Enduro MRA 2437 LLB ABEC-5 ANGULAR (C3) BB BRNG 24 X 37 X 7MM

The Enduro MRA 2437 LLB ABEC-5 Angular Contact (C3) bottom bracket bearing, measuring 24x37x7mm, is engineered for durability and performance, particularly as a direct replacement for Shimano bottom brackets with a 24mm OD spindle. Featuring deep-groove races, Grade 10 balls, and dual-lip labyrinth (LLB) seals, it effectively withstands daily abuse and the elements, retaining its 90% fill of Mobilux NGLI 2 high-pressure waterproof synthetic grease. When correctly installed with the black seal facing inward, its angular contact design engages all balls, distributing force over a larger surface area to reduce friction, minimize wear, and significantly extend bearing life.
