Double tube linear units


Simple tube-based spindle axis for manual or electrical position adjustment of your application, e.g. for format, height adjustment or width adjustment on production lines.

Our range includes steel and stainless steel variants in tube diameters ø 18, 30, 40, 50 and 60 mm for a wide variety of tasks.

With these adjusting spindles with hand wheel, a trapezoidal threaded spindle with a guide nut is ball-bearing mounted between two guide tubes, and between two end elements a guide element moves on the double-tube system over the stroke range.

This sturdy design is characterized by its high load capacity combined with maximum torsional rigidity and accuracy and is available in the variants with single guide element or double guide element with connecting plate in the three versions:

Right or left hand thread:
The traversing guide element moves to the left or right by actuating the hand wheel.
Right or left hand thread:
2 guide elements move symmetrically towards or away from each other by actuating the hand wheel.
Split spindle:
2 guide elements move by actuation of one hand wheel per side completely independent of each other, in this case, an additional support element is used centrally between the guide elements.
The order code for single tube linear units is structured as follows:
