Product detailed description
Bearing NU 4920 DKF
The NU 4920 DKF is a high-quality cylindrical roller bearing designed to provide excellent performance in a variety of industrial applications. Known for its durability and reliability, this bearing is engineered to handle heavy radial loads while ensuring smooth rotational movement.
This bearing features a double steel cage (DKF) which enhances the stability of the rollers, reduces friction, and improves the overall lifespan of the bearing. The NU design indicates that the bearing has two integral flanges on the outer ring and no flanges on the inner ring, allowing for axial displacement of the shaft relative to the housing in one direction. This makes it suitable for use in applications where thermal expansion or shaft misalignment occurs.
The NU 4920 DKF is widely used in machinery such as electric motors, gearboxes, conveyor systems, and heavy-duty industrial equipment. Its robust construction ensures reliable operation even under demanding conditions.
Key Features and Benefits
- High radial load capacity for heavy-duty applications
- Double steel cage (DKF) for improved roller guidance and reduced friction
- NU type design allows axial displacement, accommodating shaft expansion and misalignment
- Durable steel construction for extended service life
- Suitable for a broad range of industrial machinery
Investing in the NU 4920 DKF bearing means choosing a reliable component that enhances machine efficiency and minimizes downtime. Proper installation and maintenance will ensure optimal performance and longevity.
