Product Overview: The NU 228 Cylindrical Roller Bearing
The NU 228 is a high-capacity single-row cylindrical roller bearing with dimensions of 140x250x42mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to handle substantial radial loads at high speeds. Its specific design, part of the NU 2200 Series, features two integral flanges on the outer ring and a flangeless inner ring. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications where thermal expansion or mounting inaccuracies occur.
Manufactured to exacting industry standards, the NU 228 offers exceptional reliability and a long service life in demanding industrial environments. The separable design, where the inner ring can be removed from the outer ring and roller assembly, simplifies both mounting and dismounting procedures, reducing downtime and maintenance complexity.
Key Features of the NU 228 Bearing
- High Radial Load Capacity: Line contact between rollers and raceways provides excellent support for heavy radial loads.
- Axial Displacement Accommodation: The flangeless inner ring allows for free axial movement, compensating for shaft expansion or misalignment.
- Separable Design: The inner and outer rings can be mounted independently, simplifying installation and inspection.
- High-Speed Capability: Engineered for low friction and optimal performance in high-rotational speed applications.
- Robust Cage Construction: Typically features a strong steel or brass cage for roller guidance, ensuring stability and durability.
- Precision Engineering: Manufactured with tight tolerances to ensure consistent performance and interchangeability.
Common Applications of NU 228 Bearings
- Industrial Gearboxes: Provides robust support for gears and shafts, handling the high radial forces common in gear systems.
- Electric Motors: Used as non-locating bearings on motor shafts to support loads while allowing for thermal expansion.
- Pumps and Compressors: Ensures reliable operation of rotating components under significant radial stress.
- Construction Machinery: Found in heavy equipment like excavators, cranes, and rollers where durability is critical.
- Rolling Mills: Withstands the extreme loads and high speeds characteristic of steel and metal processing.
- Vibrating Screens and Crushers: Ideal for machinery in mining and aggregate industries due to its high load capacity.
- Automotive and Railway Transmissions: Supports shafts and gears in heavy-duty vehicle powertrain systems.
