NTN Wheel Bearing 6904-2RS / 6904LLU/5K — easily replace the worn bearing in your hub with this radial bearing designed for motorcycle applications. Designed for wheel/swingarm assemblies, it features an inner diameter of 20 mm, outer diameter of 37 mm, and a width of 9 mm, a standard size for many two- and four-wheeled applications.
The double sealing (2RS / LLU) limits the entry of water and dust, which reduces maintenance and protects internal lubrication. Compact and robust, this bearing is intended for urban, quad, motocross, and roadster use, where reliability and mounting neutrality are required. It easily installs in the hub to restore precise rolling and freedom of rotation of the rolling assembly.
This component is aimed at motorcyclists and mechanics who seek a safe replacement part that meets industrial standards. Check the dimensions 20x37x9 and the manufacturer reference before ordering to ensure compatibility with your model.
