Products
- High torsional stiffness
- Optimal for unsupported applications
- Support rail for cantilever loads
Due to its cross-section, the bridge module offers the particular advantage that the module can be used as a self-supporting axis without additional stiffeners. Depending on the application, the linear axis can be extended with an additional guide rail, while high accuracy can be achieved through the ball screw at the same time. The guides and spindle are protected against external influences such as dirt, chips etc. by the housing, an extruded aluminium profile, and a cover strip.
The modules are ready-to-install modular linear systems, which can be flexibly configured according to the respective customer requirements. This wide range of options makes it possible to ideally satisfy customer needs. Our bridge modules can be combined with other series to form multi-axis solutions using the standardised adapter parts.
- Unsupported applications
- Cutting systems
- Robotics

1) With regard to service life, we recommend loading the units with max. 20% of the dynamic load rating
2) Higher requirements on request
3) Larger strokes possible with composite base profiles
4) Depending on the speed characteristic value or the critical speed
Attention: Specified values are empirically determined and vary depending on the application.
The values are maximum values.
