About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-20S
The AirTAC SAIJ160X170-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 150 to 170 mm. The integrated magnet works with CMSE reed and DMSE solid-state sensors for precise end-of-travel detection.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper allows fine end-position tuning during commissioning without adding external stops.

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 SAIJ160BX170-20S Is Used
Heavy Press Tuning
Dial in the exact 150-170 mm travel during heavy press setup to accommodate material thickness variations without replacing the cylinder.
Product Changeover
Quickly adjust the end-stop position on automated lines when switching between different product sizes, minimizing machine downtime.
Corrosive Assembly
Leverage the SUS304 stainless steel rod in humid or washdown assembly stations requiring high thrust and precise variable end positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX170-20S the Right Cylinder?
The adjustable stroke is ideal for product changeover, letting you dial in the exact 150-170 mm travel without swapping the cylinder.
For dimensionally interchangeable ISO 15552 replacements, match the 160 mm bore, 170 mm stroke, 20 mm adjustment, PT G3/4 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Since the stroke is 170 mm, ensure proper guiding to prevent excessive side-load on the rod. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use an external rod lock or pilot-operated check valve.
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 SAIJ160BX170-20S FAQ
The rear adjusting screw acts as a mechanical stopper that trims the retract end position, creating a usable travel window between 150 and 170 mm. This allows for fine-tuning at commissioning without changing the cylinder.
