About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-50
It features a 350mm nominal stroke equipped with a rear mechanical adjuster, creating a precise 300-350mm usable travel window. This built-in stopper allows you to fine-tune the retract end position during commissioning without swapping out the entire cylinder or fabricating external stops.
Constructed with a robust 40mm carbon steel rod and M36x2 threading, this 200mm bore unit handles significant loads, though its 350mm stroke necessitates an external guide to prevent excessive side-loading on the rod. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE or DMSE switches, and it utilizes PT tapered port threads (G3/4) for secure pneumatic connections.

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 SAIJ200X350-50 Is Used
Heavy Press Tuning
Dial in the exact 300-350mm end position during heavy press commissioning to accommodate material thickness variations without machining custom spacers.
Product Changeover
Rapidly adjust the retract distance on a conveyor sorting arm when switching between different pallet sizes, utilizing the 50mm trim range for quick line setup.
Variable End Stops
Establish precise mechanical end limits for large automated assembly stations, ensuring repeatable positioning even if sensor placement shifts over time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-50 the Right Cylinder?
The 50mm adjustment range is ideal for production lines requiring frequent product-size changeovers, offering variable end-stops without the need to inventory multiple fixed-stroke SAI cylinders. When integrating this ISO 15552 dimensionally interchangeable unit, ensure your mounting choice uses the SAIJ compatible set: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR configurations are omitted.
Because the stroke is 350mm, an external guide is mandatory to support the load and prevent rod binding. Furthermore, recognize that the rear adjuster acts solely as a travel stop and the variable air cushions only manage deceleration; neither component will hold the load without continuous live air pressure. For true load-holding capabilities without air, consider the SAIL or BSAI variants, or employ an external rod lock.
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 SAIJ200X350-50 FAQ
At the maximum rated pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a mechanical stop that trims the effective stroke back from the 350mm nominal length, providing a usable travel window of 300-350mm. It sets the end position but does not lock the load without live air pressure.
