The AirTAC AirTAC SDA80X15H Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 15mm 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 SDA80X15H is a double-acting, single-rod compact cylinder engineered for high-force tasks in tight axial spaces. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, utilizing a 25mm piston rod and PT3/8 air port. This specific SKU includes an H-designation fluororubber (FKM) seal, providing enhanced resistance to higher temperatures and oil exposure compared to standard NBR.
Its short, riveted body design significantly reduces mounting depth where a traditional round-body cylinder would not fit. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers should be added for high-energy loads. Note that this configuration lacks a piston magnet, so it cannot support magnetic sensing without upgrading to the -S variant.

Provides robust 2513.3 N push force for ejecting dense plastic parts from injection molding platens, where the short 15mm stroke and FKM seals withstand ambient heat.
Acts as a compact press ram in tight sheet metal fabrication cells, delivering precise 15mm clamping action to hold heavy gauge steel during bending operations.
Functions as a high-impact stopper gate in automated palletizing lines, using its 128.1 kg safe vertical lift capacity to arrest heavy product flow within minimal axial footprint.
When sizing this unit, consider stepping down to the SDA63, which offers 1558.6 N of push at 0.5 MPa, or stepping up to the SDA100, which provides 3927 N at the same pressure. For this 80mm bore, the safe working load is approximately 1508 N (about 60% of its 0.5 MPa rating), allowing a vertical lift of roughly 128.1 kg with a 2:1 safety margin. To finalize your order, confirm the 15mm stroke, PT3/8 port, female M14x1.5 rod thread, FKM seal option, and the absence of a sensor magnet.
Keep in mind that a standard double-acting cylinder like this will not hold a load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end rather than locking the rod. For suspended or vertical loads that must be held without live pressure, you must integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
Quick checklist
This 80mm bore double-acting cylinder delivers 2513.3 N push and 2267.8 N pull at 0.5 MPa, and 3518.6 N push at 0.7 MPa. The theoretical maximum push force is 513 kgf at 1.0 MPa. It operates between 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds from 30-500 mm/s.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need to select the -S variant to enable sensing. Additionally, it relies on a fixed NBR bumper for end-of-stroke deceleration, not an adjustable air cushion.
