About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX325-10S
The AirTAC SAIJ80X325-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 25 mm bore with a 325 mm nominal stroke that can be dialed back by up to 10 mm, yielding a precise 315-325 mm usable travel window for commissioning flexibility. Delivering 2513 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
This adjustable variant uses an external stopper at the retract end to fine-tune the end position without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Note that the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX325-10S Is Used
Machine Setup & Changeover
Dial in the exact 315-325 mm end position during commissioning or product-size changes without physically swapping cylinders.
Variable End-Stop Positioning
Provides a adjustable retract stop on a packaging line to accommodate different carton sizes on the fly.
High-Force Assembly Station
Leverages 2513 N of push force at 0.5 MPa for pressing operations while fine-tuning the travel end to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX325-10S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires 2513 N of push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559 N. The 10 mm adjustment window is ideal for variable end-stops or product-size changeovers, preventing the need to swap out a fixed-stroke SAI cylinder. Because the stroke is 325 mm, an external guide is recommended to support the rod and prevent excessive side-loading.
For ISO 15552 replacement matching, ensure the bore is 80 mm, stroke is 325 mm, adjustment is 10 mm, port is PT tapered, and the magnet option (-S) is present for sensor tracking. If true load-holding without live air pressure is required, consider the SAIL or BSAI series instead of relying on the rear adjuster.
Quick checklist
- ✓ 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 SAIJ80AX325-10S FAQ
It features a rear adjuster screw that acts as a mechanical stop, allowing you to shorten the 325 mm nominal stroke by up to 10 mm. This creates a 315-325 mm usable travel window for fine-tuning end positions. The adjuster is a stop, not a lock, and cannot hold the load without continuous air pressure.
At 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. The operating speed range is 30-800 mm/s. It uses a G3/8 port and includes a SUS420J2 stainless steel rod with an M20x1.5 thread.
