The AirTAC AirTAC SDA80X85S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 85mm 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 SDA80X85S is a double-acting single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, and piston into a highly unified unit, drastically reducing axial mounting depth compared to conventional round-body designs. This space-saving footprint is critical when integrating heavy actuators into tight machine frames.
Equipped with a built-in piston magnet (-S), this unit operates seamlessly with AirTAC reed or electronic switches via the body grooves. The 25 mm piston rod utilizes a female M14x1.5 thread, while the PT3/8 port manages airflow. End-stopping relies on a fixed NBR bumper rather than an adjustable cushion, ensuring reliable deceleration across its 85 mm travel.

Provides the heavy 2513.3 N push required to eject dense plastic parts from injection molding dies where axial frame depth is severely restricted.
Drives vertical lifting platforms in end-of-line packaging, moving loads up to 128.1 kg safely while benefiting from the compact riveted body footprint.
Shifts heavy stamping blanks between press stations, utilizing the 25 mm rod and fixed NBR bumpers to absorb kinetic energy during rapid 85 mm strokes.
When sizing this 80 mm bore actuator, consider stepping down to the SDA63 which yields 1558.6 N push at 0.5 MPa, or scaling up to the SDA100 which provides 3927 N. The SDA80X85S offers a safe working load around 1508 N (approximately 60% of its 2513.3 N capacity) and can vertically lift roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 80 mm bore, 85 mm stroke, PT3/8 port, built-in magnet, and female rod-end thread.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure drops or the directional valve centers; the piston will drift. If your application requires position holding without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push at 0.7 MPa. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, handles temperatures from -20 to +70 C, and runs at speeds of 30-500 mm/s.
No, the SDA80X85S uses 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 or slow down the approach speed to prevent damage.
