BB MRA 2437 LLB-bag | 24 x 37 x 7mm Bearing

MRA 2437 LLB - ABEC-5 Angular-Contact Bearing (C3 Clearance) - 24mm x 37mm x 7mm This Angular-Contact ABEC-5 bearing features deep-groove design races, with Grade 10 balls, dual-lip labyrinth (LLB) seals to withstand daily abuse of use and the elements, and to contain the 90% fill Mobilux NGLI 2 high pressure water proof synthetic grease. When properly installed (black seal facing in) and adjusted, Enduro Angular Contact (A/C) bearings engage all of the bearing's balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. The most common use for this bearing is as a direct replacement bearing for Shimano bottom brackets with a 24mm OD spindle. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
