Product Summary:
Locking assemblies are used in mechanical engineering to create a frictional shaft-hub connection. The Locking assemblies connects the hub of a gear, for example, to a shaft by means of a frictional connection. This backlash-free connection between shaft and hub allows reliable transmission of torques as well as axial forces. Depending on the design of the clamping set, high bending moments can also be transmitted with this type of connection.
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

Quality control:
1) ISO 9001, every product must be tested.
2) Quality guarantee: one year after receiving.
Jiuwei had entered the machinery field since 2006, and established factory to produce high-quality worm shaft and gears in 2007 with only 12 sets machines.
With the rapid development of the industry, our performance has steadily improved. During several years, we had more than 30 sets CNC machines in our workshop to produce high-quality worm gear, worm shaft, screw, housing and all parts. We had became a very provassfional and technical expert, and made deep friendship with many clients and manufacturers in transmission field.
To provide better service for our global clients, our trading service department was independent and Jiuwei company was established.
And now we have all kinds of machines and testing equipments, covering lathes, drilling machines, hobbing machines, CMM etc. We can produce more than 250,000pcs reducers per year with stable and reliable quality, which have service in steel industries, food machinery, packaging machinery, textile machinery, woodworking machinery, chemical machinery and lifting equipment etc. Our products have been exported to Europe, Southeast Asia, the Middle East, South America and Africa markets.
We continue to believe that our products, services and the value they add to our customers' businesses remain the fundamental elements of our continued success.
