About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-30S
The AirTAC SAIJ32X155-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 125-155 mm, allowing you to dial back the 155 mm nominal stroke by up to 30 mm during commissioning.
This unit features a SUS304 stainless steel rod (option B) for superior corrosion resistance in washdown or chemically active settings. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet supports position detection via AirTAC CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a travel stop for end-position tuning, not as a load-holding lock.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32BX155-30S Is Used
Machine Setup and Changeover
Dial in the 125-155 mm travel window during product size changes, using the rear stopper to fine-tune the end position without adding external shims.
Sensor-Ready Automation
Utilize the dual sensor grooves and built-in magnet to mount CMSE reed or DMSE electronic switches for precise mid-stroke or end-position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-stop tuning without swapping cylinders; if you need higher thrust, stepping up to the 40 mm bore yields 528 N of pull force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on packaging lines where the exact end position varies by a few millimeters. Because the rear screw is only a stop, load-holding without live air requires a separate SAIL pneumatic lock or external rod lock. For ISO 15552 replacement matching, specify a 32 mm bore, 155 mm stroke, 30 mm adjustment, PT tapered port, and the -S magnet option. The 12 mm rod and M10x1.25 thread handle moderate side loads, though any stroke over 300 mm would require an external guide.
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 SAIJ32BX155-30S FAQ
It can reach a maximum thrust of 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 155 mm nominal stroke by up to 30 mm. This creates a usable travel window of 125-155 mm for fine-tuning end positions without replacing the cylinder.
