The AirTAC AirTAC SDA40X130 Compact Cylinder | 40mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø40mm bore and 130mm stroke, PT1/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA40X130 is a double-acting single-rod compact cylinder engineered to deliver 628.3 N of push force and 527.8 N of pull force at 0.5 MPa. Its hard-anodized bore and two-way piston seal ensure reliable linear motion within a 30-500 mm/s speed range. Because this specific 130 mm stroke exceeds the standard 120 mm limit, it is produced as a made-to-order unit for extended travel requirements.
The short riveted body design significantly reduces axial mounting depth compared to conventional round-body units, making it highly advantageous for tight machine footprints. Deceleration at the stroke ends is handled by a fixed NBR bumper rather than an adjustable air cushion. This SKU does not include a piston magnet, so it cannot support magnetic position sensing without upgrading to the -S variant.

Actuates a routing flap on a logistics sorting line, utilizing the 130 mm travel to redirect parcels efficiently into secondary chutes.
Provides secondary product ejection from an injection molding press, where the short body length conserves valuable machine footprint behind the tooling.
Drives the mechanical arms that fold top flaps on a case erecting machine, requiring a sturdy 16 mm piston rod to handle repetitive packaging cycles.
When sizing this actuator, evaluate your force margins carefully. Stepping down to the SDA32 yields 402.1 N of push at 0.5 MPa, while stepping up to the SDA50 provides 981.7 N. For the SDA40X130 specifically, the safe working load is approximately 377 N (about 60% of the 628.3 N capacity at 0.5 MPa), which translates to a vertical lift capability of roughly 32 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the end of travel. For suspended or vertical loads that must be held without live pressure, an external rod lock or pilot-operated check valve is required. To order, confirm the 40 mm bore, 130 mm non-standard stroke, PT1/8 port, female rod-end thread (M8x1.25), and the absence of a sensor magnet.
Quick checklist
This 40 mm bore double-acting cylinder generates 628.3 N push and 527.8 N pull at 0.5 MPa, increasing to 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum push force is 128 kgf at 1.0 MPa. The operating pressure range is 0.15-1.0 MPa, with a proof pressure of 1.5 MPa.
No, this cylinder relies on a fixed NBR bumper at each end to decelerate the piston; it is not an adjustable air cushion. Additionally, this specific SKU lacks a piston magnet, meaning it cannot accept AirTAC reed or electronic switches. You would need the -S option for position sensing.
