Product Overview: The NJ 308 Cylindrical Roller Bearing
The NJ 308 bearing is a high-performance component from our comprehensive NJ Series of Cylindrical Roller Bearings. Designed with a bore diameter of 40 mm, an outer diameter of 90 mm, and a thickness of 23 mm, this single-row cylindrical roller bearing features a flanged inner ring and a flanged outer ring, but with one of the outer ring flanges being detachable. This configuration allows the bearing to accommodate axial displacement in one direction, while still providing robust support for high radial loads. Its separable design facilitates easier mounting and dismounting.
As a trusted provider of industrial bearings and mechanical parts, we ensure that our NJ 308 bearings are manufactured to the highest industry standards. These bearings are indispensable in applications requiring exceptional rigidity, minimal friction, and reliable operation under heavy radial stress. They are particularly well-suited for machinery where precise positioning and smooth rotational movement are critical, even in demanding industrial environments.
