The AirTAC AirTAC SDA80X85H 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 SDA80X85H is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted body assembly significantly reduces overall mounting depth compared to conventional round-body units, making it ideal for tight machine layouts. Operating at 0.15-1.0 MPa, it generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa.
This specific SKU features an 80 mm bore, an 85 mm stroke, and a robust 25 mm piston rod. Equipped with high-temperature fluororubber (FKM) seals, it is built to withstand demanding environments. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing.

Drives heavy ejector pins in plastic injection molding machinery where the compact riveted body minimizes rearward space requirements and FKM seals resist thermal degradation.
Actuates heavy-duty stock guides and clamps in automated press lines, utilizing the 2513.3 N push force to secure steel blanks prior to the stamping stroke.
Raises and lowers loaded pallets in packaging conveyors, providing the necessary 128.1 kg vertical lift capacity while fitting into narrow vertical lift columns.
When sizing this actuator, evaluate your force requirements carefully. Stepping down, the SDA63 provides 1558.6 N of push at 0.5 MPa; stepping up, the SDA100 yields 3927 N at the same pressure. For the SDA80X85H, the safe working load is approximately 1508 N (about 60% of the 2513.3 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 85 mm stroke, PT3/8 port, female M14x1.5 rod thread, and FKM seals. If the application must hold a load without live pressure, note that the piston will drift on air loss—the fixed bumper only decelerates near the stroke end and acts as neither a lock nor a brake. An external rod lock or pilot-operated check valve is required for secure holding.
Quick checklist
This double-acting cylinder generates 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 within a pressure range of 0.15-1.0 MPa, handles speeds of 30-500 mm/s, and functions in temperatures from -20 to +70 C.
No, this specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. To add sensing capabilities, you would need the -S variant. Additionally, end-stop deceleration is handled by a fixed NBR bumper, which is not field-adjustable; for high-energy cycles, consider slowing the approach or adding an external shock absorber.
