Features
Locking Devices provide a keyless, extreme high strength connection between components and round shafts. They feature a smooth, nonmarring bore which contracts securely onto a shaft while expanding the OD tightly into the I.D. of a hub. Fully adjustable, they are balanced to minimize vibration at high speeds,  and prevent backlash damage caused by heavy loads. 
1.Easy installed and removed: no heating,cooling or knocking while installation
2.Releasing and pushing  out screws without striking 
3.Random axial position and radial direction for installation 
4.Easy operation in narrow space 
5.Easy operation with giant machine parts 
6.Free from angular and axial backlash 
7.Overload protection in some occasions (prevent overload slipping) 
8.Key slot can be added to prevent overload slipping 
9.Shaft and hub can be designed smaller,lighter, cost and space saving 
10.Saving cost by reducing machining accuracy of shaft and hole
