The AirTAC AirTAC SDA80X100SH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 100mm stroke, PT3/8 air ports and a riveted short body that saves mounting depth. Sensor slots around the body accept magnetic switches for position sensing.
The AirTAC SDA80X100SH is a double-acting, single-rod compact cylinder engineered for heavy-duty pneumatics within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a substantial 2513.3 N push force at 0.5 MPa. Equipped with a fluororubber (FKM) seal, this variant provides enhanced thermal and oil resistance for demanding environments.
This model features a 25 mm piston rod and PT3/8 ports, utilizing a fixed NBR bumper at each end to decelerate the stroke. Because the -S option is specified, a built-in piston magnet enables position detection via an AirTAC reed or electronic switch mounted in the body grooves. The 100 mm stroke operates at speeds between 30 and 500 mm/s.

Provides robust 2513.3 N push force to eject dense plastic components from injection molding machinery, where the FKM seal withstands ambient heat.
Indexes heavy metal forming tools on press brakes, utilizing the 100 mm stroke to set precise bending depths securely.
Raises lower-tier pallets in high-throughput packaging lines, taking advantage of the compact riveted body to fit within tight vertical lift columns.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63, which yields 1558.6 N of push force at 0.5 MPa, or moving up to the SDA100, which provides 3927 N at the same pressure. For this SDA80X100SH configuration, verify your requirements for the 100 mm stroke, PT3/8 porting, female M14x1.5 rod thread, the FKM seal, and the magnetic switch option. A safe working load is approximately 1508 N (about 60% of the 0.5 MPa push force), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. Remember that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and does not function as a lock. To maintain a suspended load, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, the push force is 2513.3 N and the pull force is 2267.8 N. At 0.7 MPa, the push force is 3518.6 N. The theoretical maximum push force is 513 kgf at 1.0 MPa, with an operating pressure range of 0.15-1.0 MPa.
No, it relies on a fixed NBR bumper at each end to absorb end-stop impact. It is not an adjustable air cushion, nor does it act as a braking lock. For high-speed or high-energy cycles, you should add an external shock absorber or slow the approach speed.
