The AirTAC AirTAC SDA63X80H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 80mm 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 SDA63X80H is a double-acting single-rod compact cylinder featuring a 63 mm bore and an 80 mm stroke. It generates a substantial 1558.6 N of push force and 1401.5 N of pull force at 0.5 MPa. This specific SKU includes an H designation, utilizing a fluororubber (FKM) seal for enhanced resistance to higher temperatures and oily environments while operating within the standard -20 to +70 C range.
Its short riveted body integrates the barrel, rear cover, piston and rod to minimize axial mounting depth, saving valuable machine footprint where a standard round-body unit would not fit. The bore is hard-anodized for longevity, and end-of-travel deceleration is handled strictly by a fixed NBR bumper rather than an adjustable air cushion. This unit lacks a piston magnet, so it cannot support position sensing without upgrading to the -S variant.

Provides robust ejection force for plastic injection moulding machines, where the FKM seals withstand residual heat and the compact depth fits tight ejection stations.
Drives heavy cardboard flap folders on automated packaging lines, utilizing the 1558.6 N extend force to cleanly fold thick corrugated materials before strapping.
Acts as a short-stroke pusher in metal stamping feed systems, advancing heavy coil stock into the press within a constrained machinery footprint.
When sizing this actuator, evaluate your neighbours: 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 at the same pressure. For the SDA63X80H, a safe working load is approximately 935 N (about 60% of the 1558.6 N figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 80 mm stroke, PT1/4 port, female M10x1.5 rod thread, FKM seals, and no magnet. Note that a plain compact cylinder drifts if air pressure is lost or the valve is centred; the fixed bumper only decelerates near stroke end and does not function as a lock or brake. To hold a load securely without live pressure, integrate an external rod lock or a pilot-operated check valve.
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 force 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 does not have a piston magnet and therefore cannot support position sensing. You would need the -S option to add a magnet for AirTAC reed or electronic switches. Additionally, end stops rely on a fixed NBR bumper for deceleration, not an adjustable cushion, so external shock absorbers may be needed for high-energy loads.
