About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-50S
The AirTAC SAIJ200X350-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a massive 3204 kgf maximum thrust at 1.0 MPa. The 50 mm adjustment code creates a usable travel window between 300 and 350 mm, allowing you to dial back the endpoint during commissioning without adding external stops.
This 200 mm bore unit features a robust 40 mm carbon steel rod and M36x2 thread. PT tapered ports (G3/4) manage the high air volume required for moving heavy loads. The extruded aluminum barrel includes sensor grooves on both sides, and the included -S magnet works directly with AirTAC CMSE reed and DMSE electronic switches.

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 SAIJ200X350-50S Is Used
Heavy Press Tuning
Dial in the exact 300-350 mm end position for large metal forming or heavy pressing tasks without swapping out the entire actuator.
Pallet Changeover
Adjust the rear stopper on the fly to accommodate different pallet sizes or product widths on a heavy-duty transfer line.
Large Assembly Setup
Precisely set the retraction end-point for heavy automotive or industrial machinery assembly during initial machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-50S the Right Cylinder?
Select this 200 mm bore actuator when an application demands extreme force that smaller neighbors cannot provide, such as stepping up from a 160 mm bore that yields 2050 kgf. The rear adjuster acts purely as a mechanical stop to fine-tune the 300-350 mm travel window during product changeovers. It does not lock or hold the load without live air pressure; for true load-holding, consider an external pilot-operated check valve or an AirTAC SAIL cylinder.
Because the 350 mm stroke is substantial and the 40 mm rod carries significant mass, an external guide is recommended to prevent side-loading damage on long unsupported strokes. To match this ISO 15552 footprint exactly, specify the 200 mm bore, 350 mm stroke, 50 mm adjustment, PT ports, and the -S magnet option.
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 SAIJ200X350-50S FAQ
At the maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates a push force of 3204 kgf.
The rear adjuster allows you to shorten the nominal 350 mm stroke by up to 50 mm, creating a usable travel window of 300 to 350 mm. This stopper only sets the end position; it does not hold the load without continuous air pressure.
