Bearing NU 312 DKF – High-Quality Cylindrical Roller Bearing
The NU 312 DKF is a precision-engineered cylindrical roller bearing designed to handle heavy radial loads while providing reliable performance and durability. This bearing type is commonly used in various industrial applications, including electric motors, gearboxes, machine tools, and other heavy machinery requiring robust radial load capacity with minimal friction.
Featuring a double outer ring flange design (as indicated by the "DKF" suffix), this bearing ensures excellent guidance and axial location of the shaft without the need for additional components. The NU series bearings allow the inner ring to move freely in the axial direction relative to the outer ring, accommodating thermal expansion and shaft flexing effectively.
Key Features of NU 312 DKF
- Type: Cylindrical roller bearing with double outer ring flange
- Designed for heavy radial loads
- Allows axial displacement of the inner ring
- High load capacity with low friction coefficient
- Suitable for high-speed and high-temperature environments
- Durable steel construction for long service life
Dimensions and Specifications
The NU 312 DKF corresponds to the standard cylindrical roller bearing size 160 mm inner diameter, 260 mm outer diameter, and 50 mm width (160 x 260 x 50 mm). These dimensions conform to international bearing standards, making this bearing compatible with a wide range of industrial equipment.
Whether you are replacing worn-out bearings or designing new machinery, the NU 312 DKF provides reliable performance, ease of installation, and maintenance benefits. Its robust construction and design features make it an ideal choice for applications requiring high radial load capacity combined with some axial displacement capability.
Invest in the NU 312 DKF to ensure optimal machine performance, reduce downtime, and extend equipment lifespan with a trusted bearing solution.
