Bearing Enduro Bearings CO 6902 VV Enduro Zero Black-Oxide Ceramic Hybrid

CO 6902 VV Enduro Zero, Black-Oxide, ceramic-hybrid radial bearing, ABEC-5, with C3 clearance – 15mm x 28mm x 7mm.

The Enduro Zero ceramic-hybrid ABEC-5 radial bearing features black-oxide-treated 52100 high-carbon chromium alloy races and Grade 5 silicon-nitride ceramic balls. It uses high-pressure, waterproof grease with a 90% fill. Si3N4 ceramic balls reduce bearing wear and extend bearing life by eliminating steel-on-steel contact inside the bearing. The black-oxide (magnetite) treatment provides the races with additional corrosion resistance. VV seals are our lightest-contact design, allowing this bearing to spin faster than any other bearing we make, though they offer less protection from the elements than LLB or LLU type seals.

Radial bearings are generally used as hub bearings and can also be used as pivot bearings, although the MAX-type version of this bearing is better suited for suspension use.

The Enduro line of bearings 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 race grooves to accommodate the largest balls. Dual-lip seals sit in a micro-groove, creating a labyrinth for protection against the elements.
