About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-30S
The AirTAC SAIJ200X55-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed for heavy-duty applications requiring exact end-position tuning. The integrated -S magnet enables position sensing via AirTAC CMSE reed and DMSE solid-state electronic switches housed in the dual-side sensor grooves.
With a nominal 55mm stroke and a 30mm adjustment range, this model provides a usable travel window of 25-55mm, allowing you to dial in the exact end-stop during commissioning without adding external stops. It features a robust 40mm carbon steel piston rod and PT tapered ports. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold the load without live air pressure.

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 SAIJ200X55-30S Is Used
Heavy Press Tuning
Dial in the exact 25-55mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping cylinders.
Assembly Line Changeover
Rear screw adjustment allows rapid end-position modifications during product changeovers, replacing the need for fixed external stops on the assembly line.
Automated Clamping
Provides massive 15708N clamping force at 0.5 MPa while allowing operators to fine-tune the clamping depth precisely for different part geometries.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-30S the Right Cylinder?
Select this 200mm bore cylinder when your application requires massive force—up to 15708N at 0.5 MPa—and precise variable end-stops. The adjustable stroke is ideal for machine setups requiring frequent product-size changeovers, offering fine-tuning that a fixed-stroke SAI cylinder cannot match. Because the nominal stroke is 55mm, side-loading risks are minimal, but the 40mm rod and M36x2 thread handle high axial loads effectively.
For ISO 15552 dimensional interchangeability, match the 200mm bore, 55mm stroke, 30mm adjustment, PT port thread, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). If your application requires true load-holding without live air pressure, this cylinder's stopper is insufficient; consider an external pilot-operated check valve or AirTAC SAIL and BSAI locking cylinders instead.

- ✓ 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 SAIJ200X55-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30mm. This creates a usable travel window of 25-55mm from the 55mm nominal stroke, enabling fine end-position tuning without external stops.
The maximum thrust is 3204 kgf at 1.0 MPa.
