About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-75
The AirTAC SAIJ32X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 115 mm stroke and a 75 mm adjustment range, you can dial the effective travel back to anywhere within a 40 to 115 mm window. This allows precise end-position tuning at commissioning without adding external stops.
This model is configured with an SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The barrel is an extruded aluminum profile with sensor grooves on both sides, and it omits tie-rod construction. It features PT tapered port threads (G1/8) and variable air cushions at both ends to decelerate the load. The rear adjuster acts strictly as a travel stop, not a lock, so the cylinder cannot hold a 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 SAIJ32AX115-75 Is Used
Machine Setup & Changeover
Dial in the exact retract position during line changeovers without swapping out the physical cylinder or adding external mechanical stops.
Variable End-Stop Positioning
Adjust the travel window from 40 to 115 mm on the fly to accommodate different part sizes or feeding distances on a single fixture.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX115-75 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires fine-tuning the retract end-position during machine setup or product changeover. Because the adjustment range is large (75 mm), you can use a single SKU to accommodate multiple varying stroke lengths within that 40-115 mm window. For holding a load safely without continuous air pressure, select a SAIL or BSAI locking cylinder instead, as the SAIJ adjuster is only a stop. To match this exact configuration for an ISO 15552 replacement, specify the 32 mm bore, 115 mm stroke, 75 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet.

- ✓ 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 SAIJ32AX115-75 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 115 mm down to as little as 40 mm, giving a usable window of 40-115 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air.
