Ceramic Lightning, shielded bearings are specially designed for relatively clean operating environments. These bearings have ceramic balls, with stainless steel races, retainers and shields. Ceramic hybrids are lighter, capable of achieving higher RPMÆs and sustaining higher operating temperatures than traditional bearings. Bearings that are packed in grease will require a short break in period to loosen up. Grease can be removed before shipping upon request. Grade 10 SI3N4 Ceramic Balls, ABEC #5, (.250x.625x.196)
