About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-100
The AirTAC SAIJ200X475-100 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications. A rear mechanical adjuster allows you to shorten the effective travel, providing a usable stroke window of 375 to 475 mm for precise end-position tuning during machine commissioning.
This model utilizes PT tapered port threads (G3/4) and operates at speeds of 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The rear stopper acts strictly as a travel end-stop for deceleration and positioning, not a load-holding lock, meaning live air pressure is required to maintain position.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-100 Is Used
Heavy Press Tuning
Dial in the exact 375 to 475 mm travel window during heavy press commissioning to accommodate different material thicknesses without external stopper blocks.
Automated Line Changeover
Adjust the rear stopper up to 100 mm during product size changeovers on large automated lines, saving the downtime of physically replacing a 200 mm bore cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-100 the Right Cylinder?
Choose this 200 mm bore when your application requires extreme force, stepping up from the 160 mm bore which provides 10053 N at 0.5 MPa. The 100 mm adjustment range is ideal for machinery processing varying product sizes, allowing you to dial back the 475 mm nominal stroke without swapping hardware or adding external stops. For fixed-travel setups requiring no end-tuning, the standard SAI cylinder is a simpler alternative.
Because this 475 mm stroke exceeds 300 mm, the heavy 40 mm rod and M36x2 thread provide excellent structural rigidity, but an external guide is still recommended to prevent side-load damage on long unsupported extensions. If your process requires the load to be held mechanically without continuous air pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants, as the SAIJ adjuster cannot hold loads unpressurized. This cylinder is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ200X475-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 100 mm, creating a usable travel window of 375 to 475 mm. This stopper sets the travel end for positioning but does not lock or hold the load without live air pressure.
