Micro ball bearings are mechanical components that include outer rings, inner rings, balls, cages, shields and rings. The outer diameter of micro and small ball bearings is up to 60mm. Deep groove miniature ball bearings are single-row bearings and we offer a wide range of bearings. We have miniature bearings starting with a 1 mm internal diameter, which can be made of ceramic, chrome steel and stainless steel.
