The AirTAC AirTAC SDA63X5B Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 5mm 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 SDA63X5B is a double-acting, single-rod compact cylinder engineered to deliver 1558.6 N of push force at 0.5 MPa. Its short, riveted body assembly minimizes axial mounting depth, saving valuable machine footprint space where a traditional round-body unit would be too long. The unit operates at speeds between 30-500 mm/s and features a hard-anodized bore for extended service life.
This specific SKU includes a male M18x1.5 piston rod thread for robust load coupling and utilizes a PT1/4 air port. It relies on a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion. Because this model lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches.

Drives the short 5 mm stroke to rapidly fold heavy cardboard flaps on high-speed packaging lines, utilizing the 1558.6 N push force to overcome material stiffness.
Seats dowel pins into metal assemblies on an automated machining cell, leveraging the male M18x1.5 rod end for a secure tooling connection and minimal axial depth.
Briefly pushes thick steel brackets into exact position for robotic welding, taking advantage of the compact riveted body to fit within tight fixture clearances.
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, allowing you to scale your drive force precisely. Based on the 1558.6 N output at 0.5 MPa, a safe working load is approximately 935 N (60% capacity), translating to a vertical lift capability of about 79.4 kg with a 2:1 safety margin. To order, confirm the 63 mm bore, 5 mm stroke, PT1/4 port, and the male M18x1.5 rod thread. Note that a standard compact cylinder drifts when air pressure is lost or a valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock, so add an external rod lock or pilot-operated check valve if the application requires position holding.
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, the push is 2182.1 N and the pull is 1962.2 N. The theoretical maximum push is 318 kgf at the 1.0 MPa operating pressure limit.
It uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits, which is not an adjustable air cushion. It does not hold a load if air pressure drops; the piston will drift, so an external rod lock or pilot-operated check valve is required for position holding.
