Description

Ceramic Lightning BK, yellow sealed bearings are specially designed for use with motorcycles, road/mountain bicycles and other demanding applications. The heavy duty rubber seal provides extra protection which makes the bearings maintenance free and lubed for the life of the bearing. These bearings have ceramic balls, with stainless steel races, C3 fit and polymite retainers. 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.
