Enduro Max Sealed Cartridge Bearings with black oxide coated races are designed specifically for suspension pivots. Using a special design where the maximum number of balls are inserted into the bearing, they have more load capacity than standard radial bearings The race grooves are deeper on these bearings for more lateral support for the twisting and multiple forces associated with suspension pivots. LLU seals give maximum protection against the elements, while keeping the 90% fill of Almagard Extra High Pressure Grease inside.Black-Oxide/Magnetite coating provides an extra level of corrosion resistance and extended worry-free performanceItem SpecificationsBearing I.D.
