Festo launches guided pneumatic swivel module

Festo has launched a guided pneumatic swivel module for manufacturing automation that provides a versatile rotating drive solution for larger and difficult loads.

The new DSM-HD swivel module combines a high performance semi-rotary vane drive with a precision heavy duty bearing to rotate larger loads through adjustable angles up to 270 degrees - accurately and without any need for additional bearings or guidance systems.



Festo has also simplified application matching. When selecting a swivel module and deciding how to mount it, machine designers need to evaluate a number of application-specific factors. These include the axial and radial forces acting on the module, the torque required to start the load moving, the mass moment of inertia (which is particularly critical for the stops and cushioning of rotating masses), and the required end-position accuracy.

It can be hard to visualise or estimate mass moment of inertia and time-consuming to calculate manually, so Festo has developed software to help designers tackle this task quickly and easily. Available free of charge, the inertia calculation software can be downloaded from the engineering tools support portal on Festo's website.



Capable of generating significant torque output from a standard (1.5 to 10 bar) compressed air supply, Festo's DSM-HD swivel module can accommodate high axial and radial forces, as well as higher moments of inertia, making it ideal for demanding applications with large or offset loads.

The module is especially suitable for use in fully- or semi-automatic manufacturing handling and assembly automation, where additional force might be applied to its flange during the operational cycle.
