About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-100S
The AirTAC SAIJ32X155-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 55 to 155 mm. This compact bore size is tailored for applications demanding exact end-position tuning without swapping hardware.
The generous 100 mm adjustment range allows operators to dial in the retract stop during machine setup or product changeovers. It features sensor grooves on both sides of the extruded aluminum barrel, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

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 SAIJ32BX155-100S Is Used
Product Size Changeovers
Dial in the 55 to 155 mm travel window during production line changeovers to accommodate varying package sizes without replacing the cylinder.
Machine Setup Calibration
Fine-tune the retract end-position at commissioning using the rear stopper, preventing the need to bolt on external stops or machine new mounting plates.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX155-100S the Right Cylinder?
The SAIJ32X155-100-S is selected over a fixed SAI cylinder when a 55 to 155 mm variable end-stop is required for frequent line changeovers. Because the stroke is 155 mm, ensure external guiding if side loads are present.
For an exact ISO 15552 replacement match, verify the 32 mm bore, 155 mm nominal stroke, 100 mm adjustment range, PT port thread, and the -S magnet option. Remember that the rear adjuster only sets the travel end and is not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ32BX155-100S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window of 55 to 155 mm from the 155 mm nominal stroke. It functions as a mechanical stop for end-position tuning and is not a locking device.
