The AirTAC AirTAC SDA100X50S Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 50mm 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 SDA100X50S is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted body assembly, it saves mounting depth where a conventional round-body unit would fail to fit. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, operating at speeds of 30-500 mm/s.
This specific configuration includes a built-in piston magnet (the S option) for position detection using an AirTAC reed or electronic switch seated in the body grooves. The 32 mm piston rod features an M18x1.5 female thread, while the PT3/8 air ports supply ample flow for the 50 mm stroke. End-of-travel deceleration is handled by a fixed NBR bumper, which reduces impact shock but is not an adjustable air cushion.

Provides the heavy push force needed to eject thick metal blanks from a stamping press die, utilizing the 3927 N extend capability at 0.5 MPa.
Raises lowerator forks handling loaded pallets, where the 200.2 kg vertical lift capacity with a 2:1 margin safely manages heavy goods transfer.
Breaks loose large molded plastic parts from heavy injection tooling, taking advantage of the 32 mm rod and massive 3524.9 N retract force.
Selecting this 100 mm bore model provides a massive 801 kgf theoretical maximum output at 1.0 MPa. If your application requires less force, stepping down to the SDA80 yields 2513.3 N of push at 0.5 MPa; as the largest standard size, there is no larger SDA option, so loads exceeding this class require a different cylinder architecture. With a safe working load around 2356 N (roughly 60% of the 0.5 MPa push figure), it can vertically lift approximately 200.2 kg with a 2:1 safety margin.
When ordering, confirm the 100 mm bore, 50 mm stroke, PT3/8 porting, and the female rod-end thread. Because the SDA100X50S includes the S option, it arrives ready for magnetic sensing. Note that a standard compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates the stroke end rather than locking the load. For vertical or suspended loads, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
The SDA100X50S generates a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push is 801 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it cannot hold a load if air is lost or the valve is centered; the piston will drift. An external rod lock or pilot-operated check valve is required for position holding.
