About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-40S
The AirTAC SAIJ200X200-40-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a substantial 15708N push force at 0.5MPa. It features a 200mm nominal stroke paired with a rear adjusting screw that provides a usable travel window of 160-200mm, allowing you to dial in the exact retract end-position without swapping out the unit. The integrated -S magnet enables position detection with AirTAC CMSE reed or DMSE electronic solid-state sensors.
Built with an extruded aluminum barrel housing dual sensor grooves, this model utilizes a robust 40mm rod with an M36x2 thread and a PT tapered port connection. The rod itself is crafted from SUS420J2 stainless steel (code A) for superior corrosion resistance. It includes variable air cushions at both ends to manage kinetic energy, and the rear stopper acts purely as a travel limit rather than a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-40S Is Used
Heavy Press Tuning
Fine-tune the 160-200mm travel window during commissioning to set precise pressing depths on heavy industrial assemblies without changing the cylinder.
Product Changeover
Quickly adjust the retract end-stop on a production line when switching between part sizes, leveraging the 40mm adjustment range for rapid setup.
Large Material Handling
Move substantial loads using the 15708N push force at 0.5MPa, relying on the robust 40mm SUS420J2 stainless steel rod to withstand harsh environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX200-40S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires extreme thrust, such as 15708N push or 15080N pull at 0.5MPa. If your force requirements are lower, stepping down to a 160mm bore yields 10053N of push force, significantly reducing air consumption and physical footprint. The adjustable 160-200mm travel window is ideal for machine setups requiring fine end-position tuning during commissioning or product changeovers, eliminating the need to bolt on external stops. For operations needing secure load holding without live air pressure, a standard SAIJ is insufficient as the adjuster is only a stop; consider an AirTAC SAIL or BSAI locking cylinder instead.
When matching this for an ISO 15552 replacement, verify the 200mm stroke, 40mm adjustment range, PT G3/4 port, and the -S magnet requirement. Because the stroke is 200mm, ensure adequate external guiding to prevent excessive side-loading on the rod. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ200AX200-40S FAQ
At 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7MPa, the push force increases to 21991N.
The rear adjuster screw allows you to trim the effective stroke by up to 40mm, creating a usable travel window of 160-200mm. This stopper only limits the travel end and does not hold the load without continuous air pressure.
