The AirTAC AirTAC SDA80X150B 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 SDA80X150B is a double-acting single-rod compact cylinder engineered to deliver a robust 2513.3 N push force at 0.5 MPa. Utilizing a short riveted body design, it significantly reduces axial mounting depth compared to conventional round-body units, saving valuable machine footprint in tight assemblies. This specific SKU includes a male M22x1.5 piston rod thread for secure mechanical coupling to your load.
Because the 150 mm stroke exceeds the 130 mm standard maximum for this 80 mm bore, this unit is provided as a non-standard, made-to-order configuration. It relies on a fixed NBR bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Note that this particular model lacks a piston magnet and therefore cannot support magnetic sensing.

Drives the ejection plate in plastic injection molding machines where the male M22x1.5 rod secures the knock-out plate and the compact body minimizes rear clearance.
Positions heavy sheet metal blanks at stamping presses, utilizing the 2513.3 N push force to align parts before the main hydraulic ram descends.
Actuates raising and lowering safety gates on automated pallet conveyors, providing reliable vertical movement within a restricted frame envelope.
When sizing this actuator, consider stepping down to the SDA63, which provides 1558.6 N of push force at 0.5 MPa, or moving 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 this cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the stroke end. For load holding, an external rod lock or pilot-operated check valve is required. To order, confirm the 80 mm bore, 150 mm non-standard stroke, PT3/8 port, male M22x1.5 rod thread, and no magnet.
Quick checklist
This 80 mm bore double-acting cylinder generates 2513.3 N push and 2267.8 N pull at 0.5 MPa. At 0.7 MPa, push increases to 3518.6 N. The theoretical maximum force is 513 kgf at the 1.0 MPa operating pressure limit.
No, this unit uses a fixed NBR bumper to decelerate at stroke ends, not a field-adjustable air cushion. Additionally, because it lacks the -S magnet option, it cannot accept reed or electronic switches; you would need the -S variant for position sensing.
