MR 21531 LLB – ABEC-3, Radial Bearing (C3 Clearance) – 21.5mm x 31mm x 7mm
This ABEC-3 bearing features deep-groove design races, with Grade 10 balls, light-contact, dual-lip, labyrinth (LLB) seals and 90% fill with high pressure water proof grease to withstand daily abuse of use and the elements.
A bit of an oddball size, this bearing generally used as a front hub bearing, specifically for older WTB 20mm hubs. It has also been used for Isis bottom brackets.
The Enduro line of bearings are available in High-Carbon Chromium Steel, 440C Stainless Steel, Ceramic-Hybrid and XD-15 with Ceramic or Stainless Balls. Our bearings are always engineered with deep groove races to accommodate the largest balls possible. All of our standard bearings feature dual-lip seals that ride in a micro groove creating a full labyrinth to provide ultimate protection against the elements.
