About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-50
The AirTAC SAIJ200X275-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. By turning the rear stopper screw, you can trim the effective travel back by up to 50mm, creating a precise 225-275mm usable window without changing the cylinder or bolting on external stops.
This heavy-duty actuator features a PT tapered G3/4 port and variable air cushions at both ends to decelerate high kinetic loads. The extruded aluminum barrel includes sensor grooves on two sides. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load 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 SAIJ200X275-50 Is Used
Heavy Press Tuning
Fine-tune the 225-275mm stroke window during heavy press commissioning to achieve exact material deformation without swapping out the entire actuator.
Product Size Changeovers
Quickly adapt machinery end-stops for different large product dimensions on a production line by dialing the rear adjuster up to 50mm.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X275-50 the Right Cylinder?
The 50mm adjustment range is highly valuable in heavy machinery setups where you need to dial in the exact end position during commissioning or product-size changeovers. Because the 275mm stroke is substantial, always support the load with an external guide to prevent side-loading damage to the 40mm carbon steel rod.
When replacing an ISO 15552 cylinder, match the 200mm bore, 275mm nominal stroke, 50mm adjustment, PT G3/4 port, and carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR. Since no magnet is specified, position sensing via CMSE or DMSE switches is not possible without upgrading to an -S variant.
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 SAIJ200X275-50 FAQ
The rear stopper screw allows you to shorten the 275mm nominal stroke by up to 50mm, giving an effective travel window of 225-275mm. The adjuster acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
