The AirTAC AirTAC SDA80X30B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 30mm 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 SDA80X30B is a double-acting, single-rod compact cylinder engineered to deliver a substantial 2513.3 N push force at 0.5 MPa. Its riveted assembly merges the barrel, rear cover, piston, and rod into a highly shortened unit, drastically reducing axial mounting depth where a conventional round-body actuator would fail to fit. This space-saving footprint makes it highly effective for tight machine layouts.
This specific SKU includes a male M22x1.5 threaded piston rod end for robust mechanical coupling to your load. The bore is hard-anodized for durability, and the design relies on a fixed NBR bumper at each end to absorb end-stop impact. Because this configuration lacks the -S magnet option, it cannot support magnetic position sensing without changing the model code.

Drives the ejection plate inside a tight injection molding machine bay, utilizing the short riveted body to fit within constrained mold depths while providing 2513.3 N of extension force.
Ejects thick-gauge stamped metal parts from a hydraulic press bed, where the male M22x1.5 rod end securely threads into the ejector tooling to handle high extraction loads.
Raises and lowers a heavy palletizing fork mechanism, safely lifting up to 128.1 kg vertically thanks to a 2:1 safety margin on the 0.5 MPa operating pressure.
When sizing this actuator, evaluate your force requirements carefully. If you need less push, stepping down to the SDA63 provides 1558.6 N at 0.5 MPa; if you require more power, the SDA100 offers 3927 N at 0.5 MPa. For the SDA80X30B, the safe working load is approximately 1508 N (about 60% of the 2513.3 N figure at 0.5 MPa), translating to a vertical lift capacity of roughly 128.1 kg with a 2:1 safety margin. Ensure you specify the 80 mm bore, 30 mm stroke, PT3/8 port, and the male M22x1.5 rod thread when ordering.
Keep in mind that a standard compact cylinder does not hold its position if air pressure is lost or the valve is centered. The piston will drift, and the fixed NBR bumper only decelerates the stroke near the end limits rather than acting as a lock. If your application must maintain a load without live pressure, you must integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this double-acting cylinder provides 2513.3 N of push force and 2267.8 N of pull force. At 0.7 MPa, push increases to 3518.6 N and pull to 3175 N. The theoretical maximum push is 513 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
No, it uses a fixed NBR bumper at each end to decelerate the stroke, which is not an adjustable air cushion or a braking lock. Additionally, this specific SKU lacks a piston magnet, so it cannot support magnetic switches; you would need the -S variant to use reed or electronic sensors.
