ENDURO BEARINGS Co mr 9227 vv - zero ceramic (radial) - 9x22x7

Upgrade your cycling performance with the CO MR 9227V Enduro Zero radial bearing, designed for high durability and precision. Featuring black-oxide treated 52100 high-carbon chromium alloy races paired with Grade 5 Silicon-Nitride ceramic balls filled to 90%, this ceramic hybrid bearing offers exceptional wear resistance and extended lifespan by eliminating steel-on-steel contact. The ABEC-5 accuracy ensures smooth rotation, while the waterproof, high-pressure grease guarantees reliable operation in tough conditions. The VV seals provide minimal contact for maximum spin speed, ideal for high-performance cycling applications. Slightly larger than a standard 608 bearing with a 9mm inner diameter, it is perfect for Mavic freehub bodies. Available in various materials including high-carbon chromium steel, 440C stainless steel, and ceramic-hybrid, all engineered with deep groove races and dual-lip labyrinth seals for superior protection against the elements. Static load capacity: 295 lbf / 1.31 kN. Weight: 10g.
