The AirTAC AirTAC SDA80X65H Compact Cylinder | 80mm Bore FKM is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 65mm 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 SDA80X65H is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces mounting depth compared to conventional round-body units, delivering a robust 2513.3 N push force at 0.5 MPa alongside a 25 mm piston rod. This specific H variant utilizes a fluororubber (FKM) seal to endure elevated thermal and oil-exposure conditions better than standard NBR.
Deceleration at the stroke extremes relies on a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require external shock absorbers to prevent impact damage. Because this configuration lacks the S magnet option, it cannot support magnetic position sensing. Operating at 30-500 mm/s, the unit safely handles a working load of roughly 1508 N, which translates to a vertical lift capacity of about 128.1 kg with a 2:1 safety margin.

Drives heavy ejector pins in plastic injection molding machinery, utilizing the FKM seal to withstand ambient heat radiating from the mold platens.
Raises and lowers loaded pallets in automated packaging lines, providing the 128.1 kg vertical lift capacity needed for heavy product transfer.
Moves heavy back-gauge fingers on metal forming press brakes where the short 65 mm stroke and high push force accurately locate sheet metal.
When sizing this 80 mm bore actuator, compare its 2513.3 N push at 0.5 MPa against adjacent options: stepping down to the SDA63 yields 1558.6 N, while upgrading to the SDA100 provides 3927 N. To finalize your order, confirm the 65 mm stroke, PT3/8 porting, female M14x1.5 rod-end thread, and the FKM seal specification. If your mechanism must maintain vertical position during a compressed air loss or valve centering, note that this cylinder will drift; the fixed bumper only slows the piston near the end of travel and does not function as a locking brake, so an external rod lock or pilot-operated check valve is necessary for fail-safe holding.
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 force is 513 kgf at 1.0 MPa, which is the maximum operating pressure.
No, this specific SKU does not include the S piston magnet, so it cannot support reed or electronic switches. You would need the SDA80X65HS variant for position sensing, while this version focuses on the FKM high-temperature seal.
