Bearing Basics

ZXB Ball Bearing Construction

Ball bearings consist of rings with raceway (inner ring and outer ring), rolling elements and cage. The cage separates the rolling elements at regular intervals, holds them in place within the inner and outer raceways, and allows them to rotate freely.

ZXB ball bearings are classified according to their bearing ring configurations: deep groove type and angular contact type.

Deep groove ball bearings are widely used in a variety of fields, include shield bearings and sealed bearings with grease make them easier to use.

Angular contact ball bearings include single row and double row, open and shieled/sealed types. Single row angular contact ball bearings are self-retaining units with solid inner and outer rings and ball and case assemblies with polyamide, sheet metal , brass cage or phenolic resin,contact angle 15,25,30 &45 are available.

Double row angular contact ball bearings for which the inner and outer rings are combined as a single unit,the contact angle is 25.
