Fig. 1.1 Nomenclature for Bearing Parts. 1.TYPES AND FEATURES OF ROLLING BEARINGS The NSK bearing unit is a combination of a radial ball bearing, seal, and a housing of high-grade cast iron or pressed steel, which comes in various shapes. The outer surface of the bearing and the internal surface of the housing are spherical, so that the unit is self-aligning. The inside construction of the ball bearing for the Screw compressors are used in environments where they are exposed to such chemicals as compressor oil, refrigerants, and ammonia gas. Consequently, bearings for screw compressors must be highly resistant to oil and heat. NSK bearings for screw compressors feature polyphenylene sulphide (L-PPS) plastic cages
