Locking assemblies

Meeting individual customer requirements - and keeping everything securely clamped in place

Locking assemblies are used for force-fit (friction-fit) and backlash-free transmission of torque and axial forces between shafts and hubs or machine components.

The advantages of friction-fit torque transmission over keyway connections are as follows:

  • Permanent and non-destructive connection
  • Fast and clean installation and disassembly
  • Ability to perform positioning in the axial direction on the shaft
  • Torque transmission with simultaneous acceptance of axial forces
  • Depending on the model, can be re-used multiple times
  • Absolutely backlash-free - ideally suited for use with servo technology and for reversing duties
  • Partial overload protection for machine parts through slippage
  • Better fatigue factors
  • Material savings for shaft-hub dimensions
  • No special surface finish required
  • Larger tolerance field in the shaft-hub diameter range
  • No fretting corrosion

We offer solutions with mechanical locking assemblies and also with hydraulic and hydromechanical locking bushes.
