About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10S
The AirTAC SAIJ200X45-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust with precision end-position tuning. It generates 15708N of push force and 15080N of pull force at 0.5 MPa, utilizing a robust 40mm piston rod. The integrated -S magnet enables position sensing via CMSE reed or DMSE electronic switches. By turning the rear stopper, you can fine-tune the effective travel window down to 35 mm without swapping out the unit.
This adjustable-stroke model features an SUS420J2 stainless steel rod for enhanced durability against corrosion and side loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Fluid is filtered air, operating between 0.15 and 1.0 MPa, with variable air cushions at both ends to decelerate the heavy 200mm bore payload safely.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10S Is Used
Heavy Press Tuning
Dial in the exact 35-45mm travel end-stop during heavy press commissioning to accommodate material thickness variations without external shims.
Product Changeover
Quickly adjust the rear stopper on automated assembly lines when switching between product variants requiring slightly different stroke endpoints.
Robotic End Effectors
Provides massive 15708N thrust for heavy-duty gripping and forming tasks, with the -S magnet enabling DMSE solid-state sensors to confirm retraction.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX45-10S the Right Cylinder?
Choose this 200mm bore when an application requires extreme force, as it yields 15708N push at 0.5 MPa. If you need less power, stepping down to a 160mm bore provides 10053N, which may better suit medium-heavy tasks. The 10mm adjustment range is ideal for machine setup and product changeover, allowing you to dial in the exact 35-45mm travel end-point without adding external stops. For load-holding without live air pressure, this cylinder is insufficient; the rear adjuster acts only as a travel stop, so consider an AirTAC SAIL or BSAI lock model. This SKU includes a PT tapered port, SUS420J2 rod, and an -S magnet.

- ✓ 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 SAIJ200AX45-10S FAQ
At 0.5 MPa, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum push force of 21991N at 0.7 MPa.
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 45mm nominal stroke by up to 10mm. This creates a usable 35-45mm travel window for fine-tuning end positions without replacing the cylinder.
