About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10S
The AirTAC SAIJ200X145-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 145 mm stroke that can be fine-tuned down by up to 10 mm, giving operators a precise 135-145 mm usable travel window during commissioning. Built to deliver immense thrust, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. Fluid control is managed via PT tapered ports sized at G3/4, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 135-145 mm end position during heavy press commissioning to accommodate material thickness variations without external stops.
Product Size Changeover
Quickly adjust the stroke by up to 10 mm on automated lines when switching between different large-scale product dimensions.
High-Force Positioning
Leverage the 15708 N push force at 0.5 MPa to move and position heavy industrial components with precise end-stop control.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-10S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme force, stepping up significantly from the 160 mm bore which provides 10053 N push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on heavy machinery, allowing you to dial in the exact end-of-stroke position without swapping cylinders or adding external stops. Mounting options include the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For any stroke of 300 mm or more, an external guide is recommended to manage side-load, though this 145 mm unit is well within standard unsupported limits. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air. For dead-load holding, consider an external rod lock or the AirTAC SAIL series. To match this ISO 15552 interchangeable cylinder exactly, specify: 200 mm bore, 145 mm stroke, 10 mm adjustment, PT ports, SUS420J2 rod, and the -S magnet.

- ✓ 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 SAIJ200AX145-10S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 10 mm, creating a 135-145 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
