Miniature Ball Bearings 68 Series are non-separable and require little attention or maintenance in service, capable of operating at high speeds and are widely used radial bearings. Miniature & Instrument Ball Bearings 68 Series can carry much heavy axial loads after the increase of radial clearance, thus, it can take the place of high speed Angular Contact Ball Bearings.
