About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20S
The AirTAC SAIJ160X290-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 270 to 290 mm. Delivering 14074 N of push force at 0.7 MPa, it handles heavy-duty positioning with precision. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE or DMSE sensors. Because the rear adjuster acts as a travel stop rather than a lock, it decelerates the load at the end of stroke but requires live air or an external rod lock to hold position safely.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20S Is Used
Heavy Machinery Setup
Fine-tune the 270-290 mm travel window during heavy machinery commissioning to achieve exact positioning without swapping components.
Product Changeover
Adapt end-stops quickly on a production line when changing product sizes, utilizing the 20 mm rear adjustment screw for rapid format transitions.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for heavy pushing tasks in washdown or corrosive manufacturing environments requiring precise travel limits.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-20S the Right Cylinder?
Select this 160 mm bore cylinder when an 80 mm bore (providing 3518 N push at 0.7 MPa) lacks the thrust for your application, but you need precise end-position tuning during commissioning without adding external stops. The PT tapered port threads ensure a robust pneumatic seal, while the SUS304 rod withstands harsh environments. For a fixed end position without the need for commissioning adjustments, a standard SAI cylinder is sufficient.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 290 mm stroke, 20 mm adjustment range, PT port thread, and the -S magnet requirement. Given the 290 mm stroke, ensure adequate external guiding to prevent excessive side loading on the rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ160BX290-20S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides 14074 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 allows you to shorten the nominal 290 mm stroke by up to 20 mm, creating a 270-290 mm usable travel window. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
