Each task has the right to be solved best

Linear units – your solution is included

There is nearly no area within the fields of automation and machine construction where linear units are not used.  It starts with simple positioning tasks which are possibly very seldom used and ends with highly complex multiple systems of high accuracy and with high dynamics.  Each task is different. And each task shall contain the technically experienced solution under consideration of economic aspects.

Diversity for the best solution
The wide selection of RK linear units has been developed referring to different customer applications. The solution which was called a “Special application” last year is now a standard module for an attractive price and fast availability.  This increases the chance that an RK linear unit is already available for your specific application.

Competency and experience
Linear units belong to the products that need the most advisory assistance because their layout depends on the task and the investment framework.  To find out the type and size of the best suitable linear unit is a challenge we would like to take up. Our specialists are best skilled, competent, and have a wealth of experience which our customers rate highly. 

Task specific solutions
What would a linear unit be without its wide selection of suitable accessories? So the following also applies: From the simplest positioning by hand wheel to the dynamics controlled by servomotor using high performance control technologies and sensors.


Linear spindle units

The linear spindle units feature high longitudinal load bearing capacity. Tapered thread spindles with self inhibition as well as ball-type linear drives of high precision are provided for the appropriate positioning tasks.

Timing belt - linear units

Dynamic tasks can nearly be solved without them.  Toothed-belt linear units are fast and intended for inversion mode with short cycle times.  The timing belts HD- and GT- quality reach highest precision when used for positioning jobs.

Toothed rack - linear units

In case of long strokes, spindles and timing belts cannot be utilized efficiently.  This is the situation where the toothed rack accomplishes its purpose. Maximal 50 metres can be realised without lower accuracy.

Sliding and rolling guide

These linear units which are not driven are the ideal supplement for the driven units, e.g. if a supporting axle is required due to an eccentric load.

Heavy duty linear unit D-Line

Heavy loads have only be moved by linear axes made of steel components until now. The high dead weight, however, must often be moved too. This is unfavourable for the dynamics and the necessary motor size.
D-Line combines dynamics and the loading capacity with low dead weight and sounds the bell for a new generation in the filed of automation.

Controls and motors

There is also a choice of positioning controls and motors as addition to the program of linear units and this forms the basis for the development of complete system solutions.
