About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-40
The AirTAC SAIJ200X500-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. By turning the rear stopper, you achieve a usable travel window of 460-500mm, enabling precise end-position tuning during commissioning without adding external stops.
This heavy-duty actuator operates at 30-500mm/s and includes variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel integrates dual sensor grooves, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 attachments. The PT (tapered) G3/4 ports ensure high airflow for rapid cycling.

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 SAIJ200X500-40 Is Used
Heavy Press Tuning
Dial in the exact 460-500mm travel window during heavy press commissioning to accommodate varying material thicknesses without external stopper blocks.
Large Conveyor Diverters
Adjust the retract position on the fly during product size changeovers, ensuring bulky items are accurately routed without remounting the cylinder.
Automated Assembly Stops
Fine-tune the end-of-stroke position for large assembly jigs, using the rear stopper to set precise mechanical limits for heavy fixtures.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-40 the Right Cylinder?
The 40mm adjustment range is ideal for product changeovers on large machines, allowing you to dial in the exact 460-500mm stroke without swapping hardware. For any 500mm stroke, an external guide is strongly recommended to prevent side-load damage to the 40mm rod.
If the application requires holding a load without live air pressure, a plain SAIJ cannot perform this function. The rear adjuster acts only as a travel stop, not a brake. For true load-holding, select the SAIL (air-released lock) or BSAI (clamp-lock) series instead. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ200X500-40 FAQ
At the maximum pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 500mm nominal stroke by up to 40mm. This creates a usable travel window of 460-500mm, allowing precise end-position tuning without swapping the cylinder.
