Bearing Enduro Bearings MR 20307 LLB ABEC 3

MR 20307 LLB – ABEC-5 radial bearing (C3 clearance), measuring 20mm x 30mm x 9mm.

This ABEC-3 bearing has deep-groove races, Grade 10 balls, light-contact dual-lip labyrinth LLB seals, and a 90% fill of high-pressure, waterproof grease to withstand daily use and exposure to the elements.

Bearings of this size are generally used in front hubs, particularly those from Mavic and Profile Racing. Trek also uses them as suspension pivot bearings, although the MAX version is better suited to suspension applications.

The Enduro bearing line includes high-carbon chromium steel, 440C stainless steel, ceramic-hybrid and XD-15 bearings with ceramic or stainless steel balls. The bearings are engineered with the deepest possible groove races to accommodate the largest possible balls. Their dual-lip seals ride in a micro-groove, creating a labyrinth seal for long service life and protection against the elements.
