About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-30S
The AirTAC SAIJ200X475-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. This eliminates the need to physically swap the cylinder or bolt on external stops when fine-tuning the retract end position.
Equipped with a standard carbon steel rod and a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed neatly within the dual-side extruded aluminum barrel grooves. The rear adjuster functions strictly as a travel stop for deceleration and end-position setting; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X475-30S Is Used
Heavy Press End-Position Tuning
Dial in the exact retract distance within the 445-475mm window during setup to accommodate varying material thicknesses without changing out the actuator.
Product-Size Changeover
Quickly adjust the stroke stop on packaging lines when switching to different carton sizes, using the rear screw to set new travel limits on the fly.
Large Assembly Machine Setup
Fine-tune the end-stop during initial commissioning of heavy machinery, ensuring precise mating of large components without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-30S the Right Cylinder?
The integrated 30mm adjustment range is ideal for product-size changeovers on a line, allowing operators to set variable end stops rapidly without replacing the entire actuator.
This SKU uses a PT tapered port thread (G3/4) and the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the 475mm stroke is substantial, the M36x2 rod and carbon steel piston are subject to deflection under high side loads; an external guide mechanism is strongly recommended to prevent premature wear. For true ISO 15552 replacement matching, ensure your target footprint accommodates this bore, 475mm stroke, 30mm adjustment, PT port, and -S magnet configuration.

- ✓ 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 SAIJ200X475-30S FAQ
At the maximum operating pressure of 1.0MPa, it delivers up to 3204kgf.
The rear adjuster acts as a mechanical stop that can shorten the effective travel from the 475mm nominal stroke down to 445mm. It allows for fine end-position tuning at commissioning without swapping cylinders, but it does not lock or hold the load without continuous air pressure.
