About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-100
The AirTAC SAIJ200X400-100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It delivers massive thrust, pushing with 28274N at 0.9 MPa, while utilizing a standard G3/4 port and a robust 40mm carbon steel rod. An integrated rear adjusting screw allows you to shorten the effective travel, providing a usable stroke window of 300-400mm to perfectly dial in end positions during commissioning.
This adjustable stopper enables fine end-position tuning without swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides, and while this unit omits the magnet option, the design supports AirTAC CMSE (reed) and DMSE (electronic) switches when needed. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

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 SAIJ200X400-100 Is Used
Heavy Stamping Alignment
Dial in the exact 300-400mm travel window during heavy stamping setups to accommodate different die heights without changing the cylinder.
Large Product Diversion
Adjust the retract end-stop on the fly for varying pallet sizes on a conveyor line, ensuring precise routing of heavy loads.
Press Tonnage Setup
Fine-tune the bottom dead center of a pneumatic press during commissioning, utilizing the 3204 kgf max force to find the optimal crush depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X400-100 the Right Cylinder?
If your setup only needs moderate thrust, stepping down to a 160mm bore yields 9425N pull at 0.5 MPa, but the SAIJ200X400-100 is unmatched for high-load tasks. Because the 400mm stroke is substantial, an external guide is recommended to manage side loads on the long, unsupported rod.
An adjustable stroke is ideal for machine setups where the exact end-stop varies, saving the cost of machining custom external stopper blocks. For load-holding without continuous live air pressure, this cylinder is insufficient since the rear adjuster is a stop, not a brake; consider an AirTAC SAIL or BSAI cylinder instead. To match this ISO 15552 interchangeable cylinder, specify the 200mm bore, 400mm stroke, 100mm adjustment, PT tapered ports, and your preferred mounting from the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2.

- ✓ 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 SAIJ200X400-100 FAQ
At 0.9 MPa, the push force increases to 28274N.
The rear adjuster screw lets you trim the nominal 400mm stroke back by up to 100mm, creating a usable travel window of 300-400mm. It functions as a mechanical stop for end-position tuning and is not a lock.
