Festo 2 Finger Double Action Pneumatic Gripper, DHRS-25-A, Radial Gripping Type

This double-action pneumatic gripper from Festo has a two-finger design. It's ideal for grasping or holding parts in pneumatic systems. Applications include manufacturing processes such as plastic moulding and sensor manufacturing as well as usage in the robotics and biotech industries. The jaws of this radial gripper can apply a great deal of force, up to a maximum of 75 N. They are constructed from extremely tough high-alloy steel, with the housing formed from wrought aluminium alloy for high tensile strength.

• Double gripping action
• Radial type
• Maximum operating pressure of 8 bar
• Total gripping torque at 6 bar (opening) of 233 Ncm
• Total gripping torque at 6 bar (closing) of 215 Ncm
• Weight of 270 g

• All radial grippers in Festo's DHRS series can be used as both double-acting and single-acting grippers, for greater flexibility
• Lateral gripper support for high-torque loads
• Designed with a self-centring mechanism
• Internal fixed flow control means no need for external flow control in almost all applications
• Wide range of adaptation options on the drives
• Suitable for both external and internal gripping

The Festo radial gripper DHRS-25-A indicated opening and closing times [Ms] were measured at room temperature at an operating pressure of 6 bar with the gripper horizontally mounted and without additional gripper fingers (mean values shown). The grippers must be throttled for greater applied loads. Opening and closing times must then be adjusted accordingly.
