About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-50S
The AirTAC SAIJ200X65-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 15-65 mm, allowing you to dial back the 65 mm nominal stroke by up to 50 mm during commissioning. In the 200 mm bore class, it delivers immense thrust, generating 21991 N of push force and 15080 N of pull force at a 0.7 MPa operating pressure.
This specific configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid supply connects via PT tapered ports sized at G3/4.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-50S Is Used
Heavy Press Tuning
Dial in the exact 15-65 mm end-of-stroke position for heavy pressing and forming tasks during initial machine setup without external stopper blocks.
Product Changeover
Quickly adjust the retract stop on a packaging line to accommodate varying product sizes, using the 50 mm adjustment range to modify the travel window.
Large Assembly End-Stop
Set precise retraction limits for massive 200 mm bore assembly stations, relying on the 15080 N pull force at 0.7 MPa to move substantial jigs.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX65-50S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires 21991 N of push force at 0.7 MPa, stepping up considerably from the 160 mm bore which yields 14074 N. The adjustable stroke is ideal for product-size changeovers on a line, letting you fine-tune the end position without swapping the cylinder or adding external stops. If you need to step down force, the 160 mm bore offers 14074 N at the same pressure.
The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider the SAIL or BSAI series instead. Because this is an adjustable-stroke model, it uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 mounting-interface dimensions.
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 SAIJ200AX65-50S FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it reaches 3204 kgf.
The rear adjuster screw lets you shorten the 65 mm nominal stroke by up to 50 mm, creating a 15-65 mm usable travel window. The adjuster acts as a mechanical stop to set the retract end-position and is not a lock; it cannot hold the load without continuous air pressure.
