The AirTAC AirTAC SDA63X130S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm 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 SDA63X130S is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its short riveted body design significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies. This 63 mm bore model includes a built-in piston magnet for position detection.
The unit features a 20 mm piston rod, a PT1/4 air port, and a 130 mm stroke. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy loads. The internal magnet supports AirTAC reed or electronic switches mounted in the body grooves.

Drives ejection plates in plastic injection molding machines where the 1401.5 N retract force clears finished parts, utilizing the short body to fit within tight mold clamping spaces.
Pushes heavy pallets on packaging lines using the 2182.1 N extend force at 0.7 MPa, with the 130 mm stroke providing sufficient travel to redirect items onto secondary tracks.
Actuates lightweight vertical lifting gates on automated machinery, lifting loads up to 79.4 kg with a 2:1 margin while the fixed NBR bumper softens the end stop.
When sizing this model, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80 for 2513.3 N at the same pressure. The 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (about 60% capacity) and a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin. Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered; maintaining vertical loads requires an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 130 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required -S magnet option.
Quick checklist
This double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa, and 2182.1 N push at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s and a proof pressure of 1.5 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not a field-adjustable air cushion. Additionally, it cannot hold a load if air is lost; the piston will drift. An external rod lock or pilot-operated check valve is required for position holding.
