About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30S
The AirTAC SAIJ160X230-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 200 to 230 mm. Belonging to the 160 mm bore class, it generates 14074 N of push force at 0.7 MPa and 9425 N of pull force, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and operates with PT tapered ports. The integrated magnet supports position sensing via AirTAC CMSE reed or DMSE electronic switches. The rear stopper allows precise end-position tuning at commissioning without adding external stops, though it acts purely as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30S Is Used
Heavy Machinery Setup
Dial in the exact 200 to 230 mm end position during heavy machinery commissioning without machining custom external stopper blocks.
Product Size Changeover
Quickly adjust the stroke by up to 30 mm on a packaging line to accommodate different product lengths, minimizing downtime between runs.
High-Force Positioning
Leverage the 14074 N push force of the 160 mm bore to move and position heavy industrial pallets with precise end-stop control.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-30S the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust, such as 14074 N push at 0.7 MPa, alongside fine-tuned end positioning. If your setup requires less force, stepping down to a 125 mm bore yields 8590 N of push force, whereas moving up to a 200 mm bore provides 21991 N. The adjustable stroke is ideal for product changeovers, allowing you to dial back the travel by up to 30 mm without swapping the cylinder.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 160 mm bore, 230 mm nominal stroke, 30 mm adjustment range, PT port threads, and the -S magnet option. Because the nominal stroke is 230 mm, standard side-load guidelines apply, so ensure adequate external guiding for long unsupported loads. For applications requiring true load holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is a stop rather than a locking mechanism.
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 SAIJ160 Adjustable Cylinder SAIJ160BX230-30S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. The maximum push force reaches 18095 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke from its 230 mm nominal length down to 200 mm. This provides a 200 to 230 mm adjustable travel window for fine-tuning the retract end position without replacing the cylinder.
