The AirTAC AirTAC SDA40X60S Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 60mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X60S is a double-acting single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its riveted body construction significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. The 16 mm piston rod utilizes a female M8x1.25 thread for straightforward load coupling.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or add external shock absorbers for high-energy loads. The bore accepts a PT1/8 port and supports a standard stroke length of 60 mm.

Drives the mechanical arms that tuck minor product flaps on high-speed packaging lines, utilizing the 60 mm stroke to clear the path for the main sealer.
Actuates routing gates on distribution conveyors, where the 628.3 N push force easily redirects heavy goods onto secondary chutes.
Ejects formed sheet metal brackets from small die sets, taking advantage of the short riveted body to fit within tight press enclosures.
When sizing this 40 mm bore, stepping down to the SDA32 yields 402.1 N of push force, while stepping up to the SDA50 provides 981.7 N at 0.5 MPa. For this SDA40X60S configuration, the safe working load is approximately 377 N (about 60% of the 628.3 N figure), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. Confirm your ordering essentials: 40 mm bore, 60 mm stroke, PT1/8 port, female rod thread, and the -S magnet.
Keep in mind 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 it. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, the push force is 879.6 N and the pull force is 738.9 N. The theoretical maximum push force is 128 kgf at 1.0 MPa.
It relies on a fixed NBR bumper to decelerate the piston at the stroke ends, which is not an adjustable air cushion; high-speed applications may need external shock absorbers. The -S option provides a built-in magnet for tracking position with AirTAC reed or electronic switches.
