Bearings has a huge selection of Miniature Bearings and Instrument Series Ball Bearings with over 500 types available. Precision tolerances from ABEC-1 through ABEC-9 are generally available for most miniature products. Typical bore sizes of miniature ball bearings start at 3 mm with an outside diameter a mere 10 mm. Custom-made miniature bearings can have bore sizes as small as 1 mm!

Miniature bearings from Grainger can offer precise rotational performance for applications with light-load capacities. 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. Shop Grainger to help find miniature bearings to fit your application.
