About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30
The AirTAC SAIJ200X700-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 700 mm travel by up to 30 mm for a precise 670-700 mm usable window. Built with a SUS420J2 stainless steel rod and PT tapered ports, it delivers immense thrust up to 28274 N at 0.9 MPa, making it suitable for heavy-duty press operations. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback integration.
Because the rear adjuster acts purely as a mechanical stop to set the end-of-travel position, it does not hold the load without live air pressure. For applications requiring true fail-safe load holding, consider the related SAIL pneumatic lock or BSAI clamp-lock series. This model uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30 Is Used
Heavy Press Tuning
Dial in the exact 670-700 mm end position during heavy press commissioning to accommodate varying material thicknesses without external stopper blocks.
Assembly Line Changeover
Quickly adjust the retract stop during product-size changeovers on large-vehicle assembly lines, reducing downtime by keeping the same ISO 15552 footprint.
Variable Stroke Clamping
Set precise clamping travel for oversized components, using the rear screw to tune the stroke window perfectly to the part dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30 the Right Cylinder?
Choose this 200 mm bore unit when a 160 mm bore (providing 18095 N push at 0.9 MPa) is insufficient for your heaviest machinery demands. An adjustable stroke is highly advantageous here for product changeovers, letting you fine-tune the end position without swapping the cylinder or adding external stops. When configuring your ISO 15552 replacement, match the 700 mm stroke, 30 mm adjustment, PT port threads, and the SUS420J2 rod material.
With a 700 mm stroke, the 40 mm diameter rod requires careful alignment to prevent excessive side-loading. Even with the robust rod thread, an external guide is strongly recommended to support the load over this long unsupported travel. Operating speed is capped at 30-500 mm/s for this large bore size.
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 SAIJ200AX700-30 FAQ
At 0.9 MPa operating pressure, this 200 mm bore cylinder provides a push force of 28274 N and a pull force of 15080 N. It reaches a maximum force of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 700 mm down to 670 mm, creating a 670-700 mm adjustable window. This mechanical stop fine-tunes the retract position at commissioning but does not lock or hold the load without continuous air pressure.
