The AirTAC AirTAC SDA80X55S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 55mm 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 SDA80X55S is a double-acting, single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted assembly merges the barrel, rear cover, and piston to deliver a robust 2513.3 N push force at 0.5 MPa, extending to 3518.6 N at 0.7 MPa, without the lengthy mounting depth of conventional round-body units. The 80 mm bore houses a 25 mm hard-chrome rod and features a hard-anodized inner wall to reduce friction wear.
This specific configuration includes the -S option, meaning a built-in piston magnet enables position detection via an AirTAC reed or electronic switch seated in the body grooves. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, ensuring reliable deceleration that may require an external shock absorber under high kinetic loads. Air connections use a PT3/8 port, and the female M14x1.5 rod end thread handles direct load coupling.

Drives heavy press dies for automotive body panel forming, utilizing the 2513.3 N push force to shape high-strength steel blanks reliably.
Elevates loaded pallets in packaging lines, where the 128.1 kg vertical lift capacity and 55 mm stroke securely index goods to the next conveyor tier.
Pushes thick-sectioned molded plastic parts out of heavy tooling, depending on the 25 mm rod rigidity to withstand ejection resistance without side-load damage.
Selecting this 80 mm bore unit provides a theoretical maximum push of 513 kgf at 1.0 MPa, translating to a safe working load of roughly 1508 N (about 60% of the 0.5 MPa figure) or a vertical lift capacity of approximately 128.1 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa; conversely, upgrading to the SDA100 provides 3927 N at 0.5 MPa for heavier demands. Confirm your ordering essentials: 80 mm bore, 55 mm stroke, PT3/8 port, female rod thread, and the integrated -S magnet.
Keep in mind that a standard double-acting cylinder does not hold its position when air pressure is lost or the directional valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a mechanical lock. If your machinery must maintain a suspended load during an emergency stop or pressure drop, incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
This double-acting 80 mm bore cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and functions at speeds of 30-500 mm/s.
It uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion; high-speed applications may need external shock absorbers. Because it includes the -S magnet option, you can mount an AirTAC reed or electronic switch directly into the body grooves for precise end-of-stroke detection.
