About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100S
The AirTAC SAIJ200X475-100-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 15708N push force at 0.5 MPa. It features a 475mm nominal stroke paired with a 100mm rear adjuster, creating a precise 375-475mm usable travel window for exact end-position tuning. This rear stopper mechanism allows operators to dial in the stroke during commissioning without swapping out the entire cylinder.
Equipped with a SUS420J2 stainless steel rod and PT tapered ports, this unit is built for demanding environments. 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. It utilizes variable air cushions at both ends to manage kinetic energy, though the adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100S Is Used
Heavy Press Tuning
Fine-tune the 375-475mm end-stop during machine commissioning to precisely set the forming depth on large metal pressing equipment without external shims.
Product Changeover
Rapidly adjust the rear stroke stopper to accommodate different pallet sizes on a heavy-duty transfer line, minimizing downtime between production runs.
Large Assembly Positioning
Leverage the 15708N push force to move massive components into place while using the 100mm adjustment window to dial in the exact clamping position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX475-100S the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires up to 3204kgf of maximum thrust and on-the-fly stroke adjustments within a 375-475mm range. If your force requirements are lower, stepping down to a 160mm bore provides 10053N push force at 0.5 MPa, which may reduce air consumption. Because this model features a 475mm stroke, an external guide is strongly recommended to prevent excessive side-loading on the 40mm rod. For load-holding without continuous live air pressure, a standard SAIJ is insufficient; you should explore an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm your requirements for a 200mm bore, 475mm stroke, 100mm adjustment range, PT ports, and the -S magnet option. The available mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting 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 SAIJ200AX475-100S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from the 475mm nominal stroke down to as little as 375mm, giving a 100mm tuning window. It does not lock the load in place without live air pressure; it only sets the travel end-point.
