71801 LLB - ABEC-5 Angular-Contact Bearing (C3 Clearance) - 12mm x 21mm x 5mm

71801 LLB - ABEC-5 Angular-Contact Bearing (C3 clearance) - 12mm x 21mm x 5mm - Angular-Contact bearing generally used as a hub bearing for some quick-release hub designs, pedals, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use. This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, LLB seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements. When properly installed (black seal facing in) 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. The Enduro line of bearings are available in high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD15 with ceramic or stainless balls. Our bearings are always engineered with deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals
