The AirTAC AirTAC SDA63X5H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 5mm 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 SDA63X5H is a double-acting, single-rod compact cylinder engineered for very short 5mm strokes. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. The riveted body design significantly reduces axial mounting depth compared to round-body units, fitting high-force actuation into tight machine footprints. This H-spec variant utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
The 63mm bore features a 20mm piston rod and PT1/4 air ports. Instead of an adjustable air cushion, it relies on a fixed NBR bumper at each end to decelerate the stroke. Because this SKU lacks the S option, it has no piston magnet and cannot support magnetic sensing; adding the -S code enables reed or electronic switch compatibility via the body grooves.

Provides high-force 1558.6 N workholding for machining centers, utilizing the 5mm stroke to lock heavy cast iron blocks firmly against locator stops.
Delivers a short 5mm ejection punch for plastic parts, with FKM seals enduring the ambient heat radiating from the mold tooling.
Drives a 20mm rod to seat dowel pins in automotive assemblies, achieving a 79.4 kg vertical lift capacity with a 2:1 safety margin.
When sizing this unit, stepping down to the SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to the SDA80 provides 2513.3 N. The 1558.6 N output at 0.5 MPa translates to a safe working load of roughly 935 N (about 60% capacity) or a vertical lift of approximately 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63mm bore, 5mm stroke, PT1/4 port, female M10x1.5 rod thread, FKM seals, and no magnet.
A plain compact cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near the stroke end rather than locking the piston. If your application must hold a load without live pressure, integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
Quick checklist
At 0.5 MPa, the push force is 1558.6 N and the pull force is 1401.5 N. At 0.7 MPa, push is 2182.1 N and pull is 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a proof pressure of 1.5 MPa and a speed range of 30-500 mm/s.
No, this specific SKU lacks the S option, meaning it has no piston magnet and cannot trigger AirTAC reed or electronic switches. You must select the SDA63X5HS variant to enable sensing via the body grooves. Additionally, it uses fixed NBR bumpers for end deceleration, not an adjustable air cushion.
