The AirTAC AirTAC SDA100X45H Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 45mm 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 SDA100X45H is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatic tasks within a minimal axial footprint. By utilizing a short riveted body that integrates the barrel, rear cover, piston, and rod, this unit drastically reduces mounting depth compared to conventional round-body actuators. It provides a robust 3927 N push force at 0.5 MPa, supported by a 32 mm piston rod and PT3/8 air ports.
This specific configuration includes an H designation, meaning it uses fluororubber (FKM) seals for enhanced resistance to higher temperatures and oil exposure. The bore features a hard-anodized interior with a two-way piston seal, while end-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Because this SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing.

Ejects thick metal blanks from progressive stamping dies where the 3927 N push force clears heavy parts, while the compact body fits within tight press tooling.
Raises loaded pallets in packaging lines, utilizing the 200.2 kg vertical lift capacity to elevate goods efficiently without requiring a long profile cylinder.
Pushes large molded plastic components out of heavy industrial injection molds, relying on FKM seals to withstand ambient heat and oil mist.
When sizing this actuator, evaluate your force requirements carefully. If the 3927 N push at 0.5 MPa is excessive, stepping down to the SDA80 yields 2513.3 N, saving physical space. Conversely, the SDA100 represents the largest bore in this series, offering a theoretical maximum push of 801 kgf at 1.0 MPa. A computed insight for this model reveals a safe working load of approximately 2356 N, which equates to a vertical lift capacity of about 200.2 kg when applying a 2:1 safety margin.
Confirm your ordering essentials: a 100 mm bore, 45 mm stroke, PT3/8 ports, female M18x1.5 rod-end thread, and FKM seals. Note that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates the stroke end. To maintain position, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
The SDA100X45H generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push increases to 5497.8 N. The theoretical maximum push is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, this specific SKU does not include the S option, meaning it lacks a piston magnet and cannot trigger AirTAC reed or electronic switches. Additionally, it uses a fixed NBR bumper for end-of-stroke deceleration, which is not an adjustable air cushion, so external shock absorbers may be needed for high-energy loads.
