Linear units with spindle drive

Linear units with spindle drive

Screw driven linear units for simple to even highly dynamic movement applications

Linear actuators with screw drives are the preferred choice when comparably (in comparison to a linear actuator with a timing belt drive) high axial shearing forces and/or the highest levels of accuracy are required.
The carriage is positioned either using a slide guide or a roller guide, depending on the range.
RK linear actuators can also be combined to form multi-axis systems. Standard accessories are available for this purpose. We are happy to help you with the planning and design of a customised system solution.
