The AirTAC AirTAC SDA80X120BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 120mm 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 SDA80X120BH 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, yielding a robust 2513.3 N push force at 0.5 MPa. This specific SKU includes a male M22x1.5 piston rod end for secure mechanical coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Designed with a 25 mm piston rod and PT3/8 ports, this 80 mm bore model operates at speeds between 30-500 mm/s. End-of-stroke deceleration is handled by a fixed NBR bumper at each end rather than an adjustable air cushion. Because this configuration lacks the -S magnet option, it cannot directly host AirTAC reed or electronic switches; position sensing would require external methods or the -S variant.

Utilizes the 2513.3 N extend force to shift heavy stamping dies into alignment on production lines, taking advantage of the short riveted body to fit within tight machinery envelopes.
Employs the 120 mm stroke and male M22x1.5 rod to fold corrugated box flaps securely before strapping, relying on FKM seals to withstand elevated ambient temperatures near heat tunnels.
Applies concentrated push force to flatten thick steel plates, where the fixed NBR bumper effectively absorbs the sudden impact energy at the end of the stroke.
When sizing this model, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or stepping up to the SDA100, which delivers 3927 N at the same pressure. For the SDA80X120BH, the computed safe working load is approximately 1508 N (about 60% of its 2513.3 N capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. Ensure your ordering essentials specify the 80 mm bore, 120 mm stroke, PT3/8 port, male M22x1.5 rod thread, and FKM seal option.
Note that a plain compact cylinder does not hold its position or load when air pressure is lost or the directional valve is centered; the piston will drift, and the fixed NBR bumper only decelerates the stroke near the end without acting as a lock. If your application requires a held load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting cylinder generates a push force of 2513.3 N and a pull force of 2267.8 N at 0.5 MPa. At 0.7 MPa, the push increases to 3518.6 N. The theoretical maximum push is 513 kgf at 1.0 MPa. It operates within a pressure range of 0.15-1.0 MPa, with a proof pressure of 1.5 MPa, and a temperature range of -20 to +70 C.
No, this specific SKU does not include the -S piston magnet, so it cannot host AirTAC reed or electronic switches in the body grooves. Additionally, end-stop deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion; for high-speed operations, you should add an external shock absorber or slow the approach speed.
