The AirTAC AirTAC SDA40X10S Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 10mm 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 SDA40X10S is a double-acting, single-rod compact cylinder engineered for tight axial spaces. Operating at 0.5 MPa, it generates 628.3 N of push force and 527.8 N of pull force, making it a robust choice for short-stroke actuation. The riveted unibody design drastically reduces overall length compared to conventional round-body units, saving valuable machine footprint.
This specific configuration 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 cushion, meaning operators should control approach speeds externally for high-mass loads. It features a 16 mm piston rod, a female M8x1.25 rod-end thread, and PT1/8 air ports.

Provides 628.3 N of clamping force at 0.5 MPa to secure aluminum engine blocks during CNC milling, utilizing the 10 mm stroke to lock parts rapidly without consuming valuable machining envelope.
Deploys the 16 mm rod in packaging lines to tuck corrugated carton flaps prior to sealing, where the short 10 mm stroke and compact riveted body fit neatly within tight conveyor side-guides.
Pushes molded plastic parts out of injection molds using the 527.8 N retract pull force, while the integrated magnet triggers a solid-state switch to confirm ejection completion.
Selecting this 40 mm bore involves balancing your force requirements: stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For this SDA40X10S, the 628.3 N output at 0.5 MPa translates to a safe working load of roughly 377 N (about 60% capacity) or a vertical lift capability of approximately 32 kg with a 2:1 safety margin.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only absorbs end-stop impact and acts as neither a lock nor a brake. To secure a suspended load during an outage, incorporate an external rod lock or a pilot-operated check valve. When ordering, confirm the 10 mm stroke, PT1/8 port, female rod thread, and the required -S magnet for sensing.
Quick checklist
This double-acting cylinder delivers a push force of 628.3 N and a pull force of 527.8 N at 0.5 MPa. At 0.7 MPa, push increases to 879.6 N. The theoretical maximum push is 128 kgf at 1.0 MPa. It operates on filtered air between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and supports speeds from 30-500 mm/s.
No adjustable air cushion is featured; instead, a fixed NBR bumper absorbs impact at the stroke ends. For high-energy cycles, slow the approach speed or add external shock absorbers. Additionally, the cylinder cannot hold a load if air pressure drops—it will drift. Use an external rod lock or pilot-operated check valve if position holding is required.
