About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-30S
The AirTAC SAIJ200X650-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 620 to 650 mm usable travel window, allowing you to dial back the nominal 650 mm stroke by up to 30 mm during commissioning. This bore size delivers massive thrust, pushing 21991 N and pulling 15080 N at 0.7 MPa, making it suited for heavy-duty industrial positioning.
This unit includes a magnet for position sensing and uses SUS420J2 stainless steel for the piston rod. It runs at a controlled 30-500 mm/s speed range and features variable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE solid-state switches. Ports are PT tapered thread type.
The rear stopper mechanism sets the retract end position without requiring external stops or cylinder swaps. However, this adjuster acts only as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air supply, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-30S Is Used
Heavy Press Changeover
Dial in the exact 620-650 mm end-stop position during heavy press product changeovers without swapping out the entire cylinder.
Industrial Machine Setup
Fine-tune the retract position at machine commissioning to perfect material seating, using the rear adjuster instead of adding external mechanical stops.
Large Material Positioning
Position heavy materials with up to 21991 N of thrust at 0.7 MPa while relying on the adjuster to set precise travel limits for varying product sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX650-30S the Right Cylinder?
Choose this 200 mm bore cylinder when your application requires extreme force, as it generates 21991 N of push force at 0.7 MPa. If you need slightly less thrust, stepping down to a 160 mm bore yields 14074 N at the same pressure, but the 200 mm bore is necessary for the highest load demands. The adjustable stroke is ideal for machine setups requiring variable end stops or product-size changeovers on a line, offering a 620-650 mm travel window.
Because the 650 mm stroke is substantial, the 40 mm diameter rod and M36x2 thread provide robust support, but long unsupported strokes still need an external guide to prevent excessive side-loading and premature wear. This SAIJ model uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. To match this cylinder as an ISO 15552 replacement, specify: 200 mm bore, 650 mm stroke, 30 mm adjustment, PT G3/4 port, the required mounting bracket, and the -S magnet option.

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 SAIJ200AX650-30S FAQ
At 0.7 MPa operating pressure, this 200 mm bore cylinder provides 21991 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke by up to 30 mm, creating a 620-650 mm usable travel window. It sets the end position but does not lock or hold the load without live air pressure.
