The AirTAC AirTAC SDA80X50SH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X50SH is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. By utilizing a short riveted body that integrates the barrel, rear cover, piston, and rod, it drastically reduces mounting depth compared to conventional round-body units. At 80 mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. This specific configuration includes an FKM fluororubber seal for heightened thermal and oil resistance, alongside a built-in piston magnet for position sensing.
The unit features a 25 mm piston rod and PT3/8 air ports, utilizing a fixed NBR bumper at each stroke end to decelerate the payload. Because this bumper is rigid and not an adjustable air cushion, operators should slow the approach speed or mount an external shock absorber for high-energy cycles. The male M22x1.5 rod-end thread provides a robust coupling point, though side loading must be strictly avoided on this compact rod to prevent premature wear.

Provides robust 2513.3 N push force to eject heavy formed metal panels from progressive stamping dies, utilizing the male M22x1.5 thread for secure tooling attachment.
Folds corrugated cardboard flaps on high-speed packaging lines where the compact riveted body saves valuable axial space within the conveyor framework.
Lifts heavy injection molding platens vertically, handling the 128.1 kg payload capacity safely while the FKM seals withstand elevated ambient shop temperatures.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push force at 0.5 MPa, or moving up to the SDA100, which provides 3927 N at the same pressure. The SDA80X50SH achieves a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials match the bore, 50 mm stroke, PT3/8 port, male M22x1.5 rod thread, magnet, and FKM seal requirements.
A standard double-acting cylinder will not hold its position if air pressure drops or the control valve centers; the piston drifts, and the fixed bumper only decelerates near the stroke end rather than locking it. If your application must maintain a load without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, alongside 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 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 spans 30-500 mm/s.
This model uses a fixed NBR bumper at each end to decelerate the piston near the stroke extremes. It is not an adjustable air cushion, so for high-speed or high-energy loads, you should add an external shock absorber or reduce the approach velocity. Additionally, the built-in magnet allows tracking via an AirTAC reed or electronic switch.
