Product Overview: The NU 2219 Cylindrical Roller Bearing
The NU 2219 is a high-capacity single-row cylindrical roller bearing with dimensions of 95x170x43mm. As part of our extensive Cylindrical Roller Bearings collection, this component is engineered to handle heavy radial loads at high speeds. The 'NU' designation signifies that it features two integral flanges on the outer ring and a flangeless inner ring. This specific design allows for axial displacement of the shaft relative to the housing in both directions, making it ideal for use as a non-locating bearing.
Manufactured to precise industry standards, the NU 2219 from our NU 2200 Series offers exceptional reliability and a long service life. Its separable design, where the inner ring can be mounted independently from the outer ring and roller assembly, greatly simplifies installation, inspection, and maintenance procedures. This bearing is a critical component in various demanding industrial applications where robust performance and accommodation for shaft expansion are required.
Key Features of the NU 2219 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent capacity for heavy radial loads.
- Axial Displacement Capability: The NU design allows the shaft to move freely in both axial directions relative to the housing, accommodating thermal expansion.
- Separable Design: The inner ring is separable from the outer ring and cage assembly, simplifying mounting and dismounting.
- High-Speed Performance: Engineered with precision cages to operate effectively at high rotational speeds with low friction.
- Robust Construction: Manufactured from premium-grade bearing steel for superior durability and resistance to wear and fatigue.
- Low Friction Operation: Optimized internal geometry minimizes friction and heat generation, enhancing operational efficiency.
