The AirTAC AirTAC SDA100X50SH 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 SDA100X50SH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, it achieves an exceptionally short overall length compared to conventional round-body units. At 100 mm bore, it generates a substantial 3927 N push and 3524.9 N pull force at 0.5 MPa. This specific configuration includes an FKM fluororubber seal for enhanced thermal and oil resistance, operating reliably across a 30-500 mm/s speed range.
Despite its high output, the unit remains space-efficient. The hard-anodized bore houses a two-way piston seal, while integrated grooves around the body accept AirTAC reed or electronic switches via the built-in S magnet. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycles. The 32 mm piston rod terminates in a female M18x1.5 thread, and air connections use PT3/8 ports.

Supplies the heavy stripping force needed to eject dense plastic parts from injection molding platens, where the 3927 N push at 0.5 MPa easily breaks the vacuum grip.
Provides steady clamping pressure for bending thick sheet metal in press brakes, utilizing the 3524.9 N pull force to hold dies securely during deformation.
Drives the vertical lifting arms in automated palletizing cells, taking advantage of the compact riveted body to minimize axial mounting depth in tight machine cells.
Selecting this 100 mm bore model provides a theoretical maximum push of 801 kgf at 1.0 MPa, yielding a safe working load around 2356 N (roughly 60% of the 3927 N figure at 0.5 MPa) and a vertical lift capacity of 200.2 kg with a 2:1 safety margin. If your application requires less force, the neighboring SDA80 offers 2513.3 N push at 0.5 MPa; as the largest standard size, stepping up beyond 100 mm would require a different cylinder family. When ordering, confirm the 50 mm stroke, PT3/8 port, female M18x1.5 rod thread, FKM seals, and the required magnetic switches.
Because this is a double-acting cylinder, it will not hold a load if air pressure drops or the control valve centers—the piston will drift, and the fixed NBR bumper only decelerates near the stroke end rather than locking it. For vertical or suspended loads that must remain stationary during a loss of pressure, incorporate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This double-acting 100 mm bore cylinder generates a push of 3927 N and a pull 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 1.0 MPa operating pressure limit, with a proof pressure of 1.5 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 does not hold position on air loss; the piston drifts if pressure drops. For high-speed energy absorption, add external shock absorbers, and use a pilot-operated check valve for load holding.
