Product Overview: The NJ 309 Cylindrical Roller Bearing
The NJ 309 bearing is a high-performance component within our NJ 300 Series of Cylindrical Roller Bearings. This versatile bearing is engineered to provide exceptional performance in demanding industrial environments, particularly where high radial loads are present. With precise dimensions of 45mm bore diameter, 100mm outer diameter, and 25mm thickness, the NJ 309 is designed for robust applications requiring reliable rotational support.
As part of the NJ type, this cylindrical roller bearing features a separable outer ring with two integral flanges and an inner ring with one integral flange. This configuration allows the bearing to accommodate axial displacement in one direction, in addition to carrying substantial radial loads. Its design ensures excellent stiffness and precision, making it a critical component for various heavy-duty machinery. We supply top-quality industrial bearings, ensuring that our NJ 309 bearings meet stringent industry standards for durability and long-term operational efficiency.
Key Features of the NJ 309 Bearing
