About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-10
The AirTAC SAIJ200X50-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. It features a robust 200mm bore generating 15708N of push force at 0.5MPa and a 50mm nominal stroke. The integrated rear adjusting screw provides a 10mm trim range, creating a highly customizable 40-50mm usable travel window. This allows operators to dial in the exact retract distance during commissioning without relying on external stops.
Built with a SUS420J2 stainless steel rod and PT tapered port threads, this unit is tailored for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, it operates without electronic position feedback. The rear adjuster functions strictly as a mechanical stop to set the travel end, working alongside the standard 50mm air cushions to decelerate the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-10 Is Used
Heavy Press End-Tuning
Fine-tunes the final 40-50mm travel window on a high-force press, ensuring exact material contact depth without adding external mechanical spacers.
Machine Changeover Setup
Allows operators to quickly dial back the retract position by up to 10mm during product size changes, minimizing downtime on heavy machinery.
Short-Stroke Clamping
Delivers massive 15708N clamping force in a compact 50mm stroke, with the adjuster serving as a hard mechanical stop for precise positioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX50-10 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application demands substantial thrust, such as moving 15708N at 0.5MPa, within a very short 40-50mm adjustable window. If you need less force, stepping down to a 160mm bore reduces the push thrust to 10053N while maintaining a similar short-stroke footprint. Conversely, if your machine requires longer travel, you can move to a standard 200mm stroke, though you would lose the fine-tuning benefit of this specific 10mm adjuster.
When replacing an ISO 15552 cylinder, match the 200mm bore, 50mm stroke, PT port threads, and SUS420J2 rod material. Remember that the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets. Because the stroke is under 300mm, side-load concerns are minimal, but always ensure the load is guided externally. Note that the rear adjuster is a stop, not a lock; for fail-safe load holding without live air pressure, specify an AirTAC SAIL or BSAI 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 SAIJ200AX50-10 FAQ
