About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-10
The AirTAC SAIJ200X325-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It yields a usable travel window of 315-325 mm, allowing you to dial back the 325 mm nominal stroke by up to 10 mm. At 0.5 MPa it generates 15708 N of push force and 15080 N of pull force, scaling up to 28274 N at its 0.9 MPa operating ceiling.
This heavy-duty actuator features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification. The rear stopper lets you fine-tune the retract end-position at commissioning without swapping the cylinder.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-10 Is Used
Heavy Pressing Operations
Utilizes the 15708 N push force at 0.5 MPa for forming and stamping, with the 10 mm adjuster allowing precise bottoming-out tuning without external mechanical stops.
Large Assembly Tooling
Employs the SUS304 stainless rod in harsh industrial environments, providing reliable actuation for large fixture clamping where exact end-positioning is dialed in during commissioning.
Product Line Changeover
Leverages the 315-325 mm travel window to quickly adapt machinery to slightly different product sizes, reducing downtime by adjusting the cylinder stroke on the machine rather than replacing hardware.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX325-10 the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when your application requires extreme force that smaller bores cannot provide, such as heavy pressing or large load manipulation. If the full 28274 N push force at 0.9 MPa is excessive, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. Conversely, if you need even more power, you would leave the SAIJ range behind. The adjustable 10 mm travel window is chosen over a fixed-stroke SAI cylinder when precise end-position tuning is required during machine setup or product changeover.
Because the 325 mm stroke creates a long lever arm, the 40 mm rod diameter and M36x2 thread still require an external guide to handle side loads safely. For ISO 15552 replacement matching, verify the 200 mm bore, 325 mm stroke, 10 mm adjustment, PT G3/4 port, and mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the AirTAC BSAI clamp-lock series.
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 SAIJ200BX325-10 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 325 mm nominal stroke by up to 10 mm, creating a 315-325 mm travel window. It fine-tunes the retract end position but does not lock the load without live air pressure.
