The AirTAC AirTAC SDA80X20H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 20mm 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 SDA80X20H is a double-acting single-rod compact cylinder engineered for heavy-duty operations within restricted axial mounting spaces. Utilizing a riveted body assembly, it significantly reduces overall length compared to conventional round-body units. At 80mm bore, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa. This specific H-series configuration incorporates fluororubber (FKM) seals, elevating resistance to high ambient heat and oil contamination.
The unit features a robust 25mm piston rod and PT3/8 air ports. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling. This SKU is supplied without a piston magnet, so it cannot directly host AirTAC reed or electronic switches. Theoretical maximum thrust reaches 513 kgf at 1.0 MPa.

Drives short-stroke ejection pins inside tight mold platen recesses where the 2513.3 N output clears finished plastic components efficiently.
Actuates upper die clamps on heavy metal fabrication machinery, utilizing the FKM seals to withstand elevated shop-floor temperatures.
Indexes heavy conveyor pallets vertically, safely handling loads near 128 kg with a 2:1 safety factor during automated transfer cycles.
When sizing this actuator, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDA100 provides 3927 N at the same pressure. Based on the 2513.3 N output at 0.5 MPa, a safe working load is approximately 1508 N (about 60% of capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80mm bore, 20mm stroke, PT3/8 porting, female M14x1.5 rod thread, and the FKM seal option. Note that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only slows the piston near stroke end and does not function as a locking brake. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This 80mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, alongside 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the functional speed range is 30-500 mm/s.
End-of-stroke deceleration relies on a fixed NBR bumper, which is not a field-adjustable air cushion; for high kinetic energy loads, add an external shock absorber. Because this specific SKU lacks the -S magnet option, it cannot support AirTAC reed or electronic switches. If position feedback is required, select the SDA80X20HS variant instead.
