About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30S
The AirTAC SAIJ200X700-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive 28274N of push force at 0.9 MPa. A built-in magnet (-S) enables position monitoring with AirTAC CMSE reed or DMSE electronic sensors fitted into the dual-side barrel grooves. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability against moisture, while the PT tapered ports ensure a tight pneumatic connection.
By turning the external rear stopper screw, you can fine-tune the effective travel window down from a 700 mm nominal stroke to a 670 mm minimum. This allows precise end-position calibration during commissioning or product changeover without adding external stops. Note that the adjuster acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30S Is Used
Heavy Press Calibration
Dial in the exact 670 to 700 mm end-position for large stamping or pressing operations without swapping out the entire cylinder.
Product Changeover
Quickly adapt the retract end-stop on automated assembly lines when transitioning to components of different sizes.
Industrial Automation
Leverage the 28274N thrust and PT tapered ports for robust, high-force actuation in demanding manufacturing environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-30S the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (offering 18095N push at 0.9 MPa) is insufficient for your heavy-duty application. The adjustable stroke is ideal for machinery requiring variable end-stops on the fly, unlike a fixed-stroke SAI cylinder. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 700 mm stroke is substantial, the M36x2 rod thread and 40 mm rod diameter carry high side-load capacity, but an external guide is still recommended to prevent binding over long unsupported travel.
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 SAIJ200AX700-30S FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder generates a push force of 28274N and a pull force of 15080N.
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 30 mm, providing a usable travel window of 670 to 700 mm for precise end-position tuning.
