About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100S
The AirTAC SAIJ200X650-100-S is a double-acting ISO 15552 profile cylinder featuring a 200mm bore and a 650mm nominal stroke. Equipped with a rear adjusting screw, it provides a usable travel window of 550 to 650mm, allowing you to dial back the extend position by up to 100mm without swapping the cylinder or adding external stops. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at 0.5MPa, making it ideal for heavy-duty positioning.
This variant includes a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions strictly as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100S Is Used
Heavy Press Assembly
Dial in the exact 550-650mm extend position during heavy press assembly to accommodate varying material thicknesses without repositioning the entire fixture.
Variable End-Stop Positioning
Set precise end-stops on large automated machinery, allowing operators to trim the stroke back by up to 100mm during product changeovers.
Machine Commissioning
Fine-tune the travel endpoint at machine commissioning to avoid mechanical crashes, using the rear adjuster rather than installing external physical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-100S the Right Cylinder?
Choose this 200mm bore cylinder when your application requires up to 15708N of push force at 0.5MPa, stepping up significantly from the 160mm bore which provides 10053N. The adjustable stroke is highly beneficial for machine setup and product changeover, letting you fine-tune the end-of-travel position on the fly. For operations needing true load-holding without live air pressure, this cylinder's adjuster will not suffice; consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock instead.
Because the 650mm stroke creates a long, unsupported rod extension, external guide rails are strongly recommended to prevent excessive side-loading and premature seal wear. When replacing an ISO 15552 cylinder, verify the 200mm bore, 650mm stroke, 100mm adjustment range, PT G3/4 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ200AX650-100S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder generates 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it delivers up to 3204 kgf of push force.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window between 550mm and 650mm, letting you fine-tune the end position without replacing the cylinder.
