About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-100
The AirTAC SAIJ200X900-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion control. It delivers a robust 15708N push force at 0.5 MPa and 21991N at 0.7 MPa. A rear mechanical stopper allows you to dial back the effective travel, providing an 800-900mm usable stroke window for precise end-position tuning during commissioning. The piston rod is constructed from SUS420J2 stainless steel for enhanced durability against lateral stress.
This adjustable-stroke design eliminates the need to swap out the entire barrel or bolt on external stops when adapting to product changeovers. It features a G3/4 PT tapered port and operates at speeds of 30-500mm/s. The extruded aluminum barrel includes sensor grooves on both sides, ready for DMSE solid-state or CMSE reed switches if a magnet is specified later. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-100 Is Used
Heavy Press Tuning
Fine-tune the 800-900mm travel window on a large press to accommodate varying material thicknesses without adding external mechanical stops.
Assembly Line Changeover
Adjust the retract end-position rapidly during product size changeovers on a 200mm bore assembly station pushing up to 21991N.
Long-Stroke Positioning
Utilize the heavy 15708N push force and 100mm adjustment window to set exact ejection distances on long-stroke material handling equipment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX900-100 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application demands up to 3204kgf of maximum thrust at 1.0 MPa, stepping up significantly from a 160mm bore that yields 10053N at 0.5 MPa. The 100mm adjustment range is ideal for machinery requiring variable end-stops or fine-tuning over a long 900mm travel distance. Because this cylinder features a 900mm stroke, an external guide is strongly recommended to prevent excessive side-load wear on the rod and seals.
For ISO 15552 dimensional interchangeability, match the 200mm bore, 900mm stroke, PT G3/4 port, and the specified SUS420J2 rod material. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For fail-safe load holding without continuous air supply, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder series instead.

- ✓ 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 SAIJ200AX900-100 FAQ
It features a rear adjusting screw that acts as a mechanical stopper, allowing you to trim the effective travel back by up to 100mm. This creates a usable stroke window of 800-900mm, letting you fine-tune the end position during setup without replacing the cylinder.
At a 0.5 MPa operating pressure, this 200mm bore double-acting cylinder provides a push force of 15708N and a pull force of 15080N. At 0.7 MPa, the push force increases to 21991N.
