About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-40
The AirTAC SAIJ32X85-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 45 to 85 mm. It features a SUS420J2 stainless steel rod for improved corrosion resistance and utilizes PT tapered port threads.
The rear adjustment mechanism acts strictly as a mechanical stop to fine-tune the end position during commissioning; it does not lock the load without continuous air pressure. For load-holding requirements without live air, consider an SAIL or BSAI variant. This model supports a speed range of 30-800 mm/s and offers the standard SAIJ mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ32AX85-40 Is Used
Machine Changeover
Dial in the 45-85 mm travel window during product size changes without machining new hard stops or replacing the actuator.
End-Stop Calibration
Fine-tune the retract position at commissioning using the rear adjuster to achieve precise mechanical spacing.
Variable Pitch Indexing
Accommodate varying material lengths on a line by adjusting the stroke back up to 40 mm to meet exact process requirements.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX85-40 the Right Cylinder?
Conversely, lighter duties can be handled by smaller variants. The generous 40 mm adjustment range is ideal for product changeovers, replacing the need for fixed-stroke SAI cylinders when exact end-stops fluctuate between fixtures.
When specifying your replacement, verify the 85 mm stroke, 40 mm adjustment range, PT port threads, and the absence of a magnet (-S). Because this unit lacks a magnet, it cannot host CMSE or DMSE sensors without modification. The SUS420J2 rod material offers a good balance of strength and corrosion resistance, though long unsupported strokes still require external guiding to prevent side-loading wear.
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 SAIJ32AX85-40 FAQ
It features a rear mechanical stopper that allows you to reduce the 85 mm nominal stroke by up to 40 mm, creating a usable travel window of 45 to 85 mm. This lets you set the exact retract end-position during setup without adding external stops.
The maximum thrust is 82 kgf at 1.0 MPa.
