About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10
The AirTAC SAIJ200X135-10 is a double-acting, single-rod ISO 15552 profile cylinder engineered for high-force applications requiring precise end-position tuning. Equipped with a robust 40mm piston rod and a rear-mounted stroke adjuster, it provides a usable travel window of 125 to 135mm. This allows operators to dial in the exact retraction point during commissioning without swapping out the entire unit or adding external stops. Delivering 15708N of push force at 0.5 MPa, it handles massive loads with ease.
This heavy-duty actuator features a SUS420J2 stainless steel rod for superior corrosion resistance and uses PT tapered port threads (G3/4) for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches when a magnet is specified separately. It operates at speeds between 30 and 500mm/s and relies on adjustable air cushions at both ends to decelerate the heavy 200mm bore payload smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10 Is Used
Heavy Press Calibration
Fine-tune the 125-135mm stroke window on heavy presses to accommodate different material thicknesses without changing the cylinder setup.
Product Line Changeover
Adjust the rear stopper during product size changeovers on high-force assembly lines, saving time by avoiding physical hardware swaps.
End-Stop Tuning
Dial in the exact retraction end-position during machine commissioning to prevent mechanical crashes and ensure precise heavy-load placement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX135-10 the Right Cylinder?
Selecting the SAIJ200X135-10 is optimal when an application demands extreme thrust alongside a variable end-stop. If you need to step the bore down for a lighter load, the 160mm bore provides 10053N of push force at 0.5 MPa, which might suffice for mid-tier machinery. However, for loads approaching 15708N, this 200mm bore is required. The 10mm adjustment window is perfect for final mechanical calibration during machine setup or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot match.
When integrating this model, remember that the rear adjuster functions strictly as a travel stop, not a locking device; it cannot hold a load without continuous live air pressure. For applications requiring true load-holding in the event of air loss, consider the SAIL or BSAI series instead. Because the 135mm stroke is relatively short for this large bore, side-load stress is minimized, but external guides are still recommended for heavy off-center loads. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 hardware, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200AX135-10 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 28274N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 135mm stroke by up to 10mm, creating a 125-135mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
