The NSK four-point contact ball bearings have been designed to meet oil-free screw compressor manufacturers' demanding requirements. The bearing consists of an outer-ring guided brass cage that has strength of a higher order and balls that make angular contacts of 35 degrees at four points.

The angular contact of the balls produces a low amount of friction, low noise, low downtime and increased limiting speed, which leads to enhanced and increased service life. The bearing delivers an efficient performance and reliability resulting in increased productivity. Due to the contact angle, it features a high axial load capacity and also offers a narrow axle clearance range.
