About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100
The AirTAC SAIJ200X450-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 450 mm travel back by up to 100 mm. This creates a precise 350-450 mm usable stroke window, letting you dial in the exact end position during commissioning without adding external stopper blocks. Built with a robust 40 mm piston rod, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for moving heavy industrial loads.
This unit is configured with 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 while this specific SKU omits the magnet, the design readily supports AirTAC CMSE reed and DMSE electronic sensors when position feedback is required. The rear adjuster acts purely as a mechanical stop to set the travel end; it does not lock or hold the load without continuous air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100 Is Used
Heavy Press Tuning
Dial in the exact 350-450 mm travel window on a large assembly press during setup, accommodating varying material thicknesses without changing the cylinder.
Pallet Changeover Stops
Adjust the rear stopper to modify the end position for different pallet sizes on a heavy-duty conveyor line, ensuring precise indexing.
Large Fixture Positioning
Fine-tune the end-stop location on automated welding or machining fixtures to compensate for tooling wear over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-100 the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires substantial thrust—up to 15708 N at 0.5 MPa—that exceeds the 10053 N output of the smaller 160 mm bore. The adjustable stroke is highly beneficial for product changeovers on a line, allowing operators to fine-tune the end position quickly rather than physically swapping out a fixed-stroke SAI cylinder. If the load must be held securely in place without live air pressure, note that the SAIJ adjuster is only a travel stop, not a lock; you would need to step up to an SAIL air-released lock or a BSAI clamp-lock cylinder for fail-safe holding.
For an ISO 15552 replacement match, ensure the target unit shares this exact configuration: 200 mm bore, 450 mm stroke, up to 100 mm adjustment range, PT tapered G3/4 ports, and a compatible mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 450 mm stroke creates a long unsupported rod extension, an external guide rail is strongly recommended to prevent excessive side-loading and premature seal wear.

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 SAIJ200AX450-100 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum thrust of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, the nominal 450 mm stroke can be dialed back by up to 100 mm, giving you a usable travel window of 350 to 450 mm to fine-tune the end position at commissioning.
