Screw jack, also known as helix transmission equipment, methodically change its rotation into linear motion--and vice versa . Some crew jacks serve for the weight lifting (such as press and lifting jack), some for the movement transmission(the shafts that connect platens). Some for the adjustment of relative location of parts.

 

  Screw jack lifting loadings in a single or multiple linkage way, which adjust its lifting or impelling height by a programmatically precise control or driven by motor or manually. With different structure and installation type, lifting height can be customized according to the actual requirements.

 

 

There are two kinds of structures of screw jack----trapezoidal sliding friction structure and ball rolling friction structure.

For trapezoidal screw jack, with the easy manufacturing, low cost and self-locking function, it has large a friction resistance torque and low transmission efficiency (30%~40%).

For ball screw jack, with its complication in structure and high cost, it cannot be self-locking, but the biggest advantage of that is the small friction resistance torque, the high transmission efficiency(92%~98%), its accuracy and stiffness. With the reversible motion, the long useful life makes it widely used in mechatronic systems. 

Screw lift , a basic lifting component, is widely used in all walks of life.

The stable structure of screw jack ensures a safer stability during use. The installation design is simpler and meets the different working conditions . Screw jack is widely used in industrial production, the processing cost is extremely low.The reduction of the production and processing costs will also increase the profitability.

 

Purchasing screw jacks in a professional and regular manufacturer, which not only ensures the fully utilization of functional advantages , but also achieves a longer useful life . Without worrying about costs wasting, the longer useful life achieves a higher comprehensive cost performance. Special maintenance is not neccesary, which guarantees good advantages than other products.
