Ceramitech Bearings: Our Si3n4 hybrid ceramic bearings feature ultra-spherical silicon nitride balls matched to SAE 52100 chrome steel bearing races that have been processed with additional heat treatment and polishing steps. The result is a hybrid-ceramic bearing that lasts longer than any steel bearing with spin performance no steel bearing can rival. We’re so confident in the durability of our Ceramitech bearings that we back them with a Lifetime Bearing Exchange warranty. These bearings feature mid-contact seals for extreme performance and endurance. Each bearing comes lubricated with Kluber Isoflex Topas NB52. Lifetime Warranty.
