About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-75S
The AirTAC SAIJ32X135-75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 135 mm stroke that can be dialed back by up to 75 mm, creating a wide 60-135 mm usable travel window for highly flexible positioning.
This variant features an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed or DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a mechanical stop to set deceleration, not to 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 SAIJ32AX135-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 60 and 135 mm for multi-format packaging lines that process different carton sizes on the same machine.
Machine Setup & Commissioning
Fine-tune the final end position during initial rigging to compensate for mechanical tolerances without machining new hard stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-75S the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning during commissioning or product changeover without swapping the cylinder or adding external stops. Because the stroke is 135 mm, no external side-load guide is strictly required, though the 12 mm rod and M10x1.25 thread handle standard loads well.
The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). For exact ISO 15552 replacement matching, verify the 135 mm stroke, 75 mm adjustment, PT tapered port threads, and the -S magnet. Remember that the rear adjuster is a travel stop, not a lock; for true fail-safe load holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ32AX135-75S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to mechanically shorten the effective stroke from its 135 mm nominal length down to 60 mm. This stopper sets the travel end and deceleration point but does not lock or hold the load without continuous air pressure.
