About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100
The AirTAC SAIJ200X500-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. It provides a 15708N push force at 0.5 MPa and up to 28274N at 0.9 MPa. By integrating a 100mm adjustment screw, this unit creates a precise 400-500mm usable travel window, allowing operators to dial in the retract end-position without swapping out the entire actuator.
Built with an extruded aluminum barrel and an SUS420J2 stainless steel rod, it handles demanding environments while maintaining a standard 30-500mm/s operating speed. The PT tapered port threads ensure a high-integrity pneumatic connection. This adjustable configuration is ideal for heavy product changeovers, giving you the flexibility to trim the stroke on the fly rather than relying on fixed stops or external mechanical hard stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100 Is Used
Heavy Machinery Positioning
Provides the immense force needed to shift heavy structural components, using the 100mm adjuster to fine-tune the resting position for different assembly jig lengths.
Product Line Changeover
Enables rapid line adjustments for varying product sizes, allowing operators to trim the 500mm stroke back to 400mm without disassembling the pneumatic setup.
Large Press Feeding
Delivers raw push power up to 28274N at 0.9 MPa for feeding thick materials into a press, while the rear stopper guarantees consistent retraction depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-100 the Right Cylinder?
Selecting this 200mm bore actuator is necessary when your application requires extreme force that smaller bores cannot provide, such as shifting from a 160mm bore that yields 10053N at 0.5 MPa. The 100mm adjustment window is the primary draw here, enabling fine-tuning of the end-of-stroke position during commissioning or product size changes. Because the nominal 500mm stroke is substantial, an external guide is strongly recommended to prevent excessive side-loading on the 40mm rod, preserving seal integrity over millions of cycles.
When matching this to an ISO 15552 footprint, ensure your parameters align: a 200mm bore, 500mm stroke, 100mm adjustment, PT G3/4 ports, and the SUS420J2 rod material. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ200AX500-100 FAQ
At 0.5 MPa it provides a push force of 15708N and a pull force of 15080N. At 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw allows you to shorten the nominal 500mm stroke by up to 100mm, creating a usable travel window of 400-500mm. It functions as a mechanical stop to set the retract position and is not a lock.
