About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-50
The AirTAC SAIJ200X375-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This built-in adjustability eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers.
Equipped with a robust 40mm carbon steel rod and M36x2 threading, this unit handles heavy loads while maintaining the standard ISO 15552 mounting interface. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU omits the magnet. Note that the rear adjuster functions strictly as a travel stop to set the retraction end-point, not as a locking device to 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 SAIJ200X375-50 Is Used
Heavy Press Tuning
Dial in the exact 325-375mm end-stop position during heavy press commissioning to accommodate material thickness variations without swapping hardware.
Product Size Changeover
Quickly adjust the retraction point on automated lines when switching between different product sizes, leveraging the 50mm trim range.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-50 the Right Cylinder?
The adjustable 50mm travel window is ideal for setups requiring precise end-position tuning without machining custom spacers.
Because the 375mm stroke is substantial, the 40mm rod will experience leverage forces; an external guide is recommended to prevent side-loading damage. To replace an ISO 15552 cylinder, match the 200mm bore, 375mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). For applications needing true load-holding without continuous air pressure, consider the SAIL or BSAI variants instead of relying on this adjuster.
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 SAIJ200X375-50 FAQ
The rear adjuster acts as a mechanical stopper, allowing you to shorten the nominal 375mm stroke by up to 50mm. This creates a usable travel window of 325-375mm, enabling fine-tuning of the end position without adding external stops.
At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
