Product Overview: The NU 202 Cylindrical Roller Bearing
The NU 202 is a high-performance single-row cylindrical roller bearing, an essential component within our Cylindrical Roller Bearings collection. Part of the versatile NU 200 Series, this bearing is engineered with industry-standard dimensions of a 15mm bore diameter, 35mm outer diameter, and 11mm thickness. The NU design features two integral flanges on the inner ring and a flangeless outer ring. This configuration allows for easy mounting as the rings can be installed separately, and it expertly accommodates axial displacement of the shaft relative to the housing in both directions, making it ideal for non-locating bearing positions.
As a trusted supplier of industrial and mechanical parts, we ensure our NU 202 bearings provide exceptional radial load capacity and are suitable for high-speed applications. They are indispensable in machinery where thermal expansion and contraction of shafts occur, preventing stress and ensuring smooth, reliable operation.
Key Features of the NU 202 Bearing
- Separable Design: The inner and outer rings can be mounted independently, simplifying installation and maintenance procedures.
- High Radial Load Capacity: The line contact between rollers and raceways allows it to support heavy radial loads.
- Axial Displacement Accommodation: The NU design permits free axial movement between the shaft and housing, compensating for thermal expansion.
- High-Speed Performance: Engineered for low friction and minimal heat generation, making it suitable for high rotational speeds.
- Robust Construction: Manufactured from high-quality bearing steel for superior durability and an extended service life.
- Dimensional Stability: Precision-made to meet strict industry standards, ensuring reliable and consistent performance.
