About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100S
The AirTAC SAIJ160X290-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. By turning the rear stopper screw, you can trim the forward travel anywhere within a 190 to 290 mm usable window. This allows precise end-position tuning during commissioning without swapping out the cylinder or adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and carries PT tapered port threads (G3/4). The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions purely as a travel stop to set deceleration, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100S Is Used
Product Changeover
Dial in a new 190 to 290 mm end-stop during format size changes on a packaging line without physically replacing the actuator.
Machine Setup
Fine-tune the final extended position during commissioning to perfectly mate with tooling, absorbing mechanical tolerances on the fly.
Heavy Forming
Leverage the 10053N push force at 0.5 MPa for pressing or holding heavy components, using the rear screw to set the exact travel limit.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore falls short on power (the 80 mm yields 2513N push at 0.5 MPa, whereas this 160 mm provides 10053N). The 100 mm adjustment range is ideal for machines handling frequent product-size changeovers, allowing operators to dial in a new end-stop on the fly rather than machining new hard stops. Because the nominal stroke is 290 mm, an external guide is recommended to prevent excessive side-loading on the piston rod.
To match this ISO 15552 interchangeable cylinder for a replacement, verify the 160 mm bore, 290 mm nominal stroke, 100 mm adjuster, PT G3/4 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. If your application requires true load-holding without continuous air pressure, consider the SAIL locking cylinder or BSAI clamp-lock instead of relying on the adjuster.
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 SAIJ160BX290-100S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm. This creates a usable travel window of 190 to 290 mm from the 290 mm nominal stroke, allowing you to set the exact end position without adding external stops.
