Product Overview: The NJ 203 Cylindrical Roller Bearing
The NJ 203 bearing is a high-performance, single-row Cylindrical Roller Bearing specifically designed for applications requiring robust radial load capacity and axial displacement accommodation in one direction. Part of our comprehensive NJ 200 Series, this bearing features a flanged inner ring on one side and a flangeless outer ring. This configuration allows for excellent guidance of the shaft in one axial direction while permitting relative axial movement between the shaft and housing in the opposite direction. With precise dimensions of 17mm bore, 40mm outer diameter, and 12mm thickness, the NJ 203 is engineered for durability and reliability in demanding industrial environments.
As a trusted supplier of industrial NJ Series bearings and mechanical components, we ensure that our NJ 203 bearings meet stringent industry standards. Their design makes them particularly suitable for applications where thermal expansion or contraction of the shaft is expected, providing stable and efficient operation.
