About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10S
The AirTAC SAIJ200X260-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the end position. The 10mm adjustment code creates a usable travel window between 250 and 260mm, allowing precise positioning without adding external stops. Equipped with a SUS420J2 stainless steel rod and a PT tapered port, it delivers 15708N of push force at 0.5MPa and 21991N at 0.7MPa.
This unit includes a magnet for use with CMSE reed and DMSE electronic sensors, fitting neatly into the dual-side sensor grooves of the extruded aluminum barrel. The 40mm rod diameter and M36x2 thread provide substantial rigidity, while the 50mm variable air cushion at both ends manages deceleration across its 30-500mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10S Is Used
Heavy Press Tuning
Dial in the exact 250-260mm end position for heavy pressing tasks, ensuring perfect contact force without physically altering the machine frame.
Product Changeover
Quickly accommodate varying workpiece sizes on a single line by trimming the stroke up to 10mm at the rear, bypassing the need to bolt on external stoppers.
Large Assembly End-Stops
Establish a precise, repeatable travel limit for large-scale assembly stations where the 15708N thrust at 0.5MPa is required to move substantial masses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX260-10S the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires the highest thrust classes, stepping up significantly from the 100mm bore which yields 3927N at 0.5MPa. An adjustable stroke is chosen over a fixed SAI cylinder when machine setups require variable end-stops or product changeovers need rapid reconfiguration without physically swapping the actuator. To match this ISO 15552 replacement, specify bore 200, stroke 260, 10mm adjustment, PT port, and the -S magnet.
Because the nominal stroke is 260mm, an external guide is recommended to prevent excessive side-load on the rod. Remember that the rear adjuster acts solely as a mechanical stop; it does not hold the load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ200AX260-10S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 260mm down to 250mm. This creates a 250-260mm usable window for fine-tuning the end position at commissioning, but it does not lock or hold the load without live air pressure.
