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.
