Converting the rotary motion generated on the shaft to linear motion, screw shaft and nuts are auxiliary elements. Friction which constantly occurs during motion prepares an environment suitable for corrosion. There are balls housed in the gap between the nut and shaft. Screw shaft and nuts prevent corrosion caused by this motion. And the gear shafts provide easy motion in the ball housings having helical channels due to its sensitive screw structure. And when the friction is minimized, an efficient motion is obtained in mechanical sense.

Operating Principle of Screw Shaft and Nuts

Having high sensitivity, resistance and long lifetime, these shafts are used in the production machines dirty at low level. Supporting precise measurements of the machines, they are used in the equipment such as robots. It is important to protect it from dirt and various particles. In order to keep the operating surface free of dirt, rubber or leather bellows are used on the surface. Among the components, it is possible the biggest industrial part. As it is supportive and provides a clean operating environment, this component extends life of the bearings and, in turn, the machine.a
