Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-100
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X275-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 275mm 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 SAIJ200X275-100
The AirTAC SAIJ200X275-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 275 mm nominal travel to any point within a 175-275 mm usable window. The extruded aluminum barrel integrates sensor grooves on both sides, ready for CMSE reed and DMSE electronic switches if a magnet is specified later.
This adjustable-stroke design eliminates the need to swap out the entire cylinder or bolt on external stopper blocks when fine-tuning end positions during commissioning. The 40 mm carbon steel piston rod and M36x2 thread provide a robust interface for heavy loads, while the standard PT G3/4 porting handles the high air volume required for motion. The rear adjustment screw acts purely as a mechanical travel stop, meaning it does not lock or hold the load without continuous live air pressure.

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 SAIJ200X275-100 Is Used
Heavy Press Fine-Tuning
Dial in the exact 175-275 mm end position during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Size Changeover
Quickly adjust the stroke window up to 100 mm on automated packaging lines when switching between different large product dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-100 the Right Cylinder?
The 100 mm adjustment range is ideal for product-size changeovers on heavy machinery, allowing operators to reposition the end-of-stroke limit precisely without changing the cylinder. For true load-holding without live air, select the SAIL air-released lock or BSAI clamp-lock series instead, as the SAIJ adjuster only sets the travel end.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 275 mm stroke, 100 mm adjustment range, PT G3/4 port thread, and required mounting accessories. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. Because the 275 mm stroke is substantial, always use an external guide to prevent excessive side-loading on the long unsupported rod.
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 SAIJ200X275-100 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, providing a usable travel window of 175 to 275 mm. It acts as a mechanical stop to tune the end position, but it does not hold the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, the push force reaches 3204 kgf.
