About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX125-30
The AirTAC SAIJ200X125-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. With a nominal 125mm stroke and a 30mm adjustment range, it provides a usable travel window of 95-125mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
Built for durability, this configuration features a SUS304 stainless steel rod and PT tapered ports. The extruded aluminum barrel includes sensor grooves on both sides. The rear screw acts purely as a travel stop for deceleration, not a lock, so it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX125-30 Is Used
Heavy Press Tuning
Dial in the exact 95-125mm end-stop for heavy pressing tasks, accommodating material thickness variations without external stopper hardware.
Product Changeover
Quickly adjust the rear stroke screw during production line size changes to meet new travel requirements on the fly.
Large Assembly Alignment
Leverage the 15708N thrust and precise 30mm adjustment window to seat large components accurately during heavy assembly operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX125-30 the Right Cylinder?
Choose this 200mm bore cylinder when an application demands extreme force, such as 15708N push at 0.5 MPa, alongside precise 95-125mm travel tuning. If your setup requires less force, stepping down to a 160mm bore yields 10053N push force. The rear adjuster enables fine end-position shifts during product changeovers. For load-holding without live pressure, consider an external rod lock or the AirTAC SAIL lock variant, as the SAIJ adjuster is strictly a stop. Ensure an external guide supports the load to manage side loads.
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 SAIJ200BX125-30 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, creating a 95-125mm usable travel window. This stopper fine-tunes the end position but does not lock the load without live air.
