About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40
The AirTAC SAIJ200X500-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a rear screw mechanism that allows you to trim the effective stroke. This specific SKU provides a 460-500 mm usable travel window, enabling precise end-position tuning during commissioning without swapping out the entire unit. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
Built with a robust 40 mm piston rod and a PT tapered port, this model handles extreme loads effectively. The rod utilizes SUS420J2 stainless steel (code A) for superior corrosion resistance, while the extruded aluminum barrel incorporates sensor grooves on both sides. The rear stopper functions strictly as a travel end-deceleration device, not a lock, meaning live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40 Is Used
Heavy Press Tuning
Fine-tune the 460-500 mm stroke end-position on heavy presses during setup, avoiding the need to physically swap large cylinders for different material thicknesses.
Pallet Changeover
Adjust the rear stopper on the fly to accommodate varying pallet sizes on a high-thrust conveyor line without bolting on external mechanical stops.
Large Assembly Jigs
Dial in the exact retraction point for heavy assembly jigs, utilizing the 15708 N push force to move substantial components safely and accurately.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-40 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when your application requires up to 15708 N of push force at 0.5 MPa, stepping up from a 160 mm bore that yields 10053 N. The adjustable 460-500 mm window is ideal for machinery requiring frequent product-size changeovers, allowing operators to dial in the exact end-stop without adding external spacers. Because the nominal stroke is 500 mm, an external guide is recommended to manage side-load stresses on the long, unsupported rod.
For a direct ISO 15552 replacement match, ensure you specify the 200 mm bore, 500 mm stroke, -40 mm adjustment, PT port threads, and the SUS420J2 rod material. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. If your process demands true load-holding without continuous air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL or BSAI locking cylinder instead.

- ✓ 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 SAIJ200AX500-40 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 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.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 500 mm nominal stroke by up to 40 mm, creating a 460-500 mm usable travel window. Note that this adjuster only sets the travel end and does not lock the load without live air pressure.
