About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-30
The AirTAC SAIJ200X500-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty pneumatics. The integrated -30 adjustment code provides a 470-500mm usable travel window, allowing you to dial in the exact retract position without swapping out the entire unit.
This 200mm bore profile cylinder features a robust 40mm carbon steel rod with M36x2 threads, designed to handle substantial side loads, though the 500mm stroke still necessitates an external guide to prevent rod deflection. It uses G3/4 PT tapered ports and includes variable air cushions at both ends to absorb kinetic energy. The rear stopper mechanism sets the travel end-point, but it does not lock the load; for dead-pilot pressure holding, consider the SAIL or BSAI series.

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 SAIJ200X500-30 Is Used
Heavy Pressing Operations
Dial in the exact 470-500mm end-stop during setup to ensure massive 28274N pressing force is applied consistently across varying workpiece heights.
Automated Line Changeover
Quickly adjust the retract position for different product sizes without physically replacing the cylinder or adding external mechanical stops.
Large Assembly Jigs
Handle heavy structural components using the 40mm carbon steel rod, relying on the integrated air cushions to safely decelerate the large moving mass.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-30 the Right Cylinder?
The adjustable 470-500mm travel window is ideal for product changeovers or fine-tuning end positions during machine commissioning, providing flexibility that a fixed-stroke SAI cylinder cannot match. Since this is a 500mm stroke, supporting the load with an external linear guide is highly recommended to manage side-load forces.
When specifying this ISO 15552 interchangeable cylinder, confirm the 200mm bore, 500mm stroke, 30mm adjustment, G3/4 PT port, and standard carbon steel rod. It supports the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) but omits FB, CA, CB, and CR brackets. Without a -S magnet option specified here, position sensing requires external methods rather than AirTAC CMSE or DMSE electronic switches.

- ✓ 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 SAIJ200X500-30 FAQ
At 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw allows you to shorten the 500mm nominal stroke by up to 30mm, creating a usable travel window of 470-500mm. This stopper sets the end position but does not lock the load without live air pressure.
