About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30S
The AirTAC SAIJ160X240-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 240 mm travel by up to 30 mm for a precise 210-240 mm usable window. It delivers substantial thrust, generating 10053 N of push force at 0.5 MPa and reaching 18095 N at 0.9 MPa. This makes it highly effective for moving heavy loads in large-scale pneumatic setups.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing. You can mount AirTAC CMSE reed or DMSE electronic solid-state switches directly into the sensor grooves on both sides of the extruded aluminum barrel. The rear stopper screw acts purely as a travel end-position setter, meaning it cannot hold a load dynamically without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30S Is Used
Heavy Fixture Positioning
Dial in the exact clamping reach on large machining fixtures using the 210-240 mm travel window, accommodating varying part sizes without retooling the entire setup.
Press Stroke Tuning
Fine-tune the end-of-stroke impact on heavy assembly presses by adjusting the rear stopper, optimizing the deceleration curve for different product profiles.
Automated Line Changeover
Rapidly adjust the extend position on automated conveyor transfer lines during product family changeovers, minimizing downtime while maintaining high force output.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30S the Right Cylinder?
Select this 160 mm bore when an application demands more force than a 125 mm cylinder, which provides 6136 N push at 0.5 MPa, but does not require the massive 15708 N output of a 200 mm unit. The adjustable stroke is ideal for machine commissioning and product changeovers, letting you fine-tune the 210-240 mm end position without swapping hardware or adding external stops. If your setup requires the load to be locked in place during an air pressure loss, pair this cylinder with an external rod lock or choose the AirTAC SAIL or BSAI locking series instead.
For a direct ISO 15552 replacement, match the 160 mm bore, 240 mm stroke, 30 mm adjustment code, PT tapered port threads, and the -S magnet option. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the 240 mm stroke is relatively short for this large bore, side-load stress is manageable, but you should still ensure the M36x2 rod thread is properly aligned with your external guide mechanism.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160BX240-30S FAQ
At 0.5 MPa it provides 10053 N of push force and 9425 N of pull force. If you increase the operating pressure to 0.9 MPa, the push force reaches 18095 N.
The rear adjuster screw lets you shorten the 240 mm nominal stroke by up to 30 mm, creating a usable travel window of 210-240 mm. This stopper sets the end position but does not lock the load without live air pressure.
