About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-30
The AirTAC SAIJ200X110-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 110 mm nominal travel by up to 30 mm. This yields a usable 80-110 mm end-position window, perfect for fine-tuning machine setup without adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the adjustable rear stopper simply sets the travel limit—it is not a lock, so the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-30 Is Used
Heavy Press Tuning
Dial in the exact 80-110 mm retraction point on heavy pressing tasks, ensuring precise contact force without swapping out the entire cylinder.
Product Changeover Stops
Adjust the end-stop rapidly during packaging line size changeovers, using the 30 mm trim window to accommodate varying product lengths.
Assembly Station Setup
Fine-tune the retraction end position during initial commissioning of heavy assembly stations, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-30 the Right Cylinder?
Choose this 200 mm bore cylinder when you need extreme force (up to 15708 N push at 0.5 MPa) combined with precise end-stop tuning. If your application requires less thrust, stepping down to a 160 mm bore yields 10053 N push force at 0.5 MPa, which might better suit medium-duty setups. The adjustable stroke is ideal for product changeovers where the exact retraction point varies slightly. Because the stroke is 110 mm, side-load risks are minimal, but always ensure the M36x2 rod thread is properly aligned.
For a direct ISO 15552 replacement match, specify a 200 mm bore, 110 mm stroke, 30 mm adjustment, PT ports, and the SUS420J2 rod. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If you need true load-holding without continuous air pressure, look to the SAIL or BSAI series instead of relying on the rear stopper.

- ✓ 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 SAIJ200AX110-30 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of thrust.
The rear adjuster acts as a mechanical stop that lets you shorten the 110 mm nominal stroke by up to 30 mm, creating a usable travel window of 80 to 110 mm. This allows you to fine-tune the end position at commissioning without changing the cylinder, though it does not lock the load without live air.
