The AirTAC AirTAC SDA50X100BH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 100mm stroke, PT1/4 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA50X100BH is a double-acting, single-rod compact cylinder engineered to deliver a robust 981.7 N push force at 0.5 MPa. Its riveted body assembly keeps axial dimensions minimal, conserving valuable machine footprint where a conventional round-body actuator would be too long. This specific SKU is configured with a male M18x1.5 piston rod thread for direct load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The unit operates at speeds between 30-500 mm/s and relies on a fixed NBR bumper at each end to decelerate the stroke. Because this configuration lacks the -S magnet option, it cannot support AirTAC reed or electronic switches. The 100 mm stroke moves a 20 mm diameter rod through a hard-anodized 50 mm bore, fed by PT1/4 ports.

Drives the folding mechanism on continuous packaging lines, using the 100 mm stroke and 981.7 N force to swiftly erect heavy cardboard carton flaps.
Pushes loaded pallets sideways onto adjacent roller tracks, where the compact riveted body minimizes interference in tight transfer zones.
Mounts directly to molding machinery via the male M18x1.5 rod to eject plastic parts, leveraging FKM seals to withstand ambient heat.
Selecting this 50 mm bore provides a safe working load of roughly 589 N (about 60% of the 981.7 N push at 0.5 MPa), which translates to a vertical lift capacity of approximately 50 kg with a 2:1 safety margin. If your application requires less force, stepping down to the SDA40 yields 628.3 N at 0.5 MPa; conversely, scaling up to the SDA63 provides 1558.6 N at 0.5 MPa. Ensure you specify the 100 mm stroke, PT1/4 port, male M18x1.5 rod, and FKM seals when ordering.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered—the piston will drift. The fixed rubber bumper only decelerates the load near the stroke end and acts as neither a lock nor a brake. To maintain a vertical load without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa, increasing to 1374.4 N push and 1154.5 N pull at 0.7 MPa. The theoretical maximum push force is 200 kgf at 1.0 MPa.
No, this specific SKU lacks the -S piston magnet, so it cannot trigger AirTAC reed or electronic switches. Additionally, it uses fixed NBR bumpers rather than adjustable air cushions, so external shock absorbers may be needed for high-energy loads.
