Product detailed description
Bearing NU 322 ZKL: High-Performance Cylindrical Roller Bearing
The NU 322 ZKL is a premium cylindrical roller bearing designed to deliver exceptional durability and reliable performance in a wide range of industrial applications. Manufactured by ZKL, a trusted name in the bearing industry, this bearing model is engineered to handle heavy radial loads with precision and minimal friction.
This bearing is part of the NU series, characterized by its design that allows axial displacement of the shaft relative to the housing, which makes it ideal for applications where thermal expansion or shaft misalignment may occur. The “Z” in the designation indicates that the bearing is equipped with a single metal shield on one side, providing protection against dust and other contaminants while maintaining low friction.
Key Features and Benefits
- Robust Construction: The cylindrical roller design ensures high radial load capacity and long service life.
- Shielded Protection: The single metal shield (Z) helps prevent ingress of dirt and debris, enhancing bearing reliability.
- Axial Displacement Capability: The NU series design accommodates axial movement, reducing stress on bearing components.
- Precision Engineering: Manufactured to strict quality standards by ZKL, ensuring consistent performance and durability.
- Wide Application Range: Suitable for use in electric motors, gearboxes, pumps, and heavy machinery.
Technical Specifications
The NU 322 ZKL features a standard bearing size, with dimensions approximately as follows:
- Inner Diameter (d): 110 mm
- Outer Diameter (D): 170 mm
- Width (B): 28 mm
These dimensions comply with international bearing standards, ensuring compatibility with a variety of industrial equipment.
Applications
