The AirTAC AirTAC SDA100X5SB 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 SDA100X5SB is a double-acting, single-rod compact cylinder engineered for high-force duties within a minimal axial footprint. By utilizing a riveted assembly that merges the barrel, rear cover, piston, and rod, this unit achieves an exceptionally short overall length compared to conventional round-body designs. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, operating efficiently at speeds between 30-500 mm/s.
This specific configuration includes a built-in piston magnet (-S) for direct compatibility with AirTAC reed or electronic switches, fitting neatly into the body's peripheral grooves. The -B option equips the 32 mm rod with a male M26x1.5 thread, providing a robust mechanical coupling for your load. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, effectively decelerating the piston near stroke extremes without requiring external valving.

Drives a short 5 mm impact stroke in automated sheet metal stamping, delivering immediate 3927 N force to form thick gauge components.
Provides a compact, high-thrust ejection mechanism for heavy industrial molds, utilizing the male M26x1.5 rod end to securely push dense parts out of the cavity.
Applies controlled clamping pressure for structural rivet installation, where the fixed NBR bumper absorbs the sudden shock of the riveting cycle.
Selecting this 100 mm bore model provides substantial thrust, but evaluating adjacent sizes ensures optimal sizing. Stepping down, the SDA80 offers 2513.3 N push at 0.5 MPa; stepping up is not available as this is the largest bore in the SDA series. When sizing your application, a safe working load is approximately 2356 N (about 60% of the 3927 N figure), allowing a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Confirm your ordering essentials: 100 mm bore, 5 mm stroke, PT3/8 port, male M26x1.5 rod thread, and the integrated magnet.
Quick checklist
This 100 mm bore double-acting cylinder provides a push force of 3927 N and a pull force of 3524.9 N at 0.5 MPa. At 0.7 MPa, the push force is 5497.8 N and the pull force is 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
No, a plain SDA cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the rod near the stroke end and does not act as a lock or brake. To maintain a vertical load without live pressure, you must install an external rod lock or a pilot-operated check valve.
