The AirTAC AirTAC SDA63X140S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 140mm 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 SDA63X140S 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, piston, and rod into a highly shortened axial footprint, conserving valuable machine space where traditional round-body units cannot fit. The 140 mm stroke exceeds the 130 mm standard maximum for this 63 mm bore, making it a non-standard, made-to-order configuration.
This unit includes a built-in piston magnet (-S) compatible with AirTAC reed or electronic switches mounted in the body grooves. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy cycles. The 20 mm rod utilizes a female M10x1.5 thread, operating at speeds of 30-500 mm/s.

Drives heavy diverter arms on automated palletizing lines, utilizing the 1558.6 N extend force to shift boxed inventory lanes at high cycling speeds.
Elevates product tiers in continuous wrap machinery, where the 140 mm stroke repositions components and the compact riveted body minimizes vertical headspace.
Actuates secondary ejection pins on plastic molding equipment, using the 20 mm rod to push finished parts clear of the tool cavity safely.
When sizing this actuator, consider stepping down to the SDA50, which yields 981.7 N of push at 0.5 MPa, or moving up to the SDA80, which provides 2513.3 N at the same pressure. Based on the 1558.6 N output, the computed 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. Be aware that a standard SDA body will drift and cannot hold a load if air pressure drops or the valve is centered; maintaining vertical loads requires an external rod lock or pilot-operated check valve. To order, confirm the 63 mm bore, 140 mm non-standard stroke, PT1/4 port, female M10x1.5 rod thread, and the required magnetic sensor option.
Quick checklist
This 63 mm bore double-acting cylinder generates a push force of 1558.6 N and a pull force of 1401.5 N at 0.5 MPa. At 0.7 MPa, the push increases to 2182.1 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, which is not an adjustable air cushion. For high-speed cycles, adding an external shock absorber is advised. Additionally, it cannot hold a load if air is lost; the piston will drift, requiring an external rod lock for position retention.
