Drive Elements - Ball Screws
Drive elements from isel: high travel and positioning accuracy
Drive elements in the form of ball screw nuts and ball screw spindles are part of isel’s core competence: Over 1.000.000 units sold within 25 year are indicative of our know-how. isel ball screws are high-quality, precise, wear-resistant and made in Germany. Isel driving elements are manufactured on state-of-the-art machines in a rolled execution and then hardened and polished. As a rolled version they are much more favorable priced than ground ball screws and yet suitable for many applications.
isel drive elements are produced in a vast range of lengths, diameters and screw pitches. Through the combination of ball screw and ball nut they work effective and with very low friction.
The special construction and design of the ball screw nuts allows a backlash-free adjustment of the run on the ball bearing screws.
For this purpose the ball screw nuts are fastened on the respective clamping blocks and adjusted backlash-free using an adjusting screw.
Ball screws spindles from isel are manufactured according to DIN 69051, Part 3, Tolerance Class 7 and available in various lengths with single or double sided end machining.
Ball screw nuts from isel can be delivered with single path return and complete ball return. The special design and construction allows a free setting of the barrel at the ball screws.
Flange bearings from isel are housing units in duplicate - either with the spindle bearing drive side or bearing of spindle-drive side and non-locating spindle. Consistent with the spindle, they are available in various diameters.
Bearing blocks from isel consist of an aluminium profiles according to DIN EN 12020-2 and can be fixed universal. They are used for adaptation of the motor and bearing flange.
isel clamping blocks are for base and flange securing and are made of burnished steel. They are available for ball screw spindles with a diameter of 16 mm and 25 mm.
Shaft couplings from isel connect the drive and bearing support. They serve to balance the axial shaft offset, reduce torque and rotational speed bumps and reduce the expansion of the structure-borne sound.
