Bearing NU 4908 DKF: High-Quality Cylindrical Roller Bearing
The bearing NU 4908 DKF is a robust and reliable cylindrical roller bearing designed to handle heavy radial loads while providing smooth rotational performance. This bearing is widely used in various industrial applications, including electric motors, gearboxes, and heavy machinery, where durability and precision are essential.
Manufactured with high-grade materials and precise engineering, the NU 4908 DKF features a double flange design (indicated by the DKF suffix) that ensures optimal axial guidance and stability within the bearing assembly. Its design allows the inner ring to move axially relative to the outer ring, accommodating thermal expansion and shaft misalignment without compromising performance.
Key Features and Benefits
- Type: Cylindrical roller bearing, NU design
- Axial Guidance: Double flange on outer ring (DKF), for axial location of the bearing on one side
- Load Capacity: High radial load capacity suitable for heavy-duty applications
- Durability: Engineered for long service life under challenging operating conditions
- Versatility: Ideal for use in electric motors, pumps, compressors, and gearboxes
Technical Specifications
The NU 4908 DKF bearing conforms to international standards for cylindrical roller bearings, ensuring interchangeability and reliable performance. Dimensions for this bearing typically match the 4908 series standards, which include an inner diameter of 40 mm, an outer diameter of 68 mm, and a width of 24 mm, making it compatible with a wide range of industrial equipment.
Applications
This bearing is particularly suited for applications requiring high radial load capacity combined with the ability to accommodate axial displacement due to thermal expansion or shaft movement. Common uses include:
- Electric motors and generators
- Gearboxes and transmissions
- Pumps and compressors
- Heavy machinery and industrial equipment
Choosing the NU 4908 DKF ensures enhanced operational efficiency, reduced maintenance needs, and prolonged equipment lifespan. Its precision design and robust construction make it a trusted choice for engineers and maintenance professionals worldwide.
