The AirTAC AirTAC SDA80X90S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 90mm 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 SDA80X90S is a double-acting single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened axial footprint, saving valuable machine depth where a conventional round-body unit would be too long. The bore is hard-anodized for durability, and this specific configuration includes a built-in piston magnet for position sensing.
Equipped with a 25 mm piston rod and PT3/8 air ports, this model handles a 90 mm stroke within its 130 mm standard limit. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. The integrated magnet supports AirTAC reed or electronic switches fitted into the body grooves.

Drives heavy plastic part ejection plates on large molding presses, utilizing the 2513.3 N extend force to reliably strip dense components from deep cavities.
Pushes robust bearings into automotive gearbox housings on an assembly line, where the short riveted body minimizes overall machine length.
Raises and lowers heavy pallet stops in high-throughput logistics conveyors, depending on the fixed NBR bumper to absorb the kinetic energy at the 90 mm stroke end.
When sizing this unit, stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the massive SDA100 provides 3917 N. For the SDA80X90S, the safe working load is approximately 1508 N (about 60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Ensure you specify the 80 mm bore, 90 mm stroke, PT3/8 port, female M14x1.5 rod thread, and the required -S magnet when ordering. Because a standard double-acting cylinder vents on air loss, the piston will drift if pressure drops; holding a suspended load requires an external rod lock or pilot-operated check valve.
Quick checklist
This 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 force is 513 kgf at 1.0 MPa.
No, the piston will drift if air pressure drops or the valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not act as a locking brake. To maintain position on a suspended load, you must add an external rod lock or a pilot-operated check valve.
