The AirTAC AirTAC SDA80X55BH Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 55mm 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 SDA80X55BH 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. This specific SKU includes a male M22x1.5 piston rod end for secure mechanical load coupling and utilizes fluororubber (FKM) seals for enhanced thermal and oil resistance.
Deceleration at the stroke extremes is handled by a fixed NBR bumper at each end, which absorbs impact energy but is not a field-adjustable air cushion. Operating at speeds of 30-500 mm/s, this 80 mm bore unit features a PT3/8 port and a 25 mm rod. Note that this configuration lacks a piston magnet, so it cannot support position sensing without switching to the -S variant.

Drives heavy ejector pins on a plastic injection molding platen where the 2513.3 N extend force clears dense parts and the short riveted body fits within tight mold voids.
Lifts heavy coil steel strips into a stamping press feeder, utilizing the 128.1 kg vertical lift capacity while the male M22x1.5 rod threads directly into the lifting jaw.
Stages large corrugated shipping cases onto a palletizer conveyor, relying on the FKM seals to withstand elevated ambient temperatures near shrink-wrap tunnels.
When sizing this actuator, evaluate your force requirements carefully. Stepping down to the SDA63 yields 1558.6 N of push at 0.5 MPa, whereas stepping up to the SDA100 provides 3927 N. The SDA80X55BH provides a safe working load of roughly 1508 N (about 60% of its 0.5 MPa capacity) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Confirm your ordering essentials: 80 mm bore, 55 mm stroke, PT3/8 port, male M22x1.5 rod thread, FKM seals, and no sensor magnet.
Be aware that a standard double-acting cylinder does not hold its position if air pressure drops or the directional valve is centered. The piston will drift, and the fixed bumper only decelerates the rod near the stroke end rather than locking it. If your application must maintain a suspended load without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N of push and 2267.8 N of pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum push force is 513 kgf at the 1.0 MPa operating pressure limit.
No adjustable air cushion exists; the cylinder relies on a fixed NBR bumper to decelerate the stroke end. Additionally, this specific SKU lacks a piston magnet, meaning it cannot support reed or electronic switches. You would need the -S variant for position sensing.
