About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-40
The AirTAC SAIJ32X115-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits precise end-position tuning. It provides a usable travel window of 75 to 115 mm, enabling you to shorten the effective stroke by up to 40 mm during commissioning without adding external stops.
Equipped with an SUS420J2 stainless steel rod, this unit handles demanding environments while maintaining the standard ISO 15552 mounting interface. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Variable air cushions at both ends manage end-of-stroke deceleration, while the rear adjuster acts purely as a mechanical stop rather than 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 SAIJ32AX115-40 Is Used
Machine Changeover
Dial in the 75-115 mm travel window during product size transitions without physically swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the exact retract distance during initial commissioning to perfect the pickup or placement of delicate components.
Variable End Stops
Adjust the effective stroke on the fly for multi-format assembly lines that require slightly different retraction distances per fixture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-40 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires exact end-stop calibration or frequent product changeovers. Because the stroke is under 300 mm, side-load risks are minimal, though external guides remain recommended for heavy lateral loads.
To match this ISO 15552 cylinder for a replacement, verify the 32 mm bore, 115 mm nominal stroke, 40 mm adjustment range, PT port thread, and the absence of a magnet. Remember that the rear adjuster and air cushions only set travel limits; they do not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.
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 SAIJ32AX115-40 FAQ
At the maximum pressure of 1.0 MPa, it delivers up to 80 kgf.
The rear adjuster screw lets you mechanically shorten the 115 mm nominal stroke by up to 40 mm, creating a usable travel window of 75 to 115 mm. The adjuster functions as a physical stop and does not lock or hold the load without live air.
