Product Overview: The NU 213 Cylindrical Roller Bearing
The NU 213 Cylindrical Roller Bearing is a high-performance component engineered to manage substantial radial loads at high speeds. With principal dimensions of 65mm bore diameter, 120mm outer diameter, and 23mm thickness, this bearing is a key part of our Cylindrical Roller Bearings collection. Its specific design, part of the NU 200 Series, features two flanges on the inner ring and a flangeless outer ring. This configuration allows the bearing to act as a free-end bearing, expertly accommodating axial displacement of the shaft relative to the housing in both directions, which is crucial for applications with thermal expansion.
As a leading supplier, we provide NU 213 bearings that are precision-manufactured to meet stringent industry standards. The separable design simplifies both mounting and dismounting procedures, making it a practical choice for maintenance-intensive machinery. Its line contact geometry between the rollers and raceways minimizes friction, ensuring efficient and cool operation even under heavy loads.
Key Features of the NU 213 Bearing
- High Radial Load Capacity: Designed with cylindrical rollers that provide a large contact area to support heavy radial forces.
- Axial Displacement Accommodation: The NU design allows the shaft to move axially in either direction relative to the housing, preventing stress from thermal expansion.
- Separable Design: The inner ring, with its roller and cage assembly, can be mounted separately from the outer ring, simplifying installation and inspection.
- Low Friction Operation: The line contact between rollers and raceways is optimized to reduce friction and minimize heat generation.
- High-Speed Capability: Precision engineering and robust cage design make it suitable for applications requiring high rotational speeds.
- Durable Construction: Manufactured from high-purity, hardened bearing steel for exceptional durability and a long service life.
Common Applications of NU 213 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as the non-locating bearing to support the motor shaft and compensate for thermal growth.
- Pumps and Compressors: Ensures reliable rotation of shafts in demanding fluid and gas handling equipment.
