The AirTAC AirTAC SDA40X10SBH 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 SDA40X10SBH is a double-acting single-rod compact cylinder engineered for tight axial spaces. Its riveted body assembly minimizes mounting depth while delivering 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. This specific configuration includes a 10 mm stroke, a male M14x1.5 piston rod end, and an integrated piston magnet for position sensing.
Equipped with fluororubber (FKM) seals, this variant provides enhanced thermal and oil resistance over standard NBR. The 16 mm rod is supported within a hard-anodized bore, and end-stop deceleration is handled by fixed NBR bumpers rather than adjustable pneumatic cushions. To track piston position, the built-in magnet interfaces with reed or electronic switches mounted in the body grooves.

Secures printed circuit boards during routing operations where the 10 mm stroke provides rapid, short-distance clamping without consuming valuable machine Z-axis depth.
Drives a short heat-sealing jaw in packaging lines, utilizing the FKM seals to withstand elevated ambient temperatures near heat elements while delivering 628.3 N of force.
Ejects small machined aluminum parts from a fixture, using the male M14x1.5 rod thread to attach a custom knock-out pin for reliable high-cycle ejection.
Selecting this 40 mm bore involves comparing your output requirements with neighboring sizes. If your application needs less force, the SDA32 provides 402.1 N of push at 0.5 MPa; stepping up to the SDA50 yields 981.7 N. For this SDA40X10SBH, the computed safe working load is roughly 377 N (about 60% of the 0.5 MPa push force), translating to a vertical lift capacity of approximately 32 kg with a 2:1 safety margin. Ensure your ordering essentials match: 40 mm bore, 10 mm stroke, PT1/8 port, male M14x1.5 rod thread, FKM seals, and a sensor magnet.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops 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 machine requires strict load holding on air loss, you must incorporate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed. Position sensing is enabled by the built-in magnet, which works with AirTAC reed or electronic switches fitted into the body grooves.
