Z12B C45 Steel Shaft Locking Device for Printing Machine
Product Description
The shaft locking device is a new type of connection. It is a keyless coupling device that realizes load transmission by tightening high-strength bolts to generate positive pressure and the frictional force between the expansion sleeve and the shaft or between the containment surface of the sleeve. It has many unique advantages and characteristics compared with the traditional mechanical connection methods of non-bonded and keyed connections with general interference.

Advantages
1. The use of expansion sleeves makes the manufacture and installation of main machine parts simple.
2. Long service life.
3. The expansion sleeve will lose its coupling function when overloaded, which can protect the equipment from damage.
4. Can withstand a variety of loads.
5. Easy to disassemble.
