Locking Assemblies RfN 7015.0
The Ringfeder RfN 7015.0 is designed for general engineering applications, offering reliable torque transmission and excellent centering performance in sizes from 100 mm to 800 mm.
In Vietnam & some Southeast Asian countries, Dai Hong Phat is an authorized distributor of Ringfeder Power Transmission.
Main characteristics of the Locking Assemblies RfN 7015.0
The RfN 7015.0 Locking Assembly is engineered for transmitting maximum torques and axial forces while maintaining high concentricity of the clamped parts and handling applications subjected to bending moments.
- High Peripheral Force Transmission: The long, flat cone design enables the RfN 7015.0 to transmit maximum torques and axial forces efficiently. During installation, the Locking Assembly, shaft, and hub stay in their relative positions, providing additional safety compared to three-part versions. Both the shaft and hub are solely compression-loaded.
- Combined Load Handling: Capable of transmitting bending moments and radial loads simultaneously. For assistance with combined loads, please contact our technical department.
- Exceptional Centering Ability: The RfN 7015.0 features a relatively wide design and a precentering web, ensuring excellent centering ability.
- Inner Diameter d: 100-800 mm
- Outer Diameter D: 145-910 mm
- Overall Length L: 77-227 mm
- Torque T: 14,244-2.5 Mio. Nm
