About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-10S
The AirTAC SAIJ200X475-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 475 mm nominal travel by up to 10 mm. This yields a precise 465-475 mm usable window, enabling exact end-position tuning at commissioning without swapping the barrel or adding external stops. In the 200 mm bore class, it delivers 15708 N of thrust at 0.5 MPa and up to 3204 kgf at its 1.0 MPa maximum, making it suited to heavy-duty positioning tasks.
This variant features an SUS420J2 stainless steel rod for enhanced durability against moisture and light scoring. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches for position feedback. The PT tapered ports and 50 mm cushion strokes at both ends manage the kinetic energy of this large-bore actuator effectively.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-10S Is Used
Heavy Press Tuning
Dial in the exact 465-475 mm end-stop during machine commissioning to synchronize heavy pressing tools without machining custom spacers.
Product Changeover
Quickly adjust the rear stopper by a few millimeters to accommodate a new product size on an automated assembly line, minimizing downtime.
Large Platen Indexing
Move heavy industrial platens with 15708 N of thrust at 0.5 MPa while relying on the 50 mm cushion strokes to safely absorb the kinetic energy.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-10S the Right Cylinder?
Choose this 200 mm bore actuator when a process requires high force (15708 N at 0.5 MPa) and a 475 mm stroke that needs micro-adjustments to sync with machine tooling or product stops. If an application demands less thrust, stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N, whereas the 200 mm bore is necessary for pressing, lifting, or holding heavy platens. The rear adjuster acts purely as a mechanical stop to set the travel end and relies on the internal air cushion for deceleration; it does not hold the load without live air pressure. For true fail-safe load holding, select the SAIL pneumatic-lock or BSAI clamp-lock series instead.
Because the 475 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide a robust interface, but long unsupported strokes still require an external guide to prevent side-loading damage. When replacing an ISO 15552 cylinder, match the 200 mm bore, 475 mm stroke, 10 mm adjustment, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting the FB, CA, CB, and CR brackets.

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 SAIJ200AX475-10S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the effective travel from the 475 mm nominal stroke down to 465 mm. This provides a 10 mm tuning window for precise end-position setting at commissioning, but it functions as a mechanical stop and does not lock the load without live air pressure.
