The AirTAC AirTAC SDA63X80SH Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 80mm 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 SDA63X80SH is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly space-efficient unit, drastically reducing axial mounting depth compared to traditional round-body actuators. This specific configuration includes an 80 mm stroke, a 20 mm piston rod, and a PT1/4 port.
Equipped with a built-in piston magnet (-S), the body accommodates AirTAC reed or electronic switches along its peripheral grooves for precise position sensing. The -H designation indicates the use of fluororubber (FKM) seals, providing enhanced resistance to elevated temperatures and oily environments. End-of-stroke deceleration is managed by a fixed NBR bumper rather than an adjustable air cushion.

Provides the 1558.6 N push force required to eject dense plastic components from molding fixtures, with FKM seals enduring residual heat and mold release oils.
Utilizes the 80 mm stroke to fold corrugated cardboard flaps on high-speed packaging lines, where the compact riveted body minimizes interference with conveyor frames.
Lifts intermediate machine gates weighing up to 79.4 kg, relying on the built-in magnet to trigger reed or electronic switches for safe upper and lower limit detection.
When sizing this 63 mm bore actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for 2513.3 N at the same pressure. For the SDA63X80SH, a practical safe working load is approximately 935 N (about 60% of the 1558.6 N figure), allowing a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 80 mm stroke, PT1/4 port, female M10x1.5 rod thread, built-in magnet, and FKM seals.
Keep in mind that a standard compact cylinder will not hold a load if air pressure drops or the directional valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke near its limits. If your application requires static holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting 63 mm bore cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-energy cycles, add an external shock absorber. Additionally, it does not hold its load on air loss; the piston drifts when pressure is removed, so an external rod lock or pilot-operated check valve is required for static holding.
