Miniature Ball Bearings
Miniature ball bearings are small metal ball bearings that are less than 1 inch in diameter. These small-profile mini ball bearings provide precise rotational performance and offer light-load capacities. USARollerChain ball bearings are of high quality and tested for proper performance. These tiny ball bearings are shielded or sealed and are offered with or without a flange. The shielded and sealed bearings can be pre-lubricated to ensure smooth rotation, and the shielding and sealing may help provide protection from particles and dirt inadvertently becoming ingrained in the bearing cage, which would reduce performance. Flanged outer rings help mount the bearings. Applications include the medical industry and industrial hand-pieces, flow meters, fuel controls, motors, cryogenic coolers, servos, gyros, and imaging equipment. As with a typical ball bearing, these smaller ball bearings can be purchased with components made out of stainless steel, a corrosion-resistant material for harsher environments.
