The AirTAC AirTAC SDA63X150S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 150mm 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 SDA63X150S is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would be too bulky. A 150 mm stroke on this 63 mm bore requires a made-to-order configuration, extending beyond the 130 mm standard limit.
This specific model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. Deceleration at the stroke extremes relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber to prevent impact damage.

Acts as a secondary ejector on a plastics injection molding press, using the 150 mm made-to-order stroke to clear deep mold cavities where standard lengths fall short.
When sizing this actuator, stepping down to an SDA50 yields 981.7 N of push at 0.5 MPa, while stepping up to an SDA80 provides 2513.3 N. Based on the 1558.6 N output at 0.5 MPa, a safe working load is approximately 935 N (around 60 percent capacity), translating to a vertical lift capability of roughly 79.4 kg with a 2:1 safety margin. Because this is a double-acting design, air pressure is required to maintain position; if air is lost, the piston will drift. To hold a load securely without live pressure, an external rod lock or pilot-operated check valve must be fitted. Ensure your order specifies the PT1/4 port, the 150 mm non-standard stroke, the female M10x1.5 rod thread, and the required magnetic sensor option.
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 force is 2182.1 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.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion or a braking lock. For high-speed applications, an external shock absorber is recommended. Additionally, the cylinder will drift if air pressure is lost, so an external rod lock or pilot-operated check valve is required to hold a load safely.
