About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-75
The AirTAC SAIJ200X475-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. A carbon steel piston rod with an M36x2 thread provides a robust interface for heavy-duty tooling, while the extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This model provides a usable travel window of 400-475 mm, allowing you to dial back the nominal 475 mm stroke by up to 75 mm. The rear adjustment screw lets you fine-tune the end position at commissioning or during product changeover without adding external stops. It uses a G3/4 port and includes variable air cushions at both ends, each offering 50 mm of cushioning to decelerate massive loads smoothly.

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 SAIJ200X475-75 Is Used
Heavy Press Tuning
Dial in the exact 400-475 mm end position during press commissioning to accommodate different die heights without machining new spacers.
Product Changeover
Quickly adjust the stroke stop on packaging lines when shifting between large container sizes, reducing setup downtime significantly.
Variable End Stops
Use the 75 mm adjustment range to set precise retraction points for heavy material handling arms without installing external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-75 the Right Cylinder?
The adjustable 400-475 mm travel is ideal for variable end-stop requirements, eliminating the need to swap cylinders for different product sizes. Because the stroke is 475 mm, an external guide is recommended to prevent excessive side-load on the M36x2 rod.
For an exact ISO 15552 replacement, match the 200 mm bore, 475 mm stroke, 75 mm adjustment, PT tapered port threads, and basic mounting setup. Note that this SAIJ variant supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ200X475-75 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf of push force.
The rear adjuster screw allows you to shorten the effective travel from the nominal 475 mm down to 400 mm, giving a usable window of 400-475 mm for fine-tuning the retract end position without swapping the cylinder.
