Seiko develops low torque thrust needle roller bearings for automotive air conditioning compressors

Seiko has developed a thrust needle bearing (Thrust Needle Bearing) that can reduce the torque during rotation for a vehicle air conditioner compressor. Compared with the original, the torque during rotation is reduced by about 40%, which is expected to improve the efficiency of the compressor.
In combination with the shape of the bearing roller, the shape of the retainer pocket is changed, and the torque at the time of rotation is reduced by adopting a configuration in which the roller end face is in contact with the outer diameter flange of the retainer. The fuel efficiency of the car when using the air conditioner can be increased by about 1%.
