Product Overview: The NU 220 Cylindrical Roller Bearing
The NU 220 bearing is a robust and high-performance component within our extensive NU 200 Series and broader Cylindrical Roller Bearings collection. With precise dimensions of 100mm bore diameter, 180mm outer diameter, and 34mm thickness, this bearing is engineered to deliver exceptional performance in demanding industrial environments. Its defining characteristic is the absence of flanges on the inner ring, allowing the inner ring to be separated from the outer ring assembly. This separable design simplifies mounting and dismounting, particularly where components need to be installed independently.
As a key product among industrial bearings and mechanical parts, the NU 220 is specifically designed to accommodate heavy radial loads. The line contact between the rollers and raceways provides excellent rigidity and shock resistance, making it suitable for applications that experience high impact and vibration. Its high-speed capability further enhances its versatility across various machinery types. We supply NU 220 bearings manufactured to industry-standard specifications, ensuring reliability, longevity, and consistent performance for your critical operations.
