About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10
The AirTAC SAIJ160X275-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a robust 18095N push force at 0.9 MPa, making it suitable for heavy-duty operations. The integrated -10 adjustment code allows you to trim the effective travel back by up to 10 mm, creating a precise 265-275 mm usable stroke window without needing external stops.
This bore features a 40 mm piston rod with an M36x2 thread, utilizing a PT tapered port connection. The barrel is machined from extruded aluminum with sensor grooves on both sides. This unit uses a SUS304 stainless steel rod for superior corrosion resistance, and it relies on adjustable air cushions at both ends to decelerate the massive load smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10 Is Used
Heavy Machinery Setup
Fine-tune the 265-275 mm travel window during the commissioning of large presses to achieve exact bottom-dead-center positioning without mechanical shims.
Product Changeover
Quickly dial in the 10 mm stroke adjustment on a packaging line when switching between different large-format container sizes.
Material Handling
Leverage the 18095N push force to move heavy pallets, using the rear stopper to precisely set the retraction endpoint.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-10 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (providing 7068N push at 0.9 MPa) lacks the necessary thrust for heavy loads. The adjustable stroke is highly beneficial during machine commissioning or product changeover, allowing you to fine-tune the retract end position by up to 10 mm rather than swapping out a fixed-stroke SAI cylinder. When matching an ISO 15552 replacement, verify the 275 mm stroke, 10 mm adjustment range, PT port thread, and mounting style.
Because the 275 mm stroke is substantial, the long unsupported rod is susceptible to side-loading; an external guide is recommended to prevent premature seal wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air. For load-holding requirements without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ160BX275-10 FAQ
At an operating pressure of 0.9 MPa, this 160 mm bore cylinder generates a push force of 18095N and a pull force of 9425N. At 0.5 MPa, the push force is 10053N.
The rear adjuster screw allows you to shorten the nominal 275 mm stroke by up to 10 mm, providing an effective travel range of 265 to 275 mm. This stopper decelerates the load but does not lock it in place without continuous air pressure.
