Clamping elements are shaft-hub connections, which enable backlash-free and non-positive connection between cylindrical shafts and hub bores without keyway. There are selfcentering and non-self-centering clamping sets, which are used where key connections no longer meet requirements.
Benefits:
- Material saving due to smaller shaft and hub dimensions
- Simplified production processes
- Suitable for modern drive systems
- Simple assembly and disassembly with standard tools
- Ideal for drives with high alternating loads, like acceleration and braking
- Permanent non-destructive connections, i.e. no shearing off of keyways, dowel pins, bolts etc.
- Extremely suitable for high-speed drives
- Minimal sensitivity to dirt
- Multiple re-use
Please refer to the respective data sheet for more detailed properties of the individual clamping sets.
