Festo (www.festo.com) has introduced a guided pneumatic swivel module that delivers a versatile rotating drive solution for difficult and larger loads.
Ideal for manufacturing automation, the DSM-HD swivel module eliminates the need for additional guidance or bearing system while seamlessly combining a precision heavy duty bearing with a high performance semi-rotary vane drive to conveniently rotate larger loads via adjustable angle up to 270 degrees.
From a standard compressed air supply of 1.5 to 10 bar, Festo’s DSM-HD pneumatic swivel module delivers significant torque output and accommodates higher moments of inertial and high radial and axial forces. This makes the swivel module suitable for use in demanding applications with offset or large loads as well as in semi- or fully-automatic manufacturing handling and assembly automation that may require the application of added force to its flange during the operation.
Festo offers customers with a selection of six DSM-HD swivel modules, with frame sizes ranging from 12 to 63 and higher load capability than other alternative products. All six modules feature a compact design to facilitate machine integration.
With a caged precision ball bearing race on the periphery, the DSM-HD swivel modules can maintain running accuracy even when subjected to high cantilevered and thrust forces.
Unlike comparable swivel modules, the DSM-HD has been specifically developed to be easier to integrate. For easy control of attachments such as gripper or clamp units, the vane drive’s hollow shaft allows air tubes or electrical cables to be routed through the drive’s body. Meanwhile, the body features three mounting holes on the sides and on the front and rear faces, effectively providing a flexible mounting arrangement that enables the module to be securely fitted in any desired position.
