Enduro SMRA 2437 LLB Angular Contact Bearing - ABEC-5, 440C Stainless Steel races and Balls, 24mm x 37mm x 7mm

Enduro Angular Contact bearings engage all of the bearing's balls to spread the force over a larger surface area, minimizing wear and increasing bearing life. This is particularly important in applications like BBs, where there are constantly changing lateral loads on the bearings, which is typically the primary cause for premature bottom bracket bearing failure.
