electrification Products
Extends the operating life of anti-lock braking systems (ABS) by preventing oil from entering the motor and enabling operation at higher pressures. This technology can be applied in all types of oil pumps, including motors for brake system control systems.
By optimizing the composition of grease components, we improved ball bearing wear resistance in high-vibration environments.
Bearings for Alternator
The pulley unit with a one-way clutch decreases belt noise and extends belt life by absorbing the speed fluctuation transmitted through the crank pulley.
Highly reliable alternator bearings that offer high performance under high-temperatures conditions, high speed, with sealing features. Includes creep prevention function between the bearing and housing.
Bearings for Compressor
Magnetic clutch bearings with high sealing performance, high moment rigidity, and long life.
High durability under the alternative coolant (non-Freon type) and high rotating speed.
High durability under the alternative coolant (non-Freon type) and high rotating speed.
Bearings for Motors
Reduced weight and costs have been achieved with pressed outer ring.
Long life for high temperature and brush wear particle conditions have been achieved with special grease.
EPS motor bearing for low torque, low vibration, and high reliability.
Low torque for low temperatures and long life under high temperatures has been achieved with newly developed exclusive grease.
