About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X225-75S
The AirTAC SAIJ200X225-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 150-225 mm window. Equipped with a standard -S magnet, it integrates seamlessly with AirTAC CMSE reed and DMSE electronic sensors mounted in the dual-side barrel grooves. As the largest bore in the SAIJ range, it generates a substantial 15708 N pull force at 0.5 MPa and reaches 3204 kgf at 1.0 MPa.
This adjustable design eliminates the need to swap out the entire cylinder or bolt on external stops when dialing in the retract end-position during machine commissioning. The rear screw acts purely as a mechanical travel stop to set the deceleration point alongside the variable air cushions; it does not hold the load without live air pressure. For applications requiring true load-holding without continuous air supply, you should explore the SAIL pneumatic lock or BSAI clamp-lock variants.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X225-75S Is Used
Heavy Machinery Setup
Dial in the exact retract position of large actuators during heavy equipment assembly without swapping cylinders or adding external stop blocks.
Product Size Changeover
Quickly adapt a high-force production line to different product dimensions by adjusting the travel window from 150 to 225 mm.
High-Force End Tuning
Fine-tune the end-of-stroke deceleration point on a 15708 N pull application to prevent impact damage during commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X225-75S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application requires extreme thrust, stepping up significantly from the 160 mm bore which yields 9425 N pull at 0.5 MPa. The 75 mm adjustment range is ideal for product-size changeovers on a line, allowing operators to dial in the exact retract distance without replacing hardware. Because this is a 225 mm stroke, it falls below the 1500 mm maximum standard stroke for this bore, meaning it is a standard offering rather than a made-to-order item.
When ordering, confirm the exact configuration: a 200 mm bore, 225 mm stroke, 75 mm adjustment range, PT tapered port threads, and the -S magnet option. It utilizes the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting the FB, CA, CB, and CR brackets. Although the stroke is under 300 mm, the heavy forces generated by this bore mean an external guide is still recommended for any significant side-loading scenarios.
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 SAIJ200X225-75S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of pull force and 21991 N of push force. At its maximum 1.0 MPa operating pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the nominal 225 mm stroke by up to 75 mm, providing a usable travel window of 150 to 225 mm. It sets the travel end and works with the air cushions for deceleration, but it does not lock or hold the load without live air pressure.
