MSHKIN Locking Devices

MSHKIN Locking Devices are widely used for mechanical coupling under heavy loads. In the coupling of the gear and the shaft, it is a keyless coupling device that achieves load transfer by tightening the high-strength bolts to create the pressure and friction on the surface of the components. Under the action of the axial force, the inner casing of the locking device is inflated, so that the shaft and the hub are closely fitted, thereby generating sufficient friction to transmit torque and achieve the purpose of the mechanism.

Advantages of MSHKIN Locking Devices

  • 03 icon1

    Easy to Install

    Sufficient tolerances among the sleeves to make the entire installation and disassembly process easy and appropriate.

  • 03 icon2

    High Precision

    High precision ensures that MSHKIN locking devices are well balanced and suitable for high speed operation of the machines you make.

  • 03 icon4

    Lightweight

    The keyless coupling form enhances the torque transfer capability and makes the entire structure lighter by mechanical properties of the materials.

    Various Options

    MSHKIN offers a wide range of locking devices for most applications, as well as special non-standard products if you need.

MSHKIN Locking Devices Selection

Z11 Locking devices

Z11 type locking device assembly unit consists of four pieces with two inside double-cone rings through a set of tightening screws. It is recommended for medium torques. It can be easily assembled and disassembled.

Z7 keyless locking devices

Z7 Keyless locking device is a kind of the keyless coupling device between shaft and shaft sleeve. It can form mechanical compression between shaft and shaft sleeve by clamping shaft sleeve from outside. It does not transmit any torque and load.

Z3 Keyless Locking devices

Shaft Locking Devices connect hubs solidly to shafts, using a keyless mechanical interference fit, to transmit torque or to withstand axial thrust. This mechanical interference fit utilizes screw tension in the Shaft Locking Device, converted into radial pressure via an inclined plane. This pressure expands the Shaft Locking Device to eliminate the gap between the hub and the shaft. The Shaft Locking Device uses the friction bond between the Shaft Locking Device and the shaft/hub to create a zero backlash connection. This connection is easily releasable to remove the mechanical interference fit.
Easy assembly and disassembly
Both actions take place by locking and unlocking the clamping screws with common tools.
The use of a torque wrench is only necessary when a more precise torque is required.
Superior holding power
The action of the clamping cones creates shaft clamping torque superior to a normal keyed hub.
Overload protection

When the pre-set torque is exceeded locking device will slip, preventing the connected elements from being broken.
Note: Locking units are not friction couplings, so excessive slip will cause damage.
Easy adjustment
Combining the locking device design of smooth cone action with superior holding power, the hub can be clamped at any position along a shaft, eliminating the need for lock washers, spacers , stop rings, etc.

Z2 type locking device

Z2 type locking device assembly unit consists of four pieces with two inside double-cone rings through a set of tightening screws. It is recommended for medium torques. It can be easily assembled and disassembled.
