The AirTAC AirTAC SDA63X140SH 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 SDA63X140SH is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. Because the 140 mm stroke exceeds the 130 mm standard limit for this 63 mm bore, this specific configuration is manufactured as a non-standard, made-to-order unit. The riveted body design significantly reduces axial mounting depth compared to conventional round-body cylinders, saving valuable machine footprint.
This model includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic switches along the body grooves. It also features a male M18x1.5 threaded piston rod (-B) for secure load coupling, and utilizes a fluororubber (FKM) seal (-H) for enhanced thermal and oil resistance. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.

Drives the ejection plate in plastic injection molding machines where the 1558.6 N extend force breaks parts free, while the FKM seals withstand high ambient shop heat.
Lifts layered product stacks within packaging lines, utilizing the 79.4 kg vertical lift capacity to raise goods efficiently within a tight axial frame envelope.
Actuates routing gates on CNC woodworking conveyors, where the male M18x1.5 rod end secures heavy brackets and the 140 mm stroke clears large panel profiles.
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 for a substantial 2513.3 N push at 0.5 MPa. For this 63 mm bore, the safe working load calculates to approximately 935 N (about 60% of the 0.5 MPa 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, 140 mm non-standard stroke, PT1/4 port, male M18x1.5 rod thread, FKM seals, and the required sensor magnet.
Keep in mind that a standard compact actuator cannot hold a load if air pressure drops or the valve is centered; the piston will drift. The fixed NBR bumper only decelerates the stroke near its end and does not act as a locking brake. If your application demands position holding without live pressure, you must 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, increasing to 2182.1 N push and 1962.2 N pull at 0.7 MPa. The theoretical maximum push force is 318 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a speed range of 30-500 mm/s.
It relies on a fixed NBR bumper at each end to decelerate the piston, which is not an adjustable air cushion. For high-speed or high-energy cycles, you should add an external shock absorber. Additionally, it does not hold position naturally; if air is lost, the piston drifts, requiring an external rod lock or pilot-operated check valve for secure load holding.
