About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10
The AirTAC SAIJ200X260-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. The integrated 10mm adjustment screw allows you to trim the effective travel back from the 260mm nominal stroke, creating a precise 250-260mm usable window to dial in final end positions during commissioning.
This heavy-duty actuator features a SUS420J2 stainless steel rod for enhanced durability against moisture and a G3/4 PT tapered port for high airflow. Unlike a fixed-stroke SAI cylinder, this adjustable variant eliminates the need to add external stopper blocks when product sizes change. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU is configured without a magnet for electronic or reed switches.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10 Is Used
Heavy Machinery Setup
Fine-tune the 250-260mm travel window during heavy machinery commissioning to achieve exact contact positioning without machining new spacer blocks.
Product Changeover
Quickly adapt a high-force press line for different product heights by dialing the rear adjuster screw up to 10mm instead of swapping cylinders.
Large Assembly Pressing
Leverage the 15708N push force at 0.5 MPa to seat large components, using the adjustable end-stop to prevent over-travel on delicate parts.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires extreme force (up to 3204kgf at 1.0 MPa) but still demands micro-adjustments to the retract end position. If you need slightly less force, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa. Because the 260mm stroke exceeds 300mm? No, but even at 260mm, an unsupported heavy load necessitates an external guide to prevent side-loading damage to the 40mm rod and M36x2 thread.
This model uses PT tapered ports and supports the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without continuous air pressure. For true load-holding, consider an external rod lock or the AirTAC SAIL series. To replace an ISO 15552 cylinder, match the 200mm bore, 260mm stroke, 10mm adjust, G3/4 PT port, and mounting hardware.
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 SAIJ200AX260-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 260mm nominal stroke by up to 10mm. This creates a 250-260mm usable travel window for fine-tuning the end position without needing live air to hold the load.
