The Ringfeder RfN 7012 Locking Assembly is designed for applications in tight spaces, offering a compact form factor and tolerance compensation. It transmits high loads and torques, with multiple units capable of being arranged in series to add transmissible values. The assembly works without moving parts on the shaft and hub, ensuring it is free from wear and backlash, allowing for repeated clamping and release.
