Grippers are designed for continuous performance, in the harshest conditions, dust, sand, chips, etc.
All grippers can be pressurized and are maintenance-free for more than 3,000,000 cycles in any conditions.Three classes of this kind of grippers are made
RTF – With ISO standard flanges to connect directly on the robot to 200kg payload. Actuation of gripping stroke via hydraulic pistons is available.
