Product Overview: The NU 220 Cylindrical Roller Bearing
The NU 220 is a high-capacity single-row cylindrical roller bearing designed to handle heavy radial loads and high-speed applications. With precise dimensions of 100mm Bore Diameter, 180mm Outer Diameter, and 34mm Thickness, this bearing is a crucial component in demanding industrial machinery. As part of our NU 200 Series, the NU 220 features a separable design where the inner ring can be removed. This characteristic not only simplifies mounting and dismounting procedures but also allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for accommodating thermal expansion. Explore our comprehensive range of Cylindrical Roller Bearings to find the perfect solution for your equipment.
Features of the NU 220 Bearing
- High Radial Load Capacity: Engineered with line contact between rollers and raceways to support substantial radial forces.
- Separable Inner Ring: The NU design allows the inner ring to be separated, facilitating easy installation and maintenance.
- Axial Displacement: Accommodates thermal expansion of the shaft by allowing the inner ring to move axially in either direction relative to the outer ring.
- High-Speed Performance: Optimized internal geometry and cage design reduce friction and heat, enabling operation at high rotational speeds.
- Robust Construction: Manufactured from premium-grade bearing steel for superior durability, wear resistance, and extended service life.
- Interference Fit: The separable design permits an interference fit for both the inner and outer rings, ensuring a secure mounting.
