About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-100
The AirTAC SAIJ200X375-100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear-mounted adjusting screw that allows you to trim the effective travel, providing a 275-375 mm usable stroke window from the 375 mm nominal length.
This model uses a carbon steel piston rod with an M36x2 thread and a G3/4 port. The extruded aluminum barrel incorporates sensor grooves on both sides for CMSE reed or DMSE electronic switches, though this SKU is specified without a magnet. The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping components, and the variable air cushions at both ends manage deceleration.

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 SAIJ200X375-100 Is Used
Heavy Press Tuning
Dial in the exact 275-375 mm travel window during heavy press commissioning to accommodate varying material thicknesses without machining external stops.
Large Mold Changeover
Adjust the rear stopper screw quickly during large mold or fixture changeovers on a 200 mm bore line, saving downtime compared to swapping cylinders.
Heavy Positioning Stops
Set precise retract end-positions for heavy material feeding systems, using the 100 mm adjustment range to fine-tune the resting location of large loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-100 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires immense thrust combined with on-the-fly end-position tuning, such as pressing or heavy mold positioning. Choosing the SAIJ adjustable format over a fixed-stroke SAI cylinder prevents the need to machine external stopper blocks during product changeovers.
Because the stroke is 375 mm, the M36x2 rod and heavy load require an external guide to prevent side-load damage to the seals. The rear adjuster is a travel stop, not a locking device; it cannot hold the load without continuous air pressure. For dead-load holding, use an external pilot-operated check valve or explore the BSAI clamp-lock series. This unit is dimensionally interchangeable per ISO 15552, uses a PT tapered port, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

- ✓ 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 SAIJ200X375-100 FAQ
At the maximum rated pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 375 mm nominal stroke by up to 100 mm, creating a 275-375 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
