About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75S
The AirTAC SAIJ200X75-75-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a massive 15708N of thrust at 0.5 MPa. A rear mechanical stopper allows you to dial back the 75mm nominal stroke by up to 75mm, creating a 0-75mm usable travel window for exact positioning during product changeovers. This eliminates the need to physically swap cylinders or bolt on external stops to fine-tune the retract end.
Built for harsh environments, this variant features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and because this SKU includes a magnet (-S), it supports direct mounting of AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection. Fluid supply arrives via PT tapered G3/4 ports.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75S Is Used
Heavy Pressing Operations
Delivers 15708N of thrust at 0.5 MPa for assembling heavy components, with the 75mm travel window allowing precise depth control during setup.
Forming and Bending
The adjustable 0-75mm stroke accommodates varying material thicknesses on a single machine without changing out the entire actuator.
Automated Changeover Stops
Quickly tune the retract end-position during product line changeovers using the rear stopper, avoiding the downtime of adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-75S the Right Cylinder?
Selecting this 200mm bore model provides up to 3204kgf at 1.0 MPa, making it ideal for high-force pressing and heavy load manipulation. If your application requires less force, stepping down to a 160mm bore yields 10053N at 0.5 MPa, which might better suit medium-duty handling while saving envelope space.
The rear adjuster screw on this SAIJ cylinder acts strictly as a travel stop to set deceleration and end-position; it does not hold the load without live air pressure. For applications requiring true fail-safe load holding, consider the AirTAC SAIL pneumatic lock series or an external rod lock. When replacing an ISO 15552 cylinder, match the 200mm bore, 75mm stroke, 75mm adjustment range, PT G3/4 port, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2).

- ✓ Side load — consider a guided cylinder
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 SAIJ200AX75-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel from 75mm down to 0mm. It sets the end position and deceleration point, but it is not a lock and will not hold a load without continuous air pressure.
At 0.5 MPa operating pressure, it provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 3204kgf.
