The AirTAC AirTAC SDA80X25B Compact Cylinder | 80mm Bore is a genuine double-acting COMPACT (thin) air cylinder with a Ø80mm bore and 25mm 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 SDA80X25B is a double-acting single-rod compact cylinder engineered for high-force actuation within a minimal axial footprint. It delivers a substantial 2513.3 N push force at 0.5 MPa (3518.6 N at 0.7 MPa), achieved through an 80 mm bore and a robust 25 mm piston rod. The riveted body design drastically reduces overall mounting length compared to conventional round-body units, making it ideal for heavy-duty machinery where space is strictly limited.
This specific SKU features a male M22x1.5 threaded rod end for secure mechanical coupling to your load. Instead of an adjustable air cushion, the internal stroke ends are arrested by a fixed NBR bumper. Note that this configuration ships without a piston magnet, meaning it cannot host AirTAC reed or electronic switches directly unless upgraded to an -S variant.

Uses the 2513.3 N push force to knock heavy stamped metal panels out of a die, where the short 25 mm stroke and compact riveted body fit neatly within the press sub-plate.
Provides the rigid opposing force needed to hold thick steel sheets against a press brake backgauge, leveraging the 25 mm rod to resist deflection during forming.
Acts as a heavy-duty mechanical stopper in automated palletizing cells, halting inbound pallets at 25 mm extension before the lifting fork engages the load.
Selecting this 80 mm bore provides a massive theoretical maximum output of 513 kgf at 1.0 MPa. If your application requires less force, stepping down to the SDA63 yields 1558.6 N at 0.5 MPa, while moving up to the SDA100 provides 3927 N at 0.5 MPa for even heavier demands. A computed safe working load is roughly 1508 N (about 60% of the 0.5 MPa push figure), allowing a vertical lift of approximately 128.1 kg with a 2:1 safety margin.
When ordering, confirm the 80 mm bore, 25 mm stroke, PT3/8 port, and the male M22x1.5 rod thread (-B). Crucially, a standard SDA cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered—the fixed NBR bumper only decelerates the stroke end and acts as neither a lock nor a brake. To suspend loads safely without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
At 0.5 MPa, this 80 mm bore 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. The theoretical maximum push is 513 kgf at the 1.0 MPa operating pressure limit.
No, this specific SKU lacks the internal piston magnet, so it cannot trigger AirTAC reed or electronic switches. You would need to specify the -S option code to enable sensor groove functionality. Additionally, end-stop deceleration relies on a fixed NBR bumper, not an adjustable cushion.
