About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40S
The AirTAC SAIJ200X700-40-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. It features a substantial 200mm bore generating 15708N of push force at 0.5MPa and a 700mm nominal stroke. Equipped with a rear adjusting screw, this model allows you to dial back the effective travel by up to 40mm, creating a precise 660-700mm usable stroke window. This adjustability eliminates the need to swap cylinders or bolt on external stops during machine commissioning or product changeovers.
Built with a SUS420J2 stainless steel piston rod (material code A), it provides excellent resistance to wear and corrosion in demanding environments. The extruded aluminum barrel includes sensor grooves on both sides, and because this is a -S variant, it contains a magnet for use with AirTAC CMSE reed and DMSE electronic solid-state sensors. Operating at speeds of 30-500mm/s, this profile cylinder uses PT tapered G3/4 ports and relies on adjustable air cushions at both ends to decelerate the massive 3204kgf maximum load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40S Is Used
Heavy Press Tuning
Dial in the exact 660-700mm retract position during heavy press commissioning without machining new spacers or swapping the cylinder.
Product Size Changeover
Adjust the rear stopper by up to 40mm to accommodate varying product lengths on a high-thrust conveyor line during rapid format changeovers.
Large Assembly Jigs
Leverage the 15708N push force to seat large components while using the rear travel stop to perfectly set the final assembly depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40S the Right Cylinder?
Selecting this 200mm bore model makes sense when your process demands extreme thrust—up to 15708N push and 15080N pull at 0.5MPa—and the ability to fine-tune the retract end-stop on the fly. If your application requires less force, stepping down to a 160mm bore yields 10053N push at 0.5MPa, which might save space and air consumption. Conversely, if you need to hold the load securely without live air pressure, remember that this SAIJ rear adjuster acts only as a travel stop, not a lock; you would need to look at the SAIL (air-released lock) or BSAI (clamp-lock) series instead.
Because the 700mm stroke is substantial, the 40mm diameter rod and M36x2 thread provide a robust interface, but long unsupported strokes still require an external guide to prevent side-loading damage. This cylinder is dimensionally interchangeable per ISO 15552 mounting interfaces and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). When replacing an ISO 15552 cylinder, verify the 200mm bore, 700mm stroke, 40mm adjustment, PT G3/4 port, and the -S magnet requirement.

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 SAIJ200AX700-40S FAQ
At 0.5MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum operating pressure of 1.0MPa, it can deliver up to 3204kgf of push force.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 700mm nominal stroke by up to 40mm, resulting in a usable travel window of 660-700mm. This stopper only sets the end position and does not hold the load without live air pressure.
