The AirTAC AirTAC SDA100X50SB 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 SDA100X50SB is a double-acting, single-rod compact cylinder engineered for heavy-duty positioning within a minimal axial footprint. Utilizing a riveted body assembly, it achieves a remarkably short overall length compared to conventional round-body units, saving valuable machine mounting depth. At 100 mm bore, it generates 3927 N of push force and 3524.9 N of pull force at 0.5 MPa, operating efficiently between 30-500 mm/s.
This configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves, plus a male M26x1.5 piston rod thread (-B) for robust load coupling. The internal end-stops rely on a fixed NBR bumper to decelerate the stroke rather than an adjustable air cushion. Because the piston drifts when air pressure is lost, an external rod lock or pilot-operated check valve is required to safely hold a suspended load.

Drives heavy metal blanks into large mechanical presses, utilizing the 5497.8 N extend force at 0.7 MPa to overcome material friction.
Elevates loaded pallets in compact packaging cells where axial space is restricted, relying on the 200.2 kg vertical lift margin.
Applies sustained clamping pressure on thick steel plates during industrial bending operations via the robust M26x1.5 male rod end.
Selecting the SDA100X50SB provides massive thrust in a tight envelope, delivering a safe working load of roughly 2356 N (about 60% of its 3927 N push at 0.5 MPa) and a vertical lift capacity of approximately 200.2 kg with a 2:1 safety margin. If your application requires less force, the SDA80 offers 2513.3 N at 0.5 MPa; as the largest standard bore in the series, stepping up beyond 100 mm would require a different body architecture. Ensure you specify the PT3/8 air ports, the 50 mm stroke, the male M26x1.5 rod end, and the integrated magnet when submitting your RFQ.
Quick checklist
This 100 mm bore model uses PT3/8 air ports. It generates 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum push of 801 kgf at 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, not an adjustable cushion. Additionally, it does not hold its load if air is lost; the piston will drift. For load holding, you must add an external rod lock or pilot-operated check valve.
