S71806 LLB 30x42x7 Bearing

Angular-Contact, ABEC-5, Bottom Bracket Bearing featuring 440C stainless steel alloy races and balls with 90% fill, high-pressure, water-proof grease for maximum corrosion resistance. When properly installed (black seal in for BBs) 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. 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.
