About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-10
The AirTAC SAIJ200X325-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel integrates sensor grooves on both sides for flexible switch mounting.
This heavy-duty actuator uses a substantial 40mm carbon steel rod with an M36x2 thread, paired with 50mm variable air cushions at both ends to manage heavy kinetic energy. The rear adjustment screw functions purely as a mechanical stop to dial in the end position during commissioning; it does not lock the load without live air pressure. For load-holding requirements, an external rod lock or SAIL series 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 SAIJ200X325-10 Is Used
Heavy Press Fine-Tuning
Dial in the exact 315-325mm end position during heavy press commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the 10mm stroke window on the rear screw to accommodate slight variations in large product sizes on the line.
Large Assembly Setup
Set precise end-stops for massive 200mm bore assembly processes, relying on the 50mm cushions to absorb high kinetic energy.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-10 the Right Cylinder?
Choose this 200mm bore actuator when an application requires massive thrust—stepping down to a 160mm bore drops the 0.5MPa push force to 10053N. The SAIJ200X325-10 is selected over a fixed-stroke SAI when a 10mm external trim is needed to perfect machine setup or product changeovers without swapping the cylinder. The PT tapered porting and G3/4 thread size match the bore's high flow requirements.
When replacing an ISO 15552 cylinder, match the 200mm bore, 325mm stroke, 10mm adjustment range, PT port, and standard carbon steel rod. Because the stroke is 325mm, the long unsupported piston rod is susceptible to side-loading; an external guide rail should be used to prevent premature seal wear. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. This model lacks a magnet; position sensing requires adding the -S option for CMSE reed or DMSE electronic sensors.
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 SAIJ200X325-10 FAQ
It can reach a maximum push force of 3204 kgf at 1.0MPa.
The rear adjuster acts as a mechanical stop that trims the 325mm stroke back by up to 10mm, creating a 315-325mm travel window. It sets the end position but does not hold the load without live air pressure.
