Product Overview: The NJ 2308 Cylindrical Roller Bearing
The NJ 2308 bearing is a high-performance single-row Cylindrical Roller Bearing, designed for applications requiring high radial load capacity and moderate axial load in one direction. As a core component within our NJ 2300 Series, this bearing features two integral flanges on the outer ring and a single integral flange on the inner ring, allowing it to accommodate axial displacement in one direction only. With its precise dimensions of 40mm bore diameter, 90mm outer diameter, and 33mm thickness, the NJ 2308 is engineered for robust and reliable operation in demanding industrial environments.
Known for their high stiffness and low friction, NJ 2308 bearings are ideal for machinery where precision, durability, and efficiency are paramount. The separable components (inner ring, outer ring, and roller-cage assembly) simplify mounting and dismounting procedures, making them a preferred choice for various industrial setups. Our commitment to supplying high-quality industrial bearings ensures that the NJ 2308 meets stringent industry standards, offering extended service life and reduced maintenance requirements for your critical operations.
