About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10S
The AirTAC SAIJ160X40-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 40mm stroke that can be dialed back by up to 10mm, yielding a precise 30-40mm usable travel window for commissioning without external stops. The 160mm bore delivers substantial force, generating 9425N of pull at 0.5MPa and 14074N of push at 0.7MPa.\n\nThis variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance and includes a magnet for position sensing. It is compatible with AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjustment screw acts purely as a travel stop to set end-position deceleration and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10S Is Used
Press Fitment Tuning
Dial in the exact 30-40mm travel window during assembly commissioning to perfect press fits without machining external stopper blocks.
Product Changeover
Quickly adjust the end-stop position on packaging lines when switching to a new product size, minimizing machine downtime.
Heavy Load Positioning
Leverage the 14074N push force at 0.7MPa to move heavy pallets into exact final positions using the fine 10mm stroke trim.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10S the Right Cylinder?
Choose this adjustable-stroke cylinder when your application requires exact end-position tuning at machine setup or during product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. If you require less force, stepping down to a 125mm bore yields 5734N of pull at 0.5MPa, but the 160mm bore is necessary for heavy loads. Because the total travel is short, side-loading is minimal, though an external guide is always recommended for lateral forces.\n\nFor load-holding without continuous air pressure, note that the SAIJ rear adjuster and air cushions function only as stops, not brakes. You must integrate an external rod lock or pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamping cylinder. This SAIJ160X40-10-S model uses a PT tapered G3/4 port, supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, and is dimensionally interchangeable per ISO 15552.

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 SAIJ160BX40-10S FAQ
At 0.5MPa it provides 10053N push and 9425N pull force, reaching 14074N push at 0.7MPa. The 160mm bore operates at a speed range of 30-500mm/s.
The rear adjuster screw lets you mechanically shorten the stroke by up to 10mm, creating a 30-40mm usable travel window. It acts as a physical stop to fine-tune the end position and does not hold the load without live air.
