Product Overview: The NJ 307 Cylindrical Roller Bearing
The NJ 307 bearing is a high-performance component from our comprehensive NJ Series of Cylindrical Roller Bearings, specifically part of the NJ 300 Series. Engineered for demanding industrial applications, this single-row cylindrical roller bearing features a bore diameter of 35 mm, an outer diameter of 80 mm, and a thickness of 21 mm. Its unique design includes a flanged outer ring and a removable inner ring, allowing for easy mounting and dismounting. This configuration makes the NJ 307 particularly suitable for applications where the inner ring needs to be separated from the outer ring and roller assembly.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our NJ 307 bearings meet stringent industry standards, offering exceptional reliability and extended service life. Cylindrical roller bearings like the NJ 307 are renowned for their high radial load carrying capacity and rigidity, making them indispensable in heavy-duty machinery. They are also well-suited for high-speed operations due to the line contact between the rollers and raceways, which minimizes friction and heat generation. Explore our full range of cylindrical roller bearings to find the perfect fit for your industrial needs.
