The AirTAC AirTAC SDA80X35H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 35mm 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 SDA80X35H is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. By utilizing a short riveted body that permanently joins the barrel, rear cover, piston, and rod, this unit drastically reduces mounting depth compared to conventional round-body actuators. It delivers a substantial 2513.3 N push force at 0.5 MPa, supported by a hard-anodized 80 mm bore and a robust Ø25 mm piston rod.
This specific SKU includes an H designation, meaning it uses fluororubber (FKM) seals for enhanced thermal stability and oil resistance in demanding environments. End-of-stroke deceleration is handled by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Because this configuration lacks the S option, it has no piston magnet and cannot support magnetic sensing; adding the -S variant enables reed or electronic switches in the body grooves.

Provides high-force ejection of dense plastic parts from injection molding tools, where the short riveted body fits neatly within tight mold clamp spaces.
Drives heavy metal blanks into a stamping press, utilizing the 2513.3 N push force and FKM seals to withstand elevated ambient temperatures and lubricant spray.
Lifts lower pallet layers in a packaging line, handling the 128.1 kg vertical load capacity safely while avoiding the footprint of a large profile cylinder.
When sizing this 80 mm bore actuator, evaluate your force requirements bidirectionally. Stepping down, the SDA63 provides 1558.6 N of push force at 0.5 MPa, which may suffice for lighter payloads. Stepping up, the SDA100 yields 3927 N at 0.5 MPa for heavier machinery demands. For this model, the computed safe working load is approximately 1508 N (about 60% of the 2513.3 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin.
Ensure your ordering essentials match the application: 80 mm bore, 35 mm stroke, PT3/8 port, female M14x1.5 rod-end thread, and FKM seals. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. If your process requires strict position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No adjustable air cushion is available; end stops rely solely on a fixed NBR bumper, so you should slow the approach or add an external shock absorber for high-energy loads. Additionally, this SKU lacks the S magnet option, meaning it cannot host reed or electronic switches without changing to the -S variant.
