Bearing Enduro Bearings MR 18307 LLB ABEC 5 Ceramic Hybrid MR 18307 LLB ABEC 5 Ceramic Hybrid

CH MR 18307LB - ABEC-5, Ceramic-Hybrid, radial bearing (C3 clearance) - 18mm 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.

Radial bearing generally used as a hub bearing, as bottom bracket bearing for some older square taper BBs, 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 and feature dual-lip seals that ride in a micro-groove creating a full labyrinth to provide superior protection against the elements.
