The AirTAC AirTAC SDA100X40H Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 40mm 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 SDA100X40H is a double-acting single-rod compact cylinder engineered for heavy-duty pneumatic motion within a minimal axial footprint. Utilizing a riveted assembly, it achieves a shorter overall length than conventional round-body actuators, making it ideal for machinery where mounting depth is restricted. This specific SKU features a 100 mm bore, a 40 mm stroke, and a robust 32 mm piston rod, delivering a substantial push force of 3927 N at 0.5 MPa.
Equipped with high-temperature fluororubber (FKM) seals, the -H variant ensures enhanced oil and heat resistance compared to standard NBR components. The unit operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke end. It does not feature an adjustable air cushion, so high-energy cycles may require an external shock absorber. This model lacks a piston magnet and therefore cannot support magnetic sensing.

Provides the high push force needed to eject heavy metal panels from a stamping die, utilizing the compact riveted body to fit within tight press tooling.
Drives large mechanical arms to fold cardboard flaps on industrial palletizers, where the 40 mm stroke and FKM seals withstand heated glue environments.
Applies concentrated force to flatten or align thick steel plates in a fabrication jig, benefiting from the rigid 32 mm rod to resist deflection.
When sizing this actuator, compare its 3927 N push force at 0.5 MPa against adjacent bores. Stepping down, the SDA80 provides 2513.3 N at 0.5 MPa, which may suffice for lighter loads; stepping up is not available as 100 mm is the largest bore in the SDA series. For your ordering essentials, confirm the 100 mm bore, 40 mm stroke, PT3/8 port, female M18x1.5 rod-end thread, and the FKM seal option.
A safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), yielding a vertical lift capacity of roughly 200.2 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the valve is centered—the piston will drift. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 3927 N and the pull force is 3524.9 N. At 0.7 MPa, the push force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the rod near the stroke end and does not act as a lock or brake. To maintain position, an external rod lock or pilot-operated check valve is required.
