Ball screws: with a capacity of 14,700 kg dynamic load
The ball screw is a mechanical system capable of converting rotary motion into linear and vice versa.
One of the best features of ball screws is the high performance obtained by rolling the ball between the spindle and the body of the nut. In these spindles, rolling friction occurs at the points where the balls touch the spindle and nut body. This is one of the best advantages offered by these spindles in comparison with other solutions alternatives such as ball screws, in which friction occurs across the surface of the thread of the ball screw with nut, being much higher friction.
Technical specifications: dynamic load rating 14,700 kg.
Static load rating 45,400 kg
