About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-100
The AirTAC SAIJ200X425-100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty operations. It features a rear stroke adjuster that allows you to fine-tune the travel window down from the 425mm nominal stroke, providing a usable range of 325-425mm without needing external stops.
This extruded aluminum barrel design incorporates variable air cushions at both ends to manage the high kinetic energy of a 425mm stroke. The rear adjuster acts purely as a mechanical travel stop to set the exact end position during commissioning; it is not a locking device. For applications requiring the load to be held securely without live air pressure, an external rod lock or the related AirTAC SAIL pneumatic lock cylinder is required.

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 SAIJ200X425-100 Is Used
Heavy Press Tuning
Dial in the exact 325-425mm travel window during heavy press commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Large Product Changeover
Quickly adjust the end-stop position on a conveyor sorting line when switching between large pallet sizes, utilizing the 100mm adjustment range to save setup time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X425-100 the Right Cylinder?
If your application requires less thrust, stepping down to a 160mm bore yields 10053N at the same pressure, but the SAIJ200X425-100 is unmatched for heavy loads. The 100mm adjustment range is particularly advantageous during product changeovers, allowing operators to dial in new end positions rapidly rather than swapping out the entire cylinder. The 40mm rod and M36x2 thread provide excellent rigidity, but because the 425mm stroke is substantial, an external guide rail is strongly recommended to prevent excessive side-loading on the rod.
When ordering, verify your configuration: a 200mm bore, 425mm stroke, 100mm adjustment range, PT G3/4 port threads, and standard carbon steel rod material. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It operates at speeds of 30-500 mm/s and is dimensionally interchangeable with other ISO 15552 profile cylinders.

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 SAIJ200X425-100 FAQ
At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective stroke from the 425mm nominal length down to 325mm. This creates a 325-425mm usable travel window for fine-tuning end positions at commissioning, but it does not lock or hold the load without live air pressure.
