Enduro Bearings Parts Enduro 6702 – 15 X 21 X 4

ABEC 3 radial bearing with 15 mm inner diameter, 21 mm outer diameter, 4 mm thickness and two-sided rubbing rubber sealing.

Enduro uses their ABC 3 bearing system with 10-grade chromium steel balls paired with a high carbon 52100 chromium alloy races. With high previous balls within 10/1.000.000 round, twice as round as the industry standard even at its premium.

The alloy races are made from a vacuum de-gassed process for the purest chromium alloy steel, hardened to R-62, extremely tough and very durable. 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.
