Ball Screw Drives

General

Ball screw drives made by isel are precise and abrasion-resistant drives with a good value for the money.
Here rotary motions are effectively and almost frictionless converted into linear movements with a repitition accuracy of less than 0.01 mm (related to a length of 300 mm).

The ball screw drives consist of hardened and ground ball screws Ø 16 mm and Ø 25 mm with pitches of 2.5/5/10 and 20 mm as well as hardened and grounded ball screw nuts. These have multiple ball recirculations.
 
Due to the special design of the ball screw nuts, the running of the ball screw drives can be adjusted free of clearance.
 
For this the ball screw nuts are fit into the respective clamping blocks and adjusted free of clearance by a setscrew.

The quality assurance of the ball screw drives takes place according to the international standards as well as the internal quality requirements. For this purpose, measurements like ball screw accuracy, pitch accuracy, etc. are done in air-conditioned QA areas at +20° C by using a 3D measuring machine.
 
Ball screws of different lengths with single- or double sided end machining are available on request.

Further accessories such as flange bearings, couplings and connection blocks make the programme perfect.
