About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40
The AirTAC SAIJ160X200-40 is a double-acting, single-rod profile cylinder dimensionally interchangeable per ISO 15552. It features an extruded aluminum barrel with sensor grooves on both sides, a 40mm carbon steel rod, and PT (tapered) G3/4 ports. A rear-mounted adjusting screw allows you to shorten the nominal 200mm stroke by up to 40mm, creating a precise 160-200mm usable travel window for commissioning without external stops.
Delivering 10053N of pull force at 0.5MPa and up to 18095N at 0.9MPa, this unit handles heavy loads within a 30-500mm/s speed range. The robust 40mm rod and M36x2 thread provide excellent resistance to side-loading, while the standard air cushions at both ends manage deceleration. For position holding without live air pressure, consider the SAIL or BSAI series, as this adjuster acts strictly as a travel stop.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40 Is Used
Heavy Press Tuning
Dial in the exact 160-200mm travel window during assembly commissioning to ensure heavy pressing operations hit the correct depth without adding external physical stops.
Product Changeover
Quickly adjust the retract end-position by up to 40mm on packaging machinery when switching product sizes, saving downtime compared to physically replacing the cylinder.
Material Handling
Leverage the 18095N push force at 0.9MPa to move heavy pallets or structural components, relying on the 40mm carbon steel rod to withstand demanding industrial loads.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X200-40 the Right Cylinder?
Choose this 160mm bore when your application requires substantial thrust (10053N pull at 0.5MPa) alongside a variable end-stop. The -40 adjustment code is ideal for dialing in a 160-200mm travel window during machine setup or product changeover, preventing the need to swap cylinders. If your force requirements are lower, stepping down to a 125mm bore yields 5734N pull, whereas moving up to a 200mm bore provides 15080N. When replacing an ISO 15552 cylinder, match the 160mm bore, 200mm stroke, 40mm adjustment, G3/4 PT ports, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). No magnet is included, so position sensing requires adding a -S variant for CMSE or DMSE switches.

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 SAIJ160X200-40 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 40mm from the nominal 200mm stroke. This creates a 160-200mm usable travel window, allowing fine end-position tuning at commissioning without swapping the cylinder.
At 0.5MPa it provides 10053N pull and 9425N push. At 0.9MPa the push force reaches 18095N, making it suitable for heavy-duty industrial applications.
