The AirTAC AirTAC SDA50X65SH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 65mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X65SH is a double-acting, single-rod compact cylinder engineered to deliver a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. Its short riveted body significantly reduces axial mounting depth compared to round-body units, making it highly advantageous for machinery with tight spatial footprints. The 50 mm bore features a 20 mm piston rod and utilizes PT1/4 ports.
This specific configuration includes the S option for a built-in piston magnet, enabling position detection via AirTAC reed or electronic switches seated in the body grooves. The H designation indicates fluororubber (FKM) seals for enhanced thermal and oil resistance. Deceleration at stroke ends relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should incorporate external shock absorbers for high-energy loads.

Provides the 981.7 N push force required to fold heavy corrugated cardboard flaps on high-speed packaging lines, with FKM seals resisting oily environments.
Uses the 65 mm stroke to eject formed metal parts from small stamping dies, where the short riveted body minimizes interference with the press bed.
Actuates diverter gates on palletizing conveyors, safely handling roughly 50 kg vertical loads while fitting into narrow conveyor framework.
When sizing this unit, consider stepping down to the SDA40, which provides 628.3 N of push force at 0.5 MPa, or moving up to the SDA63, which yields 1558.6 N at the same pressure. Based on the 981.7 N output, the computed safe working load is approximately 589 N (60% capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety margin. Confirm your ordering essentials: 50 mm bore, 65 mm stroke, PT1/4 port, female M10x1.5 rod thread, plus the S magnet and H FKM seal options. Remember that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near the end of travel and does not function as a locking brake. To suspend a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore cylinder generates a push force of 981.7 N and a pull force of 824.7 N at 0.5 MPa. At 0.7 MPa, the push increases to 1374.4 N and the pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa, and the speed range is 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed cycling, you should add an external shock absorber. Because it includes the S magnet option, you can mount AirTAC reed or electronic switches directly into the body grooves for precise position detection.
