Function and application

The DRRD semi-rotary drive is a double-acting twin-piston drive. When the compressed air supply ports
are pressurized reciprocally, two pistons arranged in parallel move in the opposite direction backwards
and forwards. This linear motion is converted through pinions into a swivel motion of the drive shaft.
The end position cushioning is done:
– DRRD-...-P
– DRRD-...-Y9/Y10
– DRRD-...-Y12
The DRRD semi-rotary drive is intended for swivelling effective loads which have to execute a defined
angular movement.
