About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-10S
The AirTAC SAIJ200X750-10-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 740-750 mm usable travel window, allowing you to dial back the 750 mm nominal stroke by up to 10 mm during commissioning without adding external stops. Built with a robust 40 mm SUS420J2 stainless steel rod and M36x2 thread, it handles massive loads, delivering 21991 N of push force at 0.7 MPa.
This large-bore pneumatic actuator uses PT tapered ports (G3/4) for a tight, leak-free connection. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet enables precise end-of-stroke detection with AirTAC CMSE reed or DMSE solid-state switches. Operating at speeds of 30-500 mm/s, it relies on 50 mm variable air cushions at both ends to decelerate the heavy piston smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-10S Is Used
Heavy Press End-Position Tuning
Dial in the exact 740-750 mm retract stop during heavy press commissioning to accommodate varying material thicknesses without swapping actuators.
Large Product Changeover Stops
Adjust the rear stopper by up to 10 mm on the fly when a packaging line switches between large pallet sizes, ensuring precise positioning.
Heavy-Duty Assembly Forming
Generate up to 28274 N of push force at 0.9 MPa for forming and joining heavy assemblies, using the 50 mm cushions to safely decelerate the massive 200 mm piston.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-10S the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires extreme thrust—up to 28274 N at 0.9 MPa—that exceeds the 18095 N push force of the neighbouring 160 mm bore. The 10 mm adjustable range is ideal for fine-tuning the retract end position during machine setup or product changeover, preventing the need to physically swap cylinders for slight dimensional variations. For any fixed-stroke requirements without end-position tuning, the standard AirTAC SAI series is the alternative.
Because the 750 mm stroke creates a long unsupported rod extension, an external guide rail is strongly recommended to prevent side-load damage to the rod seals and barrel. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air pressure. For true fail-safe load holding, select the SAIL (air-released lock) or BSAI (clamp-lock) cylinder series instead. This SAIJ model supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ200AX750-10S 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 0.9 MPa, the push force reaches 28274 N.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from 750 mm down to 740 mm. This allows precise end-position tuning at commissioning without changing the cylinder or adding external stops.
