About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-100S
The AirTAC SAIJ200X550-100-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. Equipped with a 40mm SUS420J2 stainless steel rod and a PT G3/4 port, it delivers a substantial push force of 15708N at 0.5 MPa. The integrated rear adjuster allows you to dial back the 550mm nominal stroke by up to 100mm, creating a precise 450-550mm usable travel window for exact end-position tuning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during product changeovers. It features an extruded aluminum barrel with sensor grooves on both sides, and the included magnet (-S) supports CMSE reed and DMSE electronic solid-state switches. The rear stopper sets the travel end, but it is not a locking device, so live air is required to hold the load.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-100S Is Used
Heavy Press Tuning
Fine-tune the 450-550mm travel window during heavy press commissioning to achieve exact bottom-dead-center positioning without external stopper blocks.
Product Size Changeover
Quickly adapt automated machinery to different product heights by dialing the rear adjuster, saving time on production line changeovers.
Long-Stroke Positioning
Leverage the 15708N thrust and rigid 40mm SUS420J2 rod for large-scale material handling, using the variable end-stop to dial in the exact retract distance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX550-100S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires massive thrust, offering 15708N push and 15080N pull at 0.5 MPa. If your force requirements are lower, stepping down to a 160mm bore provides 10053N of push force, which may simplify your pneumatic setup. The 100mm adjustment range is ideal for fine-tuning the retract end at commissioning without altering your machine frame. Because the 550mm stroke is substantial, the 40mm rod diameter provides excellent rigidity, but an external guide is still recommended to manage side loads on long unsupported travels.
When replacing an ISO 15552 cylinder, match the 200mm bore, 550mm stroke, 100mm adjustment, PT G3/4 port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. For applications needing true load-holding without live air pressure, consider the AirTAC SAIL or BSAI series instead of relying on the rear stopper.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ200AX550-100S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjusting screw acts as a mechanical stop that allows you to shorten the 550mm nominal stroke by up to 100mm, providing a usable travel window of 450-550mm. It only sets the travel end and does not lock the load without live air.
