The AirTAC AirTAC SDA100X5S Compact Cylinder | 100mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø100mm bore and 5mm 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 SDA100X5S is a double-acting single-rod compact cylinder engineered for high-force duties within a minimal axial footprint. Delivering a substantial 3927 N push at 0.5 MPa, it relies on a short riveted body that joins the barrel, rear cover, piston and rod to save mounting depth where round-body units fail to fit. The 100 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable operation.
Equipped with a built-in piston magnet (-S), this unit supports AirTAC magnetic reed or electronic switches via body grooves for precise position detection. It uses a fixed NBR bumper at each end to decelerate the stroke, meaning operators must slow the approach or add external shock absorbers for high-energy cycles. With a 32 mm rod and PT3/8 ports, it handles heavy loads without occupying excessive machine space.

Uses the 3927 N extend force to knock heavy metal blanks out of stamping dies quickly within a tight press footprint.
Raises heavy mold halves vertically, safely managing a 200.2 kg dynamic load during the brief 5 mm opening sequence.
Provides high clamping pressure on thick steel assemblies, relying on the 32 mm rod to resist deflection during the weld cycle.
When sizing this model, evaluate your force requirements carefully. Stepping down, the SDA80 provides 2513.3 N push at 0.5 MPa, which may suffice for lighter loads. Stepping up is not possible as 100 mm is the largest bore in the SDA series, so for demands exceeding 3927 N you would need multiple cylinders or a different format. The computed safe working load is approximately 2356 N (about 60% of the 0.5 MPa figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 margin.
Confirm your ordering essentials: 100 mm bore, 5 mm stroke, PT3/8 port, built-in magnet (S), and female M18x1.5 rod-end thread. Remember that a plain compact cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. For suspended or vertical loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
This double-acting cylinder 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 force is 801 kgf at 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. For high-speed cycles, add an external shock absorber. Additionally, it does not hold its load on air loss; the piston drifts, so an external rod lock or pilot-operated check valve is required for position holding.
