The control elements are equipped with dovetail guides ("hard-slide" coating) or cross roller guides and are rack & pinion, micrometer or worm driven.
They have minimized backlash and a straightness accuracy within a few microns.
The control elements can be equipped with one or two knobs or without any knob.
Multi-axle systems can be built up using the control elements and corresponding connection elements.
An intermediate plate (B40-RP) is required to attach the tube elements.
