About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10
The AirTAC SAIJ200X80-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 80mm travel by up to 10mm for an effective 70-80mm usable window. It delivers massive thrust, generating 15708N of push force and 15080N of pull force at a 0.5MPa operating pressure. Built with an extruded aluminum barrel featuring sensor grooves on both sides, this unit is dimensionally interchangeable per ISO 15552 standards without being a tie-rod design.
This specific SKU features an SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The 40mm rod and M36x2 thread provide exceptional rigidity, though long unsupported strokes still require an external guide. The rear adjuster acts purely as a mechanical stop for end-position tuning and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10 Is Used
Heavy Press Tuning
Dial in the exact 70-80mm retract stop on heavy press operations to accommodate varying material thicknesses without mechanical rebuilds.
Assembly Line Changeover
Quickly adjust the end-position during product size changeovers on the factory floor, saving downtime by avoiding cylinder swaps.
Large Fixture Setup
Fine-tune the end-stop on large welding or clamping fixtures during initial commissioning to achieve perfect positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX80-10 the Right Cylinder?
Choose this massive 200mm bore when you need extreme force that smaller neighbors cannot provide, such as moving heavy assemblies; stepping down to a 160mm bore drops your 0.5MPa push force to 10053N. The 10mm adjustable window is ideal for fine-tuning the retract end during machine setup or product changeover without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, this cylinder's adjuster is insufficient; you should instead look at the SAIL or BSAI series. When replacing an ISO 15552 cylinder, match the 200mm bore, 80mm stroke, 10mm adjustment, PT G3/4 port, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ200AX80-10 FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 80mm stroke by up to 10mm, creating a usable travel window of 70-80mm. This mechanical stop fine-tunes the end position but does not lock or hold the load without live air pressure.
