Manufacturing ball screws: An exclusive look behind the scenes | isel Germany

The special construction and design of the ball screw nuts allows a BACKLASH-FREE adjustment of the run on the ball bearing screws.

The ball screw nuts from isel Germany are of high quality, precise and abrasion-resistant (hardened and polished). Together with the ball screw spindles, they convert rotations into linear movements most friction-poorly.

The ball screw nut is inserted in the respective clamping block and fastened with a stud screw. The ball screw nuts have several balls paths with internal ball return.

A setscrew on the clamping block makes a clearance-free adjustment of the ball screw spindle's run possible.

The repeatability is less than 0.01 mm at a length of 300 m. To lubricate the linear drive, a greasenipple is fixed on the clamping block. The ball screw spindles are produced with modern machines; they are rolled, hardened and polished.

Our linear drives are technically mature and have stood the test in practice for more than 20 years.
