Product Overview: The NU 218 Cylindrical Roller Bearing
The NU 218 bearing is a high-performance component within our extensive NU Series Cylindrical Roller Bearings. With precise dimensions of a 90 mm bore, 165 mm outer diameter, and 39 mm thickness, this bearing is engineered to deliver exceptional reliability and efficiency in demanding industrial applications. Its defining characteristic is the absence of flanges on the inner ring, which allows for axial displacement of the shaft relative to the housing. This design makes the NU 218 ideal for applications where thermal expansion or contraction might occur, or where axial movement needs to be accommodated without generating undue stress on the bearing or other machine components.
As a trusted supplier of industrial bearings and mechanical parts, we ensure that our NU 218 bearings are manufactured to rigorous industry standards. These bearings excel under heavy radial loads and are suitable for high-speed operation, making them a crucial choice for various types of rotating machinery. Explore our full range of cylindrical roller bearings to discover robust solutions for your specific industrial requirements.
