Product Overview: The NU 304 Cylindrical Roller Bearing
The NU 304 bearing is a high-performance component from our extensive NU 300 Series within the larger family of Cylindrical Roller Bearings. This particular bearing, with its precise dimensions of 20mm bore diameter, 52mm outer diameter, and 15mm thickness, is engineered for demanding industrial applications requiring robust radial load capacity. Its 'NU' designation indicates that the outer ring has two integral ribs, while the inner ring is without ribs, allowing for axial displacement of the shaft relative to the housing. This design is crucial in applications where thermal expansion or contraction might occur, preventing unwanted axial loads on the bearing.
As a leading supplier of industrial bearings and mechanical parts, we ensure that our NU 304 bearings meet stringent industry standards, offering exceptional reliability and longevity. These bearings are indispensable in various machinery, providing stable and efficient rotational support under heavy radial loads. Explore our full range of cylindrical roller bearings to discover the optimal solution for your industrial needs.
