About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10S
The AirTAC SAIJ160X325-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The integrated -S magnet enables position sensing with AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. Featuring an SUS304 stainless steel rod and PT tapered ports, it is tailored for demanding environments.
This model features a 325mm nominal stroke that can be fine-tuned down by up to 10mm, creating a usable travel window of 315-325mm. This built-in adjustability allows operators to dial in exact retract end-positions during commissioning without adding external stops. The rear screw acts purely as a travel stop to set the deceleration point alongside the adjustable air cushions; it is not a locking device and will not hold a load without continuous live air pressure.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10S Is Used
Heavy Machinery Setup
Fine-tune the 315-325mm retract position precisely during heavy machinery commissioning without swapping out the entire cylinder.
Product Size Changeover
Quickly adapt end-stops for varying product sizes on a production line using the 10mm rear adjustment screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX325-10S the Right Cylinder?
An adjustable-stroke model is ideal for applications requiring variable end-stops or product changeovers, providing setup flexibility that a fixed-stroke SAI cylinder cannot match. To replace an ISO 15552 cylinder, match the 160mm bore, 325mm stroke, 10mm adjustment, PT ports, and the -S magnet.
Because the 325mm stroke is relatively long, the 40mm rod diameter and M36x2 rod thread provide rigidity, but an external guide should be used to prevent excessive side-loading on the piston. For applications requiring the load to be held mechanically without air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ160 Adjustable Cylinder SAIJ160BX325-10S FAQ
The rear adjuster screw allows you to shorten the 325mm nominal stroke by up to 10mm, providing an effective travel window of 315-325mm. This stopper sets the end position but does not lock the load without live air pressure.
