About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10
The AirTAC SAIJ200X800-10 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear mechanical stopper that allows you to dial back the effective stroke by up to 10 mm, creating a precise 790-800 mm travel window for on-the-fly end-position tuning. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles massive loads with ease.
This model features a SUS420J2 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE solid-state switches if position feedback is later required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10 Is Used
Heavy Press Tuning
Dial in the exact 790-800 mm retraction end-stop during heavy press commissioning to accommodate material thickness variations without external shims.
Large Assembly Jigs
Adjust the end-of-stroke position on large-scale assembly fixtures during product changeovers, saving downtime by avoiding complete cylinder swaps.
Long-Stroke Forming
Provide precise mechanical end-positioning for long-stroke forming or bending processes where a 10 mm fine-adjustment window ensures perfect material contact.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-10 the Right Cylinder?
Choose this 200 mm bore cylinder when your process requires up to 15708 N of push force at 0.5 MPa, stepping up from a 160 mm bore that provides 10053 N. The 10 mm rear adjuster is ideal for fine-tuning the retraction end during commissioning or product changeover without swapping the actuator or adding external stops. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider an external rod lock or the AirTAC SAIL lock series.
Because the 800 mm stroke is long and unsupported, the 40 mm rod and M36x2 thread still require an external guide to prevent excessive side-loading and premature wear. This actuator uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 standards.

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 SAIJ200AX800-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 3204 kgf at 1.0 MPa.
A rear external screw stopper lets you shorten the nominal 800 mm stroke by up to 10 mm, creating a 790-800 mm usable travel window. This allows precise end-position tuning during setup without replacing the cylinder.
