About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-40S
The AirTAC SAIJ200X195-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 195 mm travel by up to 40 mm. This yields a highly versatile usable travel window of 155 to 195 mm, letting you fine-tune the retract end position during commissioning without swapping out the barrel or adding external mechanical stops. It delivers immense thrust, pushing with 15708 N and pulling with 15080 N at a 0.5 MPa operating pressure.
Built for demanding environments, this unit uses a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback. Variable air cushions at both ends manage deceleration across its 30-500 mm/s speed range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-40S Is Used
Heavy Press Tuning
Dial in the exact 155-195 mm end position for high-force pressing or forming operations without machining custom spacers.
Product Changeover
Quickly adjust the retract stop to accommodate different material thicknesses or product sizes on a high-capacity production line.
Assembly Calibration
Fine-tune the end-of-stroke position during machine commissioning to perfectly align heavy 3204 kgf tooling packages.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX195-40S the Right Cylinder?
Choose this 200 mm bore when your application requires maximum force, generating up to 3204 kgf at 1.0 MPa. If your setup only needs the 0.5 MPa thrust of a 160 mm bore (10053 N push), stepping down reduces physical size and air consumption. You select the SAIJ adjustable-stroke variant over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product size changeovers or precise end-position tuning at setup.
For stroke lengths of 300 mm or more, the large 40 mm rod and M36x2 thread provide excellent rigidity, but an external guide is still recommended to prevent excessive side-loading on the piston. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold a load without live air pressure. For fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses the reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ 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 SAIJ200AX195-40S FAQ
The rear adjuster screw acts as a mechanical stop that can shorten the effective stroke by up to 40 mm. This provides a usable travel window of 155 to 195 mm, allowing you to trim the retract position without replacing the cylinder.
At a 0.5 MPa operating pressure, it provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, the push force increases to 28274 N.
