About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10S
The AirTAC SAIJ32X325-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 325 mm nominal stroke that can be dialed back by up to 10 mm, creating a precise 315-325 mm usable travel window for fine-tuning end positions during commissioning. Delivering 402 N of push force at 0.5 MPa, it integrates an SUS420J2 stainless steel rod and a magnetic piston for position sensing.
This model uses PT tapered ports and achieves speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options for streamlined profile integration. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10S Is Used
Machine Changeover
Dial in the exact 315-325 mm end position during product size changes without physically swapping the cylinder or bolting on external stoppers.
End-Position Tuning
Fine-tune the retract stroke by up to 10 mm at commissioning to perfect the seating of a 32 mm bore actuator pushing 402 N at 0.5 MPa.
Variable End Stops
Adjust the travel window on a packaging line to handle slightly different package lengths without reprogramming the entire motion controller.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX325-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa (or 724 N at 0.9 MPa) within a variable 315-325 mm travel range. If you need less force, stepping down is not an option in this series, but stepping up to a 40 mm bore yields 628 N. The adjustable stroke is ideal for machine changeovers, allowing you to trim the end-stop without swapping cylinders or adding external stops. For stroke lengths of 325 mm, the 12 mm rod and M10x1.25 thread handle moderate side loads, but an external guide is recommended for unsupported loads. To replace an ISO 15552 cylinder, match the 32 mm bore, 325 mm stroke, 10 mm adjustment, PT ports, and the -S magnet.
Because the rear adjuster and air cushions only decelerate the travel end, this cylinder will not hold a load without live air. For true fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead of relying on the SAIJ stopper.
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 Adjustable Cylinder SAIJ32 SAIJ32AX325-10S FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 325 mm nominal stroke by up to 10 mm, resulting in a 315-325 mm usable travel window. It only sets the travel end and does not lock the load without live air pressure.
