About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-20S
The AirTAC SAIJ160X80-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 60 to 80 mm for precise end-position tuning. It belongs to the 160 mm bore class, generating 10053 N of push force and 9425 N of pull force at 0.5 MPa. This makes it highly effective for moving substantial loads in heavy-duty automation setups.
This specific configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a built-in magnet (-S) for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and fluid control is managed via a G3/4 PT port.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 60 to 80 mm travel end-point during setup to accommodate material thickness variations without swapping out the entire actuator.
Product Size Changeover
Quickly adjust the rear stopper on a production line when switching between different product sizes, minimizing machine downtime.
Corrosive Heavy Load Handling
Leverage the 10053 N thrust and SUS304 stainless steel rod for robust positioning tasks in environments where moisture or corrosive elements are present.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX80-20S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires heavy thrust up to 10053 N at 0.5 MPa but needs the exact end-of-stroke position dialed in during commissioning without adding external stops. If the load requires less force, stepping down to a 125 mm bore yields 6136 N of push force. The adjustable rear screw acts purely as a travel stop and does not lock the load; for position holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. To replace this cylinder with another ISO 15552 unit, match the 160 mm bore, 80 mm stroke, 20 mm adjustment, G3/4 PT port, SUS304 rod, and the -S magnet.
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 SAIJ160BX80-20S FAQ
At an operating pressure of 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 80 mm stroke by up to 20 mm, creating a usable travel window of 60 to 80 mm. This stopper fine-tunes the end position but does not hold the load without continuous air pressure.
