ENDURO BEARINGS Co mr 2437 vv - zero ceramic (radial) - 24x37x7

Experience superior durability with the CO MR 2437 VV enduro-grade, ceramic-hybrid radial bearing. Measuring 24mm x 37mm x 7mm, this high-performance bearing features Black-Oxide treated 52100 high-carbon chromium alloy races paired with Grade 5 Silicon-Nitride ceramic balls filled to 90%. Equipped with high-pressure, waterproof grease, it reduces wear and extends bearing life by eliminating steel-on-steel contact. The Black Oxide/magnetite treatment enhances corrosion resistance for worry-free performance. VV seals offer minimal contact for faster spinning, ideal for high-speed applications, though less protective than LLB or LLU seals. Perfect as a direct replacement for Shimano-style external cup bottom brackets and cranksets with 24mm spindles. Available in various materials including high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. Designed with deep groove races and dual-lip labyrinth seals for optimal protection against elements. Static load: 773 lbf / 3.44 kN | Weight: 18.86 g
