Product detailed description
The NU 222 C3 STEYR is a single-row cylindrical roller bearing engineered for high radial load capacity and high-speed applications. Its design includes two integral flanges on the outer ring and no flanges on the inner ring, enabling axial displacement in both directions. The separable design simplifies mounting and allows for component interchangeability.
Technical Specifications:
- Bore Diameter (d): 110 mm
- Outside Diameter (D): 200 mm
- Width (B): 38 mm
- Dynamic Load Rating (C): 335 kN
- Static Load Rating (C₀): 365 kN
- Reference Speed: 3,600 rpm
- Limiting Speed: 4,000 rpm
- Radial Internal Clearance: C3
- Cage Type: Non-metallic
- Number of Flanges on Outer Ring: 2
- Number of Flanges on Inner Ring: 0
- Lubrication: None (requires external lubrication)
- Sealing: Open (no seals)
- Material: Bearing steel
- Weight: Approximately 4.8 kg
This bearing is suitable for applications requiring high radial load capacity and high-speed operation, such as electric motors, gearboxes, and pumps. The C3 radial internal clearance ensures sufficient space for thermal expansion during operation. The non-metallic cage reduces friction and wear, contributing to a longer service life.
