Bearing NU 4922 TNG DKF – High-Performance Cylindrical Roller Bearing
The NU 4922 TNG DKF is a premium cylindrical roller bearing designed for demanding industrial applications where durability, precision, and reliability are critical. Engineered to support heavy radial loads and high-speed operations, this bearing is an ideal choice for heavy machinery, electric motors, gearboxes, and other mechanical systems requiring robust load-bearing components.
This bearing features a NU-type design, characterized by two fixed ribs on the outer ring and no ribs on the inner ring, allowing axial displacement of the shaft relative to the housing in both directions. This design facilitates thermal expansion and misalignment without compromising performance.
Key Features of NU 4922 TNG DKF
- Type: Cylindrical roller bearing (NU design)
- Series: 49 series – suitable for large diameter shafts
- Sealing: DKF seals ensure effective protection against contaminants and retain lubricant for extended service life
- Material: High-quality bearing steel for excellent wear resistance and strength
- Precision: Manufactured to tight tolerances for smooth operation and minimal vibration
- Axial displacement: Supports axial movement, accommodating shaft expansion and misalignment
Applications of NU 4922 TNG DKF
This bearing is commonly used in:
- Heavy-duty electric motors and generators
- Industrial gearboxes and reducers
- Pumps and compressors operating under heavy radial loads
- Machine tool spindles and rotary tables
- Steel mills and mining equipment
The NU 4922 TNG DKF combines robust construction with advanced sealing technology, ensuring long service intervals and reduced maintenance costs. Its ability to handle substantial radial loads while allowing axial movement makes it indispensable in many industrial sectors.
