ENDURO BEARINGS 71806 llb a5 - abec 5 (angular contact) - 30x42x7

71806 LLB - ABEC-5 Angular-Contact Bottom Bracket Bearing Upgrade your cycling performance with the 71806 LLB bottom bracket bearing, featuring ABEC-5 angular-contact design for optimal load distribution and durability. Crafted with high-quality 52100 high-carbon chromium alloy races and Grade 5 balls with 90% fill, this bearing is packed with high-pressure, waterproof grease for reliable performance. When properly installed (using the black seal for bottom brackets) and correctly adjusted, the angular contact design ensures all balls engage simultaneously, spreading forces over a larger surface to minimize wear and extend bearing life. Ideal for applications like BB30, PF30, BB386, and other 30mm spindle bottom brackets, this bearing offers a robust solution for demanding cycling conditions. Available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls, our bearings feature deep groove races to accommodate larger balls and dual-lip seals with micro-grooves for superior element protection.
