Miniature precision hybrid ball bearings are one of our specialties. Ceramic hybrid ball bearings are made from 440C stainless steel rings with ceramic balls. One of the advantages of a hybrid design includes dissimilar materials, which prevents metal-to-metal welding. In the hybrid bearing, the 440C stainless steel rings and ceramic balls work in concert for smooth ball bearing operation. Another advantage of hybrid ball bearings is the lower weight of ceramic balls. This reduces ball bearing stress at the high rotational speeds that precision miniature and instrument ball bearings regularly experience.
