ENDURO BEARINGS B 539 llb max - abec 3 max (radial) - 3/4x1 3/16x1/4''

Enhance your mountain biking performance with the B 539 LLB MAX bearing, designed by Enduro Bearings to withstand the rigors of mountain bike pivots. This MAX-type, ABEC-3 radial bearing measures 3/4 x 1-3/16 x 1/4 inches and offers 35-40% higher load capacity than standard radial bearings, thanks to a specialized design featuring maximum balls inserted through custom ground race slots. The deep race grooves and increased ball count provide superior lateral support for twisting and multi-directional forces encountered in mountain biking. Constructed with 52100 high-carbon chromium alloy races and grade 10 balls with 90% fill, it is lubricated with Almagard high-pressure, waterproof grease. Commonly used as a direct replacement for Profile Racing Euro bottom brackets, this bearing is part of the Enduro line, available in various materials including high-carbon steel, 440C stainless steel, ceramic-hybrid, and XD-15 with ceramic or stainless steel balls. Features include deep groove races, dual-lip seals riding in micro-grooves, forming a labyrinth seal for optimal protection against dirt and water. Static load capacity is 850 lbf / 3.78 kN, with a weight of 14.6 grams.
