About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-30S
The AirTAC SAIJ200X450-30-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a substantial push force of 15708 N at 0.5 MPa. It features a rear-mounted stroke adjuster that allows you to fine-tune the effective travel window down from a 450 mm nominal stroke to a 420 mm minimum, providing a 30 mm variable end-stop range without external modifications. This specific SKU includes a SUS420J2 stainless steel rod for superior corrosion resistance and a magnetic piston for position sensing.
Equipped with PT tapered port threads (G3/4), this 200 mm bore profile cylinder utilizes variable air cushions at both ends to manage high kinetic energy deceleration. The rear adjuster functions strictly as a travel stop to set the retract position and cannot hold a load without continuous live air pressure. For applications requiring true fail-safe load holding, the related SAIL or BSAI clamp-lock series should be specified instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-30S Is Used
Heavy Press Changeover
Dial in the exact 420-450 mm retract stop during product size changeovers on a heavy press line without adding external mechanical stops.
Large Mold Positioning
Fine-tune the end-position of large molding assemblies at commissioning, using the 30 mm adjustment window to perfectly seat heavy tooling.
Pallet Stopper Tuning
Adjust the variable end-stop on a heavy-duty pallet handling line to compensate for minor mechanical drift over time while maintaining 15708 N of force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-30S the Right Cylinder?
Selecting the SAIJ200X450-30-S is ideal when a machine setup requires exact end-position tuning during commissioning or frequent product-size changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. If your application demands slightly less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, whereas this 200 mm bore maximizes thrust up to 15708 N at the same pressure. Because the 450 mm stroke is substantial, an external guide rail is highly recommended to prevent excessive side-loading on the 40 mm diameter rod and its M36x2 thread.
When matching this ISO 15552 cylinder for a direct replacement, verify the 200 mm bore, 450 mm stroke, 30 mm adjustment code, PT G3/4 port threads, and the -S magnet option for compatibility with AirTAC CMSE reed and DMSE solid-state sensors. The available mounting interface set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

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 SAIJ200AX450-30S FAQ
At 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 of push force.
The rear adjuster acts as a mechanical stop that allows you to shorten the 450 mm nominal stroke by up to 30 mm, creating a usable travel window of 420-450 mm. It only sets the end position and does not lock the load without live air pressure.
