ABEC 3 radial bearing has a 12.7 mm (1/2") inner diameter, 28 mm outer diameter, 8 mm thickness, and two-sided rubber sealing.

A radial bearing is generally used as a hub bearing for some quick-release hub designs but is more often used in wheelchairs. This ABEC-3 bearing features deep-groove design races, with grade 10 balls, LLB seals, and 90% fill with high-pressure waterproof grease to withstand the daily abuse of use and the elements.

The Enduro line of bearings is 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 the deepest groove races possible to accommodate the largest balls and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.

Features

• ABEC 3 bearings use grade 10 Chromium Steel Balls and 52100 High Carbon Chromium Alloy Races.
• The high precision balls are within 10/1.000.000 round, twice as round as the industry standard, at its highest level.
• The alloy races are made from a vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough, durable, and polished to a mirror finish for ABEC-3 precision and noiseless movement. The riveted Steel Retainer stands for toughness, ABEC-3 tolerances, and noise tested.
