The AirTAC AirTAC SDA63X80S Compact Cylinder | 63mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø63mm bore and 80mm 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 SDA63X80S is a double-acting, single-rod compact cylinder engineered to deliver a robust 1558.6 N push force at 0.5 MPa. By utilizing a short riveted body assembly, it significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight spaces. This 63 mm bore unit features a 20 mm piston rod and PT1/4 air ports.
Because this configuration includes the S option, it possesses a built-in piston magnet designed for direct mounting of AirTAC reed or electronic switches along the body grooves. End-stop deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning operators should slow the approach or utilize external shock absorbers for high-energy loads. Operating speed ranges from 30-500 mm/s.

Provides the 1558.6 N extension force needed to eject dense plastic parts from injection molding tools, fitting neatly into shallow mold platens.
Pushes heavy cartons across high-speed logistics conveyor lines, utilizing the 80 mm stroke and magnetic switches for precise divert confirmation.
Secures heavy steel workpieces in light press operations, offering reliable holding power within a compact machinery footprint.
When sizing this unit, evaluate your force requirements carefully. 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. For this specific 63 mm bore, the computed safe working load is approximately 935 N (60% of the 0.5 MPa figure), translating to a vertical lift capacity of roughly 79.4 kg with a 2:1 safety margin. Confirm your ordering essentials: 63 mm bore, 80 mm stroke, PT1/4 port, female M10x1.5 rod thread, and the required magnetic sensor option.
Note that a standard compact actuator cannot maintain its position upon air loss or valve centering. The piston will drift, and the fixed NBR bumper only decelerates the stroke near its end without acting as a lock. If your application demands strict position holding, integrate an external rod lock or a pilot-operated check valve.
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 and the pull force is 1962.2 N. The theoretical maximum push force is 318 kgf at the maximum operating pressure of 1.0 MPa.
No, it uses a fixed NBR bumper at each end to decelerate the piston near the stroke limits. It is not an adjustable air cushion, so for high-speed or high-energy cycles, you should add an external shock absorber or reduce the approach speed.
