The AirTAC AirTAC SDA100X40B 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 SDA100X40B is a double-acting single-rod compact cylinder engineered for heavy-duty tasks, delivering a substantial 3927 N push at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod to minimize axial mounting depth, saving valuable machine footprint where a larger round-body unit would fail to fit. This space efficiency comes without sacrificing power, yielding a theoretical maximum push of 801 kgf at 1.0 MPa.
This specific SKU includes a male M26x1.5 threaded piston rod end for robust mechanical coupling to your load. It operates at 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because it lacks the -S magnet option, it cannot accept AirTAC reed or electronic switches. Buyers should note the 32 mm rod diameter and PT3/8 port size when planning pneumatic connections.

Drives heavy blanking dies and holding fixtures where a 3927 N extend force at 0.5 MPa is required to form steel body panels.
Applies massive leverage to thick sheet metal brakes, utilizing the 32 mm rod and male M26x1.5 thread to securely push bending tools without deflection.
Elevates loaded pallets in packaging lines, safely handling vertical lifts up to 200.2 kg with a 2:1 margin while conserving floor space.
When sizing this actuator, step down to the SDA80 if you need less force, which provides 2513.3 N push at 0.5 MPa. If you require even more power, the SDA100 is the largest bore in this series, offering a maximum 801 kgf push at 1.0 MPa. A safe working load is approximately 2356 N, representing about 60% of the 3927 N figure at 0.5 MPa, which allows for a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Remember that a plain compact cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For secure positioning, integrate an external rod lock or a pilot-operated check valve. To order, confirm the 100 mm bore, 40 mm stroke, PT3/8 port, male M26x1.5 rod thread, and no magnet.
Quick checklist
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa, and 5497.8 N push at 0.7 MPa. The theoretical maximum push is 801 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
No adjustable air cushion is available; it uses a fixed NBR bumper at each end to decelerate the stroke. For high-energy cycles, add an external shock absorber. Additionally, this specific SKU lacks the -S magnet, so it cannot support reed or electronic switches.
