The AirTAC AirTAC SDA63X90H Compact Cylinder | 63mm Bore FKM is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 90mm 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 SDA63X90H is a double-acting single-rod compact cylinder engineered for rigorous pneumatic tasks. It generates 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa, utilizing a 63 mm bore and a 90 mm stroke. This specific SKU features an H-designation fluororubber (FKM) seal for enhanced thermal and oil resistance, operating within a standard temperature range of -20 to +70 C.
Designed with a short riveted body, this unit significantly reduces axial mounting depth compared to round-body alternatives, saving valuable machine footprint. The hard-anodized bore houses a two-way piston seal, while a fixed NBR bumper at each end absorbs end-stop impact. Because this configuration lacks the -S option, it has no piston magnet and cannot support magnetic switches. The 20 mm rod uses an M10x1.5 female thread, and air connections use a PT1/4 port.

Provides robust 1558.6 N extension force to eject dense plastic components from injection molding tools, where the FKM seal withstands ambient heat radiating from the mold plates.
Drives a 90 mm stroke to fold corrugated cardboard flaps on heavy-duty palletizing lines, utilizing the compact riveted body to fit within tight conveyor side-frame clearances.
Pushes sheet metal blanks into precise alignment dies before stamping, taking advantage of the 20 mm rod diameter to resist deflection during heavy industrial positioning.
When sizing this actuator, evaluate your force requirements carefully. If the 1558.6 N push at 0.5 MPa is excessive, stepping down to the SDA50 yields 981.7 N. Conversely, if your payload demands greater thrust, the SDA80 provides 2513.3 N. Based on the 0.5 MPa rating, the safe working load is roughly 935 N (about 60% of capacity), translating to a vertical lift capability of approximately 79.4 kg with a 2:1 safety margin.
Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the stroke end and does not function as a locking brake. To suspend a load safely without live pressure, you must integrate an external rod lock or a pilot-operated check valve. To order, confirm the 63 mm bore, 90 mm stroke, PT1/4 port, FKM seal, and female rod thread.
Quick checklist
This double-acting 63 mm bore cylinder delivers a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push is 318 kgf at 1.0 MPa. Operating pressure spans 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and the operational speed range is 30-500 mm/s.
No, the piston will drift downward if air is lost or the valve is centered; the fixed NBR bumper only decelerates the rod near the stroke end and acts neither as a lock nor an adjustable air cushion. To maintain a vertical position without live pressure, an external rod lock or pilot-operated check valve is required. For high-speed cycles, consider adding an external shock absorber to manage impact energy.
