Product Overview: The NJ 2214 Cylindrical Roller Bearing
The NJ 2214 bearing is a high-performance single-row Cylindrical Roller Bearing, part of our robust NJ 2200 Series. With principal dimensions of a 70mm bore diameter, 125mm outer diameter, and 31mm thickness, this bearing is designed for applications demanding high radial load capacity and rigidity. Its unique design features a separable inner ring with two flanges and an outer ring without flanges, allowing for axial displacement in one direction. This makes the NJ 2214 bearing particularly suitable for applications where thermal expansion or contraction of the shaft must be accommodated.
As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NJ 2214 bearings are manufactured to rigorous industry standards, providing exceptional durability and reliable performance in demanding industrial environments. These bearings are critical components in various machinery, offering smooth, low-friction operation even under heavy operational conditions.
