About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-20S
The AirTAC SAIJ160X350-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 330 to 350 mm. This bore features a robust 40 mm rod and a G3/4 port to efficiently handle high-volume airflow.
Built with a SUS304 stainless steel rod (option B), this version is tailored for environments demanding superior corrosion resistance. The integrated -S magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves. The rear stopper acts purely as a travel limit and does not function as a lock, meaning live air pressure is required to sustain the load.

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 SAIJ160BX350-20S Is Used
Machine Setup & Changeover
Dial in the exact end-of-stroke position within the 330-350 mm window during line changeovers without disassembling the actuator or adding external mechanical stops.
Variable End-Stop Positioning
Ideal for heavy-duty assembly stations where the retracted position needs occasional fine-tuning to accommodate varying product dimensions while maintaining high thrust.
Corrosive Environment Automation
The SUS304 stainless steel rod makes this adjustable cylinder well-suited for packaging or processing lines exposed to moisture, chemicals, or washdowns.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-20S the Right Cylinder?
The 20 mm rear adjustment screw is ideal for fine-tuning the end position during commissioning or product changeover, removing the need to physically swap cylinders or bolt on external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
When matching this for an ISO 15552 replacement, verify the 350 mm stroke, 20 mm adjustment range, PT tapered G3/4 port, and the -S magnet requirement. Because the 350 mm stroke is substantial, the long unsupported piston rod necessitates an external guide to prevent excessive side-loading and premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ160BX350-20S FAQ
The maximum thrust is 2050 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 20 mm, providing a usable stroke range of 330 to 350 mm. This stopper only limits travel and does not lock the load without live air pressure.
