Locking devices and clamping units

Safe connection between shafts and hubs

Keyless shaft-hub connections

What are locking devices for shaft & hub?

Shaft locking assemblies or shaft locking systems are keyless shaft-hub connections for shaft drives. They ensure a friction-locked connection between shaft and hub. Miki Pulley has developed and continuously improved a locking assembly design and manufacturing method to deliver a superior locking device at a favorable cost.

Where are locking assemblies used?

Our ranges are ideal for positioning and locking shaft components in a system and eliminate the need for keyways, tapers and threaded holes that can weaken shaft couplings or cause excessive wear.

What distinguishes the locking assemblies from Miki Pulley?

Using Miki Pulley locking assemblies instead of a keyway has many advantages, including: less time required, easy assembly and disassembly, uniform radial surface pressure and higher torque value.

Our locking elements can save valuable time and resources in many production processes. The locking assemblies offer high torque transmission (Nm) and an improved design characterized by excellent axial and radial concentricity. We also offer a wide range of adaptable shaft diameters.

How are locking devices for shaft & hub assembled and maintained?

Our locking assemblies are maintenance-free. For installation, the locking assembly is simply slid over the shaft and the sprocket or pulley is pushed onto the locking assembly body.
