1187957
Swivel/gripper unit HGDS-PP-12-YSRT-A-B
The Festo part number 1187957 is a double-acting industrial component featuring a structural design combining a quarter turn actuator with a parallel gripper and gripper actuator across two gripper jaws. It operates at a pressure of 3 bar to 8 bar, offering a size 12 specification, a stroke of 2.5 mm per gripper jaw, and a swivel angle adjustment range of 0 deg to 210 deg with a 210 deg swivel angle. This unit includes self-adjusting shock absorbers at both ends with metal fixed stops, a 1 mm cushioning adjustment range, pneumatic shock absorber cushioning at both ends, and position sensing via proximity switch on both the pneumatic gripper and quarter turn actuator. Performance metrics include a max gripper jaw angular play ax, ay of 0.1 deg, max gripper jaw backlash Sz of 0.02 mm, pneumatic gripper repetition accuracy of 0.01 mm, swivel angle repetition accuracy of 0.02 deg, and quarter turn actuator fine tuning of -2.5 deg in any mounting position. Please submit the exact part number, quantity, and application requirements for a formal quotation.
