The AirTAC AirTAC SDA50X130SH Compact Cylinder | 50mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø50mm bore and 130mm 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 SDA50X130SH is a double-acting, single-rod compact cylinder engineered to deliver 981.7 N of push force and 824.7 N of pull force at 0.5 MPa. The riveted unibody design integrates the barrel, rear cover, and piston to drastically reduce axial mounting depth, making it highly effective for machinery where a standard round-body unit would protrude too far. Equipped with a 20 mm piston rod and PT1/4 ports, it handles a 130 mm stroke while operating at speeds between 30 and 500 mm/s.
This specific configuration includes an -S piston magnet for direct mounting of AirTAC reed or electronic switches along the body grooves, plus an -H fluororubber (FKM) seal variant for enhanced thermal and oil resistance. End-stopping relies on a fixed NBR bumper that decelerates the piston near stroke limits; because this is not an adjustable air cushion, high-energy cycles should utilize an external shock absorber or a slowed approach speed.

Pushes medium-weight cartons off a high-speed sorting line, utilizing the 130 mm stroke to clear adjacent lanes efficiently.
Raises a lower-tier palletizing gate with a safe 50 kg vertical lift capacity, saving vertical headroom via the short riveted body.
Maintains precise tension on packaging film feeds where the FKM seals withstand elevated ambient temperatures near heat-sealing jaws.
When sizing this actuator, stepping down to the SDA40 yields 628.3 N of push at 0.5 MPa, while stepping up to the SDA63 provides 1558.6 N. Based on the 981.7 N output at 0.5 MPa, a safe working load is approximately 589 N (60% capacity), translating to a vertical lift capability of about 50 kg with a 2:1 safety margin. To finalize your order, confirm the 50 mm bore, 130 mm stroke, PT1/4 porting, female M10x1.5 rod thread, the -S magnet, and the -H FKM seal option.
Keep in mind that a standard double-acting cylinder will not hold a load if air pressure drops or the directional valve is centered. The piston will drift, and the fixed bumper only decelerates it near the end of travel rather than locking it. If your application requires strict position holding, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 50 mm bore double-acting cylinder generates 981.7 N push and 824.7 N pull at 0.5 MPa. At 0.7 MPa, push increases to 1374.4 N and pull to 1154.5 N. The theoretical maximum push is 200 kgf at 1.0 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke at the end caps; it does not act as a brake. You must add an external rod lock or pilot-operated check valve to hold loads securely.
