Product Overview: The NU 204 Cylindrical Roller Bearing
The NU 204 bearing is a high-performance component within our extensive NU 200 Series Cylindrical Roller Bearings. This particular bearing features a bore diameter of 20 mm, an outer diameter of 47 mm, and a thickness of 14 mm. It is specifically designed with no flanges on the outer ring, allowing for axial displacement of the shaft relative to the housing. This characteristic makes the NU 204 ideal for applications where thermal expansion or contraction might cause axial movement, preventing excessive axial stress on the bearing.
Our NU 204 bearings are engineered to handle high radial loads and operate at high speeds, making them a cornerstone for robust industrial machinery. As a trusted supplier of industrial bearings and mechanical parts, we ensure our cylindrical roller bearings meet stringent industry standards for reliability and durability. They are a critical choice for systems requiring precise guidance and the ability to accommodate axial movement, ensuring smooth and efficient operation across diverse industrial sectors.
