About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-100S
The AirTAC SAIJ200X375-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear mechanical adjuster. With a 375mm nominal stroke and a 100mm adjustment range, the usable travel window can be dialed back to anywhere between 275mm and 375mm. This allows operators to fine-tune end positions at commissioning without swapping out the physical cylinder or adding external stops.
This SKU features a carbon steel piston rod and PT (tapered) port threads. It includes a magnet (-S) for position sensing, functioning seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches housed in the dual-side sensor grooves. The rear adjuster acts purely as a travel stop to set deceleration limits, meaning it will not hold a load safely without live air pressure. For load-holding requirements, an external rod lock or related SAIL and BSAI series cylinders should be evaluated.

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 SAIJ200X375-100S Is Used
Heavy Press Changeovers
Adjust the 275-375mm travel window on the fly to accommodate different material thicknesses in heavy pressing and forming operations without changing tooling.
Variable Pallet Stops
Dial in the exact end-stop position for varying pallet sizes on a high-capacity conveyor line, using the rear screw to set precise deceleration limits.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-100S the Right Cylinder?
The 100mm adjustment window is ideal for accommodating varying material thicknesses or package sizes on the fly. Because the 375mm stroke is substantial, the 40mm rod diameter and M36x2 thread provide robust support, but an external guide is strongly recommended to prevent side-loading damage over this long unsupported travel.
When matching this ISO 15552 dimensionally interchangeable cylinder for replacement, verify the 200mm bore, 375mm stroke, 100mm adjuster, PT port threads, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ200X375-100S FAQ
At its maximum rated pressure of 1.0MPa, it can deliver up to 3204 kgf.
The rear mechanical adjuster allows you to shorten the 375mm nominal stroke by up to 100mm, creating a usable travel window of 275mm to 375mm. This adjuster functions as an end-stop to tune the travel length and cannot hold the load without continuous air pressure.
