Product Overview: The NU 238 Cylindrical Roller Bearing
The NU 238 is a high-capacity single-row cylindrical roller bearing with dimensions of 190x340x55mm. As a key component in our Cylindrical Roller Bearings collection, this bearing is engineered to withstand heavy radial loads and operate effectively at high speeds. A defining feature of the NU Series is its design where the inner ring has two integral flanges and the outer ring is flangeless. This configuration allows the bearing to accommodate axial displacement of the shaft relative to the housing in both directions, making it ideal for applications with thermal expansion or potential mounting inaccuracies.
Manufactured to exacting industry standards, the NU 238 offers exceptional reliability and a long service life in demanding industrial environments. Its separable design simplifies the mounting and dismounting process, as the inner ring can be fitted independently of the outer ring and roller assembly. This feature is particularly advantageous for maintenance and installation in large machinery.
Key Features of the NU 238 Bearing
- High Radial Load Capacity: The line contact between the rollers and raceways provides excellent support for heavy radial forces.
- Axial Displacement Accommodation: The NU design allows for free axial movement, preventing stress caused by shaft expansion or contraction.
- Separable Design: The inner ring can be removed, which simplifies installation, inspection, and maintenance procedures.
- High-Speed Capability: Engineered for low friction and minimal heat generation, making it suitable for high-speed rotational applications.
- Robust Construction: Made from premium-grade bearing steel for superior durability, wear resistance, and operational longevity.
- Dimensional Stability: Precision-engineered to ensure consistent performance and interchangeability.
Common Applications
