About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-75S
The AirTAC SAIJ160X135-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 60-135 mm from its 135 mm nominal stroke. The barrel features sensor grooves on both sides for direct mounting of CMSE reed and DMSE electronic switches.
This unit uses a SUS304 stainless steel rod for corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to fine-tune the retract position during commissioning without adding external stops. It is not a locking device and cannot hold a load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX135-75S Is Used
Heavy Press Tuning
Dial in the exact 60-135 mm end-position during machine commissioning to accommodate varying material thicknesses without swapping cylinders.
Product Changeover Stops
Adjust the retract stopper on the fly when switching the line to a different product size, ensuring precise physical positioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX135-75S the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeover. For load-holding without continuous air, select the SAIL or BSAI series instead, as the SAIJ adjuster only sets travel limits.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 135 mm stroke, 75 mm adjustment range, PT G3/4 port, and the -S magnet. Although the 135 mm stroke is under 300 mm, the large 40 mm rod and M36x2 thread handle high side loads well, though an external guide is recommended for heavy off-center 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 SAIJ160 Adjustable Cylinder SAIJ160BX135-75S FAQ
It can deliver up to 2050 kgf at 1.0 MPa.
The rear adjuster allows you to mechanically shorten the effective stroke by up to 75 mm, creating a 60-135 mm usable travel window. It functions as a physical stop for end-position tuning and does not lock or hold the load without live air.
