Product Overview: The NJ 215 Cylindrical Roller Bearing
The NJ 215 bearing is a robust and high-performance component within our extensive NJ Series of Cylindrical Roller Bearings. Featuring a bore diameter of 75 mm, an outer diameter of 130 mm, and a thickness of 25 mm, this bearing is engineered for applications demanding high radial load capacity and moderate axial load in one direction. The 'NJ' designation signifies that the outer ring has two integral flanges, while the inner ring has a single integral flange. This configuration allows for axial displacement of the shaft relative to the housing in one direction, making it suitable for applications where axial movement needs to be accommodated while maintaining precise radial guidance.
As a leading provider of industrial bearings and mechanical parts, we ensure that our NJ 215 bearings are manufactured to rigorous industry standards. These bearings are indispensable in various heavy-duty machinery, offering exceptional reliability, smooth operation, and extended service life even under challenging conditions. Explore our full range of cylindrical roller bearings to find the optimal solution for your industrial requirements, ensuring enhanced machine performance and reduced downtime.
