About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-30
The AirTAC SAIJ32X135-30 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 30 mm, creating a precise 105-135 mm usable travel window for commissioning flexibility.
This unit is built with a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads (G1/8). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches, though no magnet is installed on this specific configuration. The rear adjuster acts purely as a travel stop to decelerate the load, not as a 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 SAIJ32AX135-30 Is Used
Machine Changeover
Quickly fine-tune the retract end position by up to 30 mm when switching between product sizes on a packaging line, eliminating the need for custom spacer rings.
End-Stop Calibration
Dial in the exact 105-135 mm travel window during initial commissioning to perfect a pressing or forming operation without machine redesign.
Variable Positioning
Provide a adjustable physical stop for sensitive component placement tasks where the final resting position must be tweaked on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX135-30 the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires exact end-position tuning at setup or during product changeovers without physically swapping the cylinder or adding external stops. If your machine needs slightly less travel than a fixed 135 mm SAI offers, the 30 mm adjustment window lets you dial it in perfectly.
Because the nominal 135 mm stroke is under 300 mm, side-load stress on the M10x1.25 rod thread is moderate, but an external guide is still recommended for heavy lateral loads. Remember that the rear adjuster only sets the travel end; it does not hold the load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series. This SAIJ model supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

- ✓ 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 SAIJ32AX135-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from 135 mm down to as little as 105 mm. It sets the travel end and works with the air cushion to decelerate the load, but it does not lock the position without live air pressure.
