About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-40S
The AirTAC SAIJ160X135-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. Equipped with a SUS304 stainless steel rod (option B), it is built for corrosive environments and includes a magnet for CMSE reed and DMSE electronic sensors.
The integrated rear stopper allows you to fine-tune the effective travel down to a 95 mm minimum from the 135 mm nominal stroke, creating a 95-135 mm usable window. This mechanism acts purely as a travel stop to set end positions and does not hold the load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 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 SAIJ160 Adjustable Cylinder SAIJ160BX135-40S Is Used
Heavy Press Toning
Dial in the exact 95-135 mm travel during setup to accommodate varying material thicknesses in heavy pressing applications.
Line Changeover
Adjust end positions rapidly on the factory floor for new product sizes without physically replacing the cylinder.
Washdown Handling
Leverage the SUS304 rod for corrosive environments while using the rear stopper to tune the retraction point.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-40S the Right Cylinder?
The adjustable 40 mm travel window is ideal for product changeovers, letting you dial in the exact end-stop during commissioning without adding external stops or swapping a fixed-stroke SAI cylinder. For load-holding without continuous air, consider an external rod lock or the SAIL series instead of relying on this adjuster.
This SKU specifies PT tapered ports and the -S magnet option. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the 135 mm stroke is below the 300 mm threshold, side-load risks are minimal, but the robust 40 mm rod still handles lateral stress better than smaller bores.
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 SAIJ160 Adjustable Cylinder SAIJ160BX135-40S FAQ
At 0.9 MPa, the push force increases to 18095N.
The rear adjuster screw lets you shorten the 135 mm nominal stroke by up to 40 mm, creating a usable travel window of 95-135 mm. This stopper only sets the end position and does not lock the load without live air.
