Factory Links OEM Series® Rear Wheel Bearing Kit for Yamaha YZ and WR – OEM-Spec Bearings & Seals | RWK-Y-146

Factory Links OEM Series Rear Wheel Bearing Kits are engineered to withstand the higher torque loads, sustained radial stress, and heat exposure experienced at the rear hub of off-road, enduro, dual-sport, and motocross motorcycles. Designed to meet or exceed OEM specifications, each kit includes premium deep groove ball bearings and Nitrile Butadiene Rubber (NBR) double-lip oil seals—manufactured to strict dimensional tolerances for proper axle alignment, drivetrain stability, and smooth rear wheel rotation under power. Unlike generic aftermarket replacements, Factory Links rear wheel bearings are pre-packed with a heavy-duty marine-grade grease and specialized thickener blend designed to resist breakdown under high load, chain tension, and elevated operating temperatures. Rear wheel bearings operate under continuous drivetrain load from the chain and sprocket assembly—placing greater demand on load capacity, internal clearance, and sealing performance. Factory Links bearings are engineered specifically for these conditions, delivering long service life in demanding environments. Each kit includes all required components for a complete rear wheel hub rebuild—including bearings, oil seals, and model-specific spacers (where applicable)—helping eliminate wheel play, restore drivetrain precision, and maintain reliable performance in mud, water, sand, and extreme off-road conditions. This kit fits the following Yamaha motorcycles:Rear WheelYamahaWR 250 F (2001-2003)WR 400 F (1999-2000)WR 426 F (2001-2002)WR 450 F (2003-2003)YZ 125 (1999-2020)YZ 250 (1999-2020)YZ 250 F (2001-2008)YZ 400 F (1999-1999)YZ 426 F (2000-2002)YZ 450 F (2003-2008)
