About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100
The AirTAC SAIJ160X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, pushing 10053N at 0.5 MPa, and uses a PT G3/4 port with a robust 40mm rod. By turning the rear stopper screw, you can trim the effective travel anywhere within a 190-290mm window, providing exact end-position tuning during commissioning without swapping hardware.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and carries a 50mm adjustable air cushion at both ends to decelerate heavy loads. The rear adjuster acts purely as a mechanical stop to set the travel limit; it does not lock or hold the load without continuous live air pressure. For position-holding requirements, an external rod lock or a related SAIL pneumatic-lock cylinder is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100 Is Used
Product Changeover
Dial in the 190-290mm travel window during format size changes on heavy packaging equipment without replacing the cylinder.
Heavy Press Tuning
Fine-tune the exact end-of-stroke pressing position during machine commissioning to prevent over-travel on high-force tasks.
Guided Lifting
Adjust the retract stop for varying lift heights in material handling, relying on external guides to support the 40mm rod under load.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-100 the Right Cylinder?
Select this 160mm bore when an application demands high force (10053N push at 0.5 MPa) alongside variable end-stops, such as accommodating different product sizes on a single line. If your setup only requires standard fixed travel, a conventional SAI cylinder simplifies the assembly, while stepping down to a 125mm bore reduces the footprint and force to 6136N.
Because the 290mm stroke exceeds 300mm only slightly, evaluating side-load is still prudent: the 40mm rod handles higher bending moments, but an external guide rail is recommended for heavy off-center loads. To match this exact ISO 15552 footprint, verify the 160mm bore, 290mm nominal stroke, 100mm adjustment range, PT G3/4 port, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This configuration omits a magnet, so position sensing requires adding a -S variant to use CMSE reed or DMSE electronic switches.

- ✓ 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 SAIJ160BX290-100 FAQ
The rear stopper screw allows you to mechanically shorten the nominal 290mm stroke by up to 100mm, providing an effective usable travel window of 190-290mm. This enables precise end-position tuning at commissioning without adding external stops.
At 0.5 MPa operating pressure, it provides 10053N of push force and 9425N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 2050 kgf.
