About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-20
The AirTAC SAIJ200X475-20 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a 475 mm nominal stroke paired with a 20 mm rear adjusting screw, creating a precise usable travel window of 455 to 475 mm. This allows you to dial in the retract position at commissioning without swapping out the cylinder or adding external stops.
The extruded aluminum barrel includes sensor grooves on both sides, and the carbon steel rod features an M36x2 thread. It operates at 30-500 mm/s with PT threaded G3/4 ports and variable air cushions at both ends to manage heavy kinetic energy.

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 SAIJ200X475-20 Is Used
Heavy Press Tuning
Fine-tune the 455-475 mm retract position during heavy press commissioning to achieve exact material forming depths without machining new spacers.
Product Line Changeover
Quickly adjust the end-stop by up to 20 mm when switching between product sizes on a high-force assembly line, minimizing downtime.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-20 the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires extreme force alongside variable end-stop positioning. If your setup actually needs less thrust, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, which might better suit medium-heavy loads without wasting air volume. Because the 475 mm stroke is substantial, always support the load with an external guide to prevent excessive side-loading on the M36x2 carbon steel rod.
Choose this adjustable SAIJ model over a fixed-stroke SAI when you anticipate product-size changes on your line and need rapid changeover capabilities. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold the load without live air pressure. For true pneumatic load-holding, you would need to integrate an external rod lock or switch to an AirTAC SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ200X475-20 FAQ
At its maximum rated pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stopper that lets you shorten the effective stroke from its 475 mm nominal length down to 455 mm. This creates a 455-475 mm travel window for fine-tuning the end position at commissioning, but it does not lock the load without continuous air pressure.
