About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX250-10
The AirTAC SAIJ200X250-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position. Based on the 250mm nominal stroke and the 10mm adjustment code, it provides a usable travel window of 240-250mm. Belonging to the 200mm bore class, it generates a substantial thrust of 15708N and a pull force of 15080N at 0.5MPa, making it suitable for moving heavy loads.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, though position detection requires adding a magnet separately. The rear adjuster acts purely as a mechanical stop to dial in the retract position during commissioning without adding external stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX250-10 Is Used
Heavy Machinery Setup
Dial in the exact 240-250mm retract position during heavy machinery commissioning without swapping cylinders or adding external stopper blocks.
Product Changeover
Adjust the end-stop by up to 10mm on a production line to accommodate slight variations in large product sizes.
High-Force Positioning
Leverage the 15708N push force to move heavy pallets or industrial fixtures while fine-tuning the landing position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX250-10 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires up to 15708N of push force at 0.5MPa and a highly precise retract end-point. If your force requirements are lower, stepping down to the 160mm bore yields 10053N of thrust, while the 200mm bore is necessary for heavy-duty positioning. The 10mm adjustable window is ideal for applications needing minor commissioning tweaks rather than large travel changes. For fixed travel without the adjuster, the standard SAI series is a simpler alternative.
When replacing an ISO 15552 cylinder, match the 200mm bore, 250mm stroke, PT tapered port thread, and the required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this cylinder operates at 30-500mm/s. Because the stroke is 250mm, ensure external guiding is used to handle side loads, as even the robust M36x2 rod thread and 40mm rod diameter cannot support high lateral forces alone. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air pressure, use an external rod lock or explore the SAIL or BSAI 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 SAIJ200AX250-10 FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides a push (thrust) force of 15708N and a pull force of 15080N. At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from the nominal 250mm down to 240mm. This creates a 240-250mm travel window for fine-tuning the retract end position during setup. The adjuster is a stop, not a lock, and cannot hold the load without live air pressure.
