About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-75
The AirTAC SAIJ160X425-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 425 mm travel by up to 75 mm. This creates a usable end-position window of 350-425 mm, giving you precise control over the retract distance without needing external stops. Built with a SUS304 stainless steel rod, it handles heavy loads reliably while resisting corrosion.
Operating at 0.5 MPa, this 160 mm bore generates 9425 N of pull force and 10053 N of push force, scaling up to 18095 N push at 0.9 MPa. The extruded aluminum barrel features sensor grooves on both sides, and with a 425 mm stroke, the robust 40 mm rod and M36x2 thread provide excellent structural support to minimize side-load deflection. It uses PT tapered ports and includes adjustable air cushions at both ends to decelerate heavy masses smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-75 Is Used
Heavy Press Tuning
Fine-tune the 350-425 mm retract distance on large metal forming presses during setup, ensuring precise positioning without machining new stop blocks.
Product Changeovers
Adjust the end-stop by up to 75 mm on packaging lines to accommodate different large-format carton sizes quickly and efficiently.
Material Handling
Leverage the 10053 N push force to move heavy pallets or structural components, using the rear screw to dial in the exact transfer position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX425-75 the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder lacks thrust, as the SAIJ160 provides 10053 N push force at 0.5 MPa compared to 2513 N from the smaller bore. The 75 mm adjustment range is ideal for product changeovers on large machinery, letting operators fine-tune the retract end-stop during commissioning rather than swapping out the entire cylinder. Because the 425 mm stroke exceeds 300 mm, an external guide should be used to support the load and prevent excessive side loading on the rod.
For an exact ISO 15552 replacement, match the 160 mm bore, 425 mm stroke, 75 mm adjustment, PT port thread, and SUS304 rod material. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ160BX425-75 FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm. This provides a usable travel window of 350-425 mm, allowing you to fine-tune the retract position at commissioning without adding external stops.
At 0.5 MPa, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
