What are BallScrews?
| Linear Ballscrews |
|
Ballscrews are, so to speak, screws equipped with a number of ball bearings and internal ball recirculation between screw and nut. The profile of the screw track has been rounded to provide for better adaptation to the recirculating balls. The main advantage of ballscrews is their higher degree of efficiency, that means, the ratio between utilisable energy and applied one. Other advantages of ballscrews are long life and low wear. As ballscrews have no self-locking capability brakes have to be attached where necessary to prevent returning. In practically every application the ballscrew contributes its important part to the comprehensive performance and determines, to very large extent, the price of the final product as such ballscrew belongs generally to the most expensive purchased parts. Highly sophisticated production engineering includes a standard range of miniature ballscrews in the diameter bandwidth from 3 mm to 16 mm as well as various standardised screw designs of nominal diameter from 16 to 100 mm. Due to the outstanding and innovative nut technology such as internal ball recirculation and patented pre-loading system, manufacturing nuts of minimum outer diameter for special applications is possible. This is particularly true for those users whose drive assemblies have already been dimensioned. |
