Hybrid Ceramic Ball Bearing, 17x28x7mm, MR17287 RS, Silicon Nitride, Chrome Steel, Rubber Sealed

Experience superior performance with this MR17287 hybrid deep groove ball bearing, engineered for precision and durability. Featuring a 17mm inner diameter, 28mm outer diameter, and 7mm width, this bearing combines chrome steel rings with advanced black ceramic (silicon nitride) balls. The robust design includes a nylon cage and rubber seals on both sides for optimal protection. These bearings excel in demanding applications where traditional steel bearings may not perform as well, offering exceptional wear resistance and electrical insulation properties. Pre-lubricated with grease for smooth operation, these bearings are particularly well-suited for high-performance bicycle applications. The hybrid construction delivers a perfect balance of strength and reduced weight, making them an excellent choice for applications requiring precise, reliable rotation under varying conditions.
