The AirTAC AirTAC SDA63X30SG 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 SDA63X30SG is a double-acting, single-rod compact cylinder engineered to deliver a substantial 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into an ultra-short unit, drastically reducing axial mounting depth compared to conventional round-body designs. The 63 mm bore features a hard-anodized inner wall and a two-way piston seal for reliable operation.
This specific configuration includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also utilizes a G (BSPP) port thread option on the PT1/4 air supply ports. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be specified for high-energy cycling.

Secures machining pallets inside automated workholding zones where the 1558.6 N extend force locks heavy fixtures without consuming valuable Z-axis envelope.
Actuates high-speed sorting flaps on beverage packaging lines, utilizing the 30 mm stroke and built-in magnet to trigger electronic position switches.
Ejects formed sheet metal parts from shallow press dies, relying on the fixed NBR bumper to absorb impact energy during rapid 30 mm ejection cycles.
When sizing this actuator, consider stepping down to the SDA50, which provides 981.7 N of push force at 0.5 MPa, or moving up to the SDA80 for 2513.3 N at the same pressure. For the SDA63X30SG, a safe working load is approximately 935 N (about 60% of the 0.5 MPa push figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. To finalize your order, confirm the 63 mm bore, 30 mm stroke, G port thread, female rod-end thread (M10x1.5), and the required magnetic sensor option.
Keep in mind that a standard compact cylinder cannot hold a load if air pressure drops or the directional valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near its end limits and does not function as a mechanical lock. If your application requires static holding, you must integrate an external rod lock or a pilot-operated check valve into the pneumatic circuit.
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 the 1.0 MPa operating pressure limit.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion, so external shock absorbers may be needed for high-speed loads. The included -S magnet allows you to track position using AirTAC reed or electronic switches mounted in the body grooves.
