About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-75S
The AirTAC SAIJ200X300-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers immense thrust, pushing 15708N and pulling 15080N at 0.5 MPa, making it suited for heavy-duty industrial motion. The integrated -S magnet pairs directly with CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves.
This specific SKU provides a nominal 300mm stroke that can be fine-tuned backward by up to 75mm, creating a precise 225-300mm usable travel window. The adjustment is achieved via an external stopper at the retract end, enabling exact end-position calibration during commissioning without adding external stops. It features a robust 40mm carbon steel rod and a G3/4 PT port.

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 SAIJ200X300-75S Is Used
Heavy Press Tuning
Dial in the exact 225-300mm travel window during heavy press commissioning to accommodate varying material thicknesses without swapping out the main actuator.
Product Changeover Stops
Adjust the retract end-position on the fly during packaging line product size changes, ensuring bulk items are halted at the precise transfer point.
Large Assembly Calibration
Fine-tune the end-of-stroke position for large automotive or heavy equipment assembly stations, accommodating fixture variations directly at the machine.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X300-75S the Right Cylinder?
An adjustable stroke is preferred over a fixed SAI cylinder when you need to dial in the travel window during machine setup or product changeovers. Remember that the rear adjuster functions strictly as a travel stop, not a lock; this plain SAIJ will not hold a load without live air, so for fail-safe load holding, consider an SAIL or BSAI cylinder.
Because the 300mm stroke is substantial, the heavy 40mm rod and M36x2 thread still require an external guide to prevent excessive side-loading and premature seal wear. To match this ISO 15552 interchangeable cylinder exactly, specify a 200mm bore, 300mm stroke, 75mm adjustment, G3/4 PT port, a mounting set from Basic, FA, LB, TC, FTC, TCM1, or TCM2, and the -S magnet option.

- ✓ 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 SAIJ200X300-75S FAQ
It can deliver a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster acts as a stopper that lets you shorten the 300mm nominal stroke by up to 75mm, providing a 225-300mm usable travel window. This allows for fine-tuning the end position at commissioning without changing the cylinder itself.
