Description

Ceramic Lightning BK, Ultra sealed bearings are specially designed for use with on road bikes but can be used in almost any application. The Ultra Seal is a non-contact, frictionless seal that is placed beneath a metal shields so they are still considered maintenance free and lubed for the life of the bearing. These bearings have ceramic balls, with stainless steel races and ploymite 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 usually be removed before shipping upon request.
