A wide variety of bearing types and design variations are available to meet the requirements of virtually all precision instrument applications. Bearing types include radial retainer, pivot, thrust, high speed radial, angular contact and full ball complement. Many selections also are available in both inch and metric dimensions.Miniature ball bearings can be open or shielded, which helps prevent dirt from entering and lubricant from leaking out, and unflanged or flanged for easier plate mounting. Some miniature ball bearing options feature extended inner rings to help fit certain locking devices when a press fit is not possible.

Miniature Precision Ball Bearings for Specialized Industries. Miniature Precision Bearings are identified by having an internal diameter of less than 3/8 inches (9.5 mm) while still containing the same components used in standard radial ball bearings.
