The AirTAC AirTAC SDA63X35H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 35mm 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 SDA63X35H is a double-acting single-rod compact cylinder engineered for tight axial footprints. Its riveted assembly keeps overall length minimal where a conventional round-body unit would not fit. Delivering 1558.6 N of push force at 0.5 MPa, this 63 mm bore model features a 20 mm piston rod and a PT1/4 port. The H designation indicates a fluororubber (FKM) seal for heightened thermal and oil resistance.
This unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this SKU lacks the S option, it has no piston magnet and cannot host reed or electronic switches. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

Ejecting dense plastic parts from injection moulding tools where the 1558.6 N extend force reliably clears the cavity without requiring excessive axial machine depth.
Folding heavy corrugated carton flaps on a continuous packaging line, utilizing the 35 mm stroke and FKM seals to withstand elevated ambient temperatures.
Actuating a heavy-duty diverter gate on a pallet handling conveyor, where the 20 mm rod withstands lateral impact forces during heavy payload routing.
When sizing this actuator, 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. For this 63 mm bore, a safe working load is approximately 935 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of about 79.4 kg with a 2:1 safety margin. To order, confirm the 35 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the FKM seal. Note that a plain compact cylinder drifts if air pressure drops; use an external rod lock or pilot-operated check valve if the load must be held.
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, which is the maximum operating pressure.
No, this specific SKU lacks the S option, meaning it has no piston magnet and cannot trigger reed or electronic switches. You would need the SDA63X35HS variant for sensing capabilities.
