The AirTAC AirTAC SDA80X150S Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 150mm 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 SDA80X150S is a double-acting, single-rod compact cylinder engineered to deliver substantial thrust in a minimal axial footprint. It generates 2513.3 N of push force and 2267.8 N of pull force at 0.5 MPa, utilizing a robust 25 mm piston rod and PT3/8 air ports. Because the 150 mm stroke exceeds the 130 mm standard maximum for this 80 mm bore, this specific configuration is manufactured as a non-standard, made-to-order unit.
The riveted body design integrates the barrel, rear cover, piston, and rod to drastically reduce overall mounting depth compared to conventional round-body units. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning high-energy cycles may require an external shock absorber. Equipped with a built-in piston magnet (-S), the body grooves readily accept AirTAC reed or electronic switches for precise position sensing.

Drives heavy mold ejector plates in plastic injection machinery where the short riveted body saves valuable axial mounting depth within the press platen.
Clears large stamped metal parts from hydraulic presses, utilizing the 2513.3 N push force to reliably knock out dense components at cycle completion.
Raises and lowers heavy tooling fixtures on automated pallet lines, achieving a safe vertical lift of approximately 128.1 kg with a 2:1 safety margin.
When sizing this unit, consider stepping down to the SDA63 bore, which provides 1558.6 N of push at 0.5 MPa, or stepping up to the SDA100, which yields 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 (about 60% capacity), translating to a vertical lift capability of roughly 128.1 kg with a 2:1 safety margin. Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates the piston near stroke end and does not function as a locking brake. If your application requires absolute load holding, integrate an external rod lock or a pilot-operated check valve. To finalize this model, confirm the 80 mm bore, 150 mm non-standard stroke, PT3/8 port, female M14x1.5 rod thread, and the required -S magnet for switch readiness.
Quick checklist
This 80 mm bore double-acting cylinder provides 2513.3 N push and 2267.8 N pull at 0.5 MPa, increasing to 3518.6 N push and 3175 N pull 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, tolerates temperatures from -20 to +70 C, and cycles at speeds between 30-500 mm/s.
No, the piston will drift if air is lost or the directional valve is centered. The fixed NBR bumpers only decelerate the rod near the stroke endpoints and do not act as a mechanical brake. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
