Precision Ball Screws for Maximum Performance
Precision ball screws require the perfect interplay between nuts, balls and ball screw shaft. The individual parts ground in very tight tolerances are brought to the highest level of precision through the manual assembly by highly skilled specialists.
Only the highest quality materials are used to produce the components. The wear-resistant, long-term nitrided surfaces of all the ball screws as well as the through-hardened nuts and balls, optimal ball recirculation systems and effective wipers guarantee the high load capacity and precision over a very long useful life.
The high geometrical accuracies and the preload of the double nuts in 2-point contact during assembly are the basis for the high nut rigidity with simultaneously very low inner friction. This is also reflected in the very high system efficiency and in the low idling and breakaway torques.
The even torque curve, the high level of smooth running and the lowest possible vibration tendency over the entire thread length minimize the power loss and therefore also the heat development, regardless of whether the ball screw is lubricated with oil or with grease.
The installation and load direction of precision ball screws is generally arbitrary and does not affect its functionality.
The designs and the connection dimensions of the precision ball screws conform with DIN ISO 3408 or DIN 69051 or correspond to individual customer requirements as special designs.
