About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-10
The AirTAC SAIJ200X650-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, featuring a 200mm bore and a 650mm stroke. A rear mechanical adjuster allows you to trim the effective travel by up to 10mm, creating a precise 640-650mm usable window for fine-tuning the retract end position during commissioning. Operating at 0.5 MPa, it generates 15708N of push force and 15080N of pull force, while the SUS420J2 stainless steel rod provides robust corrosion resistance for demanding environments.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when product sizes change on a line. It features PT tapered port threads and dual air cushions at both ends to manage deceleration of the massive 3204 kgf maximum load. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-10 Is Used
Heavy Press Tuning
Dial in the exact 640-650mm retract position during machine setup to ensure massive 15708N pressing forces are applied consistently without re-machining hard stops.
Large Mold Changeover
Quickly adapt the end-stop position by up to 10mm when swapping large molds on a production line, saving downtime compared to physically replacing the cylinder.
Heavy Conveyor End-Stop
Use the rear adjuster to fine-tune where large pallets or heavy assemblies halt on a 650mm stroke conveyor, compensating for mechanical wear over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-10 the Right Cylinder?
Select this 200mm bore model when your application requires extreme thrust—stepping down to a 160mm bore drops the 0.5 MPa push force to 10053N. The 10mm adjustment range on this SAIJ200X650-10 is ideal for micro-adjusting the end-of-stroke position without changing the cylinder. Because the 650mm stroke is substantial and the rod diameter is 40mm, an external guide is strongly recommended to prevent excessive side loads from damaging the rod seals. For position feedback, you would normally specify the -S magnet option to use CMSE reed or DMSE electronic sensors, but this specific configuration omits the magnet.
When replacing an ISO 15552 cylinder, match the 200mm bore, 650mm stroke, 10mm adjustment, PT G3/4 ports, and the available mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This profile cylinder uses an extruded aluminum barrel with sensor grooves on both sides and omits 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 SAIJ200AX650-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to shorten the 650mm nominal stroke by up to 10mm, giving a usable travel window of 640-650mm. This stopper sets the end position but does not lock or hold the load without continuous air pressure.
