About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30
The AirTAC SAIJ200X1000-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a rear mechanical adjuster that permits up to 30 mm of stroke reduction. This creates a precise 970-1000 mm usable travel window, enabling exact end-position tuning at commissioning without swapping out the cylinder or adding external stops. Delivering 15708 N of push force at 0.5 MPa, it handles massive loads with ease.
This unit incorporates a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and operates at 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE solid-state switches. The rear adjuster acts strictly as a travel stop to set deceleration limits, meaning it will not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30 Is Used
Heavy Press Positioning
Dial in the 970-1000 mm travel window on large stamping or press lines to accommodate varying material thicknesses without re-engineering the entire cylinder station.
Product Line Changeover
Quickly fine-tune the retract end-position by up to 30 mm during automated packaging size transitions, ensuring precise stops without adding external mechanical spacers.
Large Assembly Tuning
Leverage the 15708 N push force at 0.5 MPa to move heavy pallets or assemblies, using the rear adjuster to set exact deceleration points during initial commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-30 the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application requires the maximum standard thrust capacity, pushing 15708 N at 0.5 MPa or 21991 N at 0.7 MPa. If your force requirements are lower, stepping down to a 160 mm bore saves space and yields 10053 N at 0.5 MPa. The adjustable stroke is specifically chosen for machine setups needing variable end-stops during product changeovers rather than relying on a fixed-stroke SAI cylinder.
Because the stroke is 1000 mm, the 40 mm diameter rod and M36x2 thread will experience significant side-load leverage if the load is unsupported; an external guide mechanism is mandatory to prevent rod binding. For an exact ISO 15552 replacement match, verify the 1000 mm stroke, 30 mm adjustment range, PT tapered G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this SAIJ variant omits the FB, CA, CB, and CR mounts.

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 SAIJ200AX1000-30 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 1000 mm stroke by up to 30 mm, providing a usable travel window of 970-1000 mm. It sets the end-position and deceleration limit but does not lock or hold the load without live air pressure.
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
