About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X240-10
The AirTAC SAIJ80X240-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 240 mm nominal stroke that can be fine-tuned backward by up to 10 mm, providing a usable travel window of 230 to 240 mm for precise end-position calibration. Delivering 2513 N of pull force at 0.5 MPa, it handles robust actuation tasks while maintaining a standard ISO 15552 mounting footprint.
This model incorporates a carbon steel piston rod with an M20x1.5 thread, offering high tensile strength and excellent resistance to side loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It uses a PT tapered port thread and includes adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X240-10 Is Used
Machine Changeover
Dial in the 230-240 mm retract stop during product size changes without swapping the cylinder or repositioning external physical stops.
Diversion Gate Tuning
Precisely set the actuation endpoint on sorting gates to accommodate varying package dimensions on the fly.
End-Position Calibration
Compensate for mechanical wear or minor fixture misalignment by adjusting the rear stopper by up to 10 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X240-10 the Right Cylinder?
Choose this 80 mm bore when you need 2513 N of pull force at 0.5 MPa, stepping up from a 63 mm bore that provides 1402 N. The 10 mm rear adjustment screw is ideal for fine-tuning the retract end at commissioning or during product changeover without adding external stops. When replacing an ISO 15552 cylinder, match the 80 mm bore, 240 mm stroke, 10 mm adjustment, PT G3/8 port, and standard carbon steel rod. For strokes of 300 mm or more, an external guide is recommended to prevent rod deflection.
Note that the rear adjuster acts as a travel stop, not a lock. The SAIJ80X240-10 will not hold a load without live air pressure. For true load-holding requirements, consider the SAIL pneumatic lock or BSAI clamp-lock series instead.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80X240-10 FAQ
It features a rear stopper screw that allows you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 230 to 240 mm, letting you fine-tune the end position at commissioning without replacing the cylinder.
At an operating pressure of 0.5 MPa, the SAIJ80X240-10 generates 2513 N of pull force and 3518 N of push force. It operates at speeds between 30 and 800 mm/s.
