ABOUT
Kogel Hybrid bearings use premium grade Silicon Nitride (Si3n4) Bearings and premium hardened steel bearing races which are mirror polished to perfection. The result? A long lasting, smooth bearing which provides less resistance and is less prone to failures. These bearings are rated to the Grade 3 / ABEC 5 level - built to spin with minimal friction.

All Kogel bearings come with a "1 + 1" Warranty.
Year 1 - we employ the "very few questions asked" method...
Year 2 - we ask that a full service be undertaken to ensure contamination is not the cause of issue prior to processing a warranty claim.  We recommend following the Kogel bearings service manual, ref to resources tab.

Services are undertaken at a low cost and is something we recommend yearly anyway - a great way to keep your bearings happy and healthy.
