About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-20S
The AirTAC SAIJ200X350-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers immense thrust, pushing 15708 N at 0.5 MPa, making it suited for heavy-duty automation. The built-in -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors for precise end-position detection.
The -20 adjustment code creates a usable travel window of 330-350 mm. This lets you fine-tune the retract end-position at commissioning without adding external stops. The barrel is extruded aluminum with sensor grooves on both sides, and the rod uses SUS420J2 stainless steel for corrosion resistance.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-20S Is Used
Heavy Pressing Operations
Dial in the exact 330-350 mm end-stop for heavy pressing tasks, ensuring precise force application without physically swapping cylinders.
Product Size Changeovers
Adapt a long-stroke conveyor diverter on the fly by trimming the travel by up to 20 mm to accommodate varying package lengths.
Machine Commissioning
Fine-tune the retract position during initial machine setup to perfectly align heavy tooling, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX350-20S the Right Cylinder?
Choose this 200 mm bore when you need maximum push force up to 15708 N at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The adjustable 330-350 mm travel is ideal for product changeovers requiring variable end-stops. Because the 350 mm stroke is substantial, an external guide is recommended to handle side loads on the 40 mm rod.
This SAIJ model uses PT tapered ports (G3/4) and supports the SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts only as a travel stop, not a lock; for load-holding without live air, select a SAIL or BSAI cylinder instead.
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 SAIJ200 Adjustable Cylinder SAIJ200AX350-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can achieve a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 350 mm stroke by up to 20 mm, providing a usable travel window of 330-350 mm. It functions as an end-position stop for fine-tuning, not as a load-holding lock.
