ABEC3 6903 Wheel Bearing

Enduro ABEC3 6903 Wheel Bearing 17x30x7 (Single)

Enduro ABEC3 6903 Wheel Bearing 17x30x7 (Single) features the bearing specialists high precision, Grade 10 chromium steel balls that are within 10/1,000,000″ round, twice as round as the industry standard.

These precision balls ride in a 52100 high carbon chromium alloy race, hardened to R-62 to make them extremely tough and durable. Mirror finish polishing of the races creates ABEC-3 precision and noiseless movement.

The bearing is labyrinth sealed with two NBR 70 full-contact, medium-high friction seals, which ride in a groove machined into the bearing. Combined with marine grease, this seal creates an almost impenetrable barrier to contamination.
