About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10
The AirTAC SAIJ80X140-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 2513N pull force at 0.5MPa, making it well-suited for medium-to-heavy handling tasks.
This model provides a usable travel window of 130-140mm, allowing you to fine-tune the retract end position at commissioning without adding external stops. It uses a PT tapered port thread and includes variable air cushions at both ends to decelerate the load.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10 Is Used
Machine Changeover
Dial in the 130-140mm travel window during product size transitions without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract stroke by up to 10mm during commissioning to perfectly time the seating of heavy components.
Assembly Pressing
Leverage the 2513N pull force to securely seat parts while using the rear screw to compensate for mechanical tolerances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-10 the Right Cylinder?
Choose this 80mm bore when a 50mm bore (offering 825N pull at 0.5MPa) lacks the required thrust. The 10mm adjustment range is ideal for variable end-stops or product changeovers, whereas a fixed-stroke SAI locks you into one exact dimension. For any load holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is a travel stop, not a lock.

- ✓ 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 SAIJ80X140-10 FAQ
At 0.5MPa it provides 2513N pull and 3518N push, reaching 4523N push at 0.9MPa.
The rear adjuster allows you to shorten the 140mm nominal stroke by up to 10mm, creating a 130-140mm usable travel window for fine-tuning the end position.
