CH 71903 LLB - Ceramic-Hybrid, ABEC-5, Angular-Contact Bearing (C3 clearance) - 17mm x 30mm x 7mm -
This ABEC-5, Ceramic-hybrid bearing features deep-groove design 52100 High-Carbon Chromium alloy races, with grade 5 Silicon-Nitride Ceramic balls, dual-lip labyrinth (LLB) seals to withstand the outside elements, and to contain the 90% fill Mobilux NGLI 2 high pressure water proof synthetic grease. Si3N4 Ceramic balls reduce bearing wear and increase bearing life by eliminating steel on steel contact within the bearing. When properly installed (black seal facing in) and adjusted, Enduro Angular Contact (A/C) bearings engage all of the bearing's balls to spread the force over a larger surface area, decreasing friction, minimizing wear and increasing bearing life.
Angular-Contact bearing generally used as a front hub bearing, and can be used as a pivot bearing, though the MAX-type version of this bearing is better suited for suspension use.
The Enduro line of bearings are 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 deepest groove races possible to accommodate the largest balls possible and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
