The AirTAC AirTAC SDA80X50SBH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 50mm 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 SDA80X50SBH is a double-acting single-rod compact cylinder engineered for heavy-duty automation within a minimal axial footprint. Its riveted 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 configuration includes a built-in piston magnet for position sensing, a male M22x1.5 piston rod end, and high-temperature fluororubber (FKM) seals for enhanced durability.
The 80 mm bore operates on PT3/8 ports and relies on a fixed NBR bumper at each stroke end to absorb impact energy. This bumper decelerates the load near the end of travel but is not an adjustable air cushion; for high-speed cycling, adding an external shock absorber is advisable. The integrated magnet supports AirTAC reed or electronic switches fitted into the body grooves, while the hard-anodized inner wall ensures long seal life.

Drives heavy plastic part ejection plates where the short riveted body minimizes machine intrusion and the FKM seals withstand residual heat.
Lifts loaded pallets vertically, utilizing the 2513.3 N push force to raise roughly 128 kg safely with a 2:1 dynamic margin.
Secures heavy stamping dies using the male M22x1.5 rod end for rigid mechanical coupling during high-force press operations.
Selecting this 80 mm bore model provides a theoretical maximum push of 513 kgf at 1.0 MPa. When sizing your system, stepping down to the SDA63 yields 1558.6 N of push force at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N at the same pressure. Based on the 2513.3 N output at 0.5 MPa, the computed safe working load is approximately 1508 N (60% capacity), which translates to a vertical lift capability of about 128.1 kg with a 2:1 safety margin.
Keep in mind that a standard compact cylinder will drift and cannot hold a load if air pressure drops or the valve is centered—the fixed rubber bumper only decelerates the stroke end and acts as neither a lock nor a brake. To maintain vertical position holding without live pressure, an external rod lock or pilot-operated check valve is required. Confirm your ordering essentials: 80 mm bore, 50 mm stroke, PT3/8 port, S magnet, B male-thread rod, and H FKM seals.
Quick checklist
This 80 mm bore double-acting cylinder uses a PT3/8 air port. It 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 force is 513 kgf at 1.0 MPa.
It uses a fixed NBR bumper at each end to decelerate the piston, which is not a field-adjustable air cushion. The cylinder cannot hold a vertical load if air is lost; the piston will drift. For position holding, you must install an external rod lock or a pilot-operated check valve.
