ENDURO 71806 BOTTOM BRACKET CARTRIDGE BEARING

Introducing the 71806 LLB - ABEC-5 Angular-Contact Bottom Bracket Bearing, measuring 30mm x 12mm x 7mm.

This Angular-Contact, ABEC-5-rated bottom bracket bearing is designed with 52100 High-Carbon Chromium alloy races, coupled with grade 5 balls featuring a 90% fill. Infused with high-pressure, water-proof grease, this bearing, when correctly installed (with the black seal inside for BBs) and adjusted, engages all of the bearing's balls through Enduro Angular Contact (A/C) technology. This strategic design spreads force over a larger surface area, minimizing wear and enhancing bearing life. This is particularly critical in bottom brackets (BBs) where varying lateral loads constantly impact the bearings, often leading to premature failure.

Primarily utilized as a direct replacement for BB30, PF30, BB386, and most other bottom brackets with a 30mm OD spindle, this Enduro bearing is engineered for durability and optimal performance.

Enduro offers bearings in various materials, including high-carbon chromium steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless balls. Regardless of the material, these bearings feature deep groove races to accommodate large balls and incorporate dual-lip seals riding in a micro-groove, forming a full labyrinth for superior protection against the elements.

Technical Specifications:

• Static Load: 854lbf / 3.80kN
• Weight: 22.4g

Choose the Enduro 71806 LLB for a reliable, high-performance bottom bracket bearing that stands up to the demands of dynamic cycling conditions.
