The AirTAC AirTAC SDA40X130S 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 SDA40X130S 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 riveted assembly merges the barrel, rear cover, piston, and 16 mm rod into a highly space-efficient package, drastically reducing axial mounting depth compared to conventional round-body units. This specific configuration includes a built-in piston magnet for position detection and a 130 mm stroke.
Because this model exceeds the standard 120 mm stroke range for a 40 mm bore, it is produced as a non-standard, made-to-order item. The bore is hard-anodized and utilizes a two-way seal, while end-of-travel deceleration relies strictly on fixed NBR bumpers rather than adjustable air cushions. Grooves around the body accept AirTAC magnetic reed or electronic switches, enabling precise end-position confirmation.

Drives a routing flap on a logistics sorting line, utilizing the 130 mm travel to redirect parcels weighing up to 32 kg into secondary chutes at safe operating speeds.
Deploys a folding arm on automated case erecting machinery, where the compact body depth minimizes interference with adjacent packaging tooling.
Indexes lightweight aluminum castings off an assembly pallet, relying on the 628.3 N extend force to overcome sliding friction during transfer.
When sizing this actuator, evaluate your force requirements 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 SDA40X130S, the safe working load is approximately 377 N (60% of the 0.5 MPa push figure), translating to a vertical lift capacity of about 32 kg with a 2:1 safety margin. To order, confirm the 40 mm bore, 130 mm non-standard stroke, PT1/8 port, female M8x1.25 rod thread, and the required -S magnet option.
Keep in mind that a standard double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the load near the stroke end and does not function as a mechanical lock. If your application requires strict load holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 628.3 N and the pull force is 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum push is 128 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
No, the SDA40X130S uses fixed NBR bumpers at each end to absorb impact, not adjustable air cushions. For high-speed or high-energy loads, you should slow the approach speed or add an external shock absorber. Additionally, the -S option provides a magnet for use with AirTAC reed or electronic switches.
