The AirTAC AirTAC SDA63X30H Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 30mm 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 SDA63X30H is a double-acting, single-rod compact cylinder engineered with a 63 mm bore and 30 mm stroke. A short riveted assembly joins the barrel, rear cover, piston, and rod, drastically reducing axial mounting depth compared to round-body alternatives. Delivering 1558.6 N of push force at 0.5 MPa, this unit features a hard-anodized bore and a two-way piston seal for reliable pneumatic operation.
This specific SKU includes an H designation, meaning it utilizes fluororubber (FKM) seals for enhanced resistance to higher temperatures and oily environments. The 20 mm piston rod exits via a female M10x1.5 thread, and air connects through PT1/4 ports. End-stopping relies on a fixed NBR bumper rather than an adjustable air cushion, so external shock absorbers should be specified for high-energy cycles.

Mounts directly onto injection molding platens to eject hot plastic parts, where the FKM seals withstand ambient radiated heat and the short body conserves machine footprint.
Actuates routing gates on printed circuit board assembly lines, using the 1558.6 N extend force to positively shift heavy aluminum pallets at 30 mm of travel.
Raises corrugated carton blanks into sealing position, safely handling the 79.4 kg vertical lift capacity while the fixed NBR bumper arrests the end of motion.
When sizing this actuator, consider stepping down to the SDA50, which provides 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which yields 2513.3 N at the same pressure. For the SDA63X30H, a safe working load is approximately 935 N (about 60 percent of the 1558.6 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 30 mm stroke, PT1/4 port, female rod thread, and FKM seals. Note that this configuration lacks a piston magnet, so position sensing is not possible without the -S option. Furthermore, a standard compact 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. If your application requires absolute load holding, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 63 mm bore double-acting cylinder generates 1558.6 N push and 1401.5 N pull at 0.5 MPa. At 0.7 MPa, push increases to 2182.1 N and pull to 1962.2 N. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and travels at speeds of 30-500 mm/s.
No, this specific SKU does not have a piston magnet, so it cannot trigger AirTAC reed or electronic switches. To add sensing capabilities, you must select the -S option code. Additionally, this model uses fixed NBR bumpers to decelerate the piston at the ends, which cannot be field-adjusted like an air cushion.
