The AirTAC AirTAC SDA40X10SH 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 SDA40X10SH is a double-acting, single-rod compact cylinder engineered for minimal axial mounting depth. By utilizing a riveted assembly that joins the barrel, rear cover, and piston, it achieves a remarkably short overall length where round-body units cannot fit. Delivering 628.3 N of push force at 0.5 MPa, this 40mm bore model is built for rigorous pneumatic duties.
This specific configuration includes a 10mm stroke, a 16mm piston rod, and PT1/8 ports. The -H option specifies fluororubber (FKM) seals for enhanced thermal and oil resistance, while the -S option equips a built-in piston magnet for position detection. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.

Applies 628.3 N of precise lateral force to align circuit boards on an SMT conveyor prior to component placement.
Utilizes the short 10mm stroke and FKM seals to swiftly tuck packaging flaps on high-speed lines exposed to misted lubricants.
Pushes small metal blanks out of a progressive die using its 16mm rod, relying on the fixed NBR bumper to absorb the sudden end impact.
When sizing this actuator, consider stepping down to the SDA32, which yields 402.1 N of push at 0.5 MPa, or moving up to the SDA50, which provides 981.7 N at the same pressure. For the SDA40X10SH, a safe working load is approximately 377 N (about 60% of the 628.3 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 32 kg with a 2:1 safety margin. To order, confirm the 40mm bore, 10mm stroke, PT1/8 port, female M8x1.25 rod thread, plus the S magnet and H FKM seal options. Note that a plain compact cylinder drifts if air pressure is lost; holding a suspended load requires an external rod lock or 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, push is 879.6 N and pull is 738.9 N. The theoretical maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion; for high-speed operations, you should add an external shock absorber. The built-in magnet (-S) allows tracking via an AirTAC reed or electronic switch mounted in the body grooves.
