About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-75S
The AirTAC SAIJ32X115-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 115 mm travel that can be dialed back by up to 75 mm, giving you a flexible 40-115 mm usable stroke window. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Equipped with a magnet for position sensing, this model works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting. It features PT tapered port threads (G1/8) and uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

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 SAIJ32AX115-75S Is Used
Machine Setup Changeover
Dial in the exact end position from 40 to 115 mm during product format changes without physically remounting the cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Perfect for assembly lines where the effective stroke needs on-the-fly adjustments to accommodate varying part sizes, using the rear screw to fine-tune the travel limit.
Sensor-Equipped Testing
Leverage the integrated magnet and dual sensor grooves to confirm end-of-travel positions with CMSE or DMSE switches while adjusting the stroke window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-75S the Right Cylinder?
If your application requires less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore increases your push force to 628 N. The adjustable stroke is perfect for machine setups requiring frequent product changeovers, replacing fixed-stroke SAI cylinders when exact travel distances vary.
When selecting, remember the rear adjuster acts only as a travel stop and deceleration aid, not a lock. A plain SAIJ does not hold its load without live air pressure; for true load-holding without continuous air, consider the SAIL (air-released lock) or BSAI (clamp-lock) series. The 12 mm rod and M10x1.25 thread handle moderate side loads, but for this 115 mm stroke, an external guide is recommended if carrying heavy lateral loads.
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 SAIJ32AX115-75S FAQ
At 0.7 MPa, the push force increases to 563 N.
The rear adjusting screw acts as an external stopper that lets you shorten the effective travel from the nominal 115 mm down to as little as 40 mm. This creates a 40-115 mm adjustable window for fine-tuning the retract end position at commissioning, but it does not lock the load without live air.
