Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-40S
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X325-40S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 325mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-40S
The AirTAC SAIJ200X325-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet supports CMSE reed and DMSE electronic solid-state switches.
This 200 mm bore model uses a G3/4 port and a robust 40 mm carbon steel rod with an M36x2 thread, providing high structural rigidity. The rear adjuster acts purely as a mechanical stop to set the retract position during commissioning or product changeover without adding external stops. It is not a locking device, so live air pressure must be maintained to hold the load; for dead-air holding, consider the SAIL or BSAI series.

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 SAIJ200X325-40S Is Used
Heavy Press Tuning
Dial in the exact 285-325 mm end-stop during machine setup to accommodate varying material thicknesses without swapping out the entire actuator.
Product Changeover Stops
Adjust the retract position on the fly during packaging line changeovers to handle different pallet sizes using the 40 mm travel window.
Large Assembly Positioning
Move heavy 1500 kgf loads into place and fine-tune the final resting position at commissioning using the rear mechanical stopper.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-40S the Right Cylinder?
Select this 200 mm bore cylinder when an application demands extreme thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The adjustable stroke is chosen over a fixed SAI model when you need variable end-stops to accommodate different product sizes on a single line. Because the 325 mm stroke is long, the 40 mm rod and M36x2 thread handle significant side loads, but an external guide rail is still recommended for heavy unsupported loads.
To replace an ISO 15552 cylinder, match the 200 mm bore, 325 mm base stroke, 40 mm adjustment range, PT tapered G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR brackets found on some standard profiles.
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 SAIJ200X325-40S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 325 mm nominal stroke by up to 40 mm. This provides a usable travel window of 285-325 mm for fine-tuning the end position without adding external stops.
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf of push force.
