About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-10
The AirTAC SAIJ160X350-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the retract end position by up to 10 mm. This creates a precise 340-350 mm usable travel window, ideal for dailing in final positioning during commissioning without adding external stops. Built with a SUS304 stainless steel rod, it handles heavy loads with 14074 N of push force at 0.7 MPa.
This model features PT tapered ports and operates at speeds between 30-500 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. While the rear screw sets the travel limit and the air cushions decelerate the piston, neither component acts as a lock to hold the load without continuous air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-10 Is Used
Heavy Press Tuning
Dial in the exact bottoming position of a large forming press within the 340-350 mm window to compensate for material thickness variations.
Pallet Changeover Stops
Adjust the retract stopper by up to 10 mm during production line format changes to accommodate different pallet widths without swapping hardware.
Large Fixture Clamping
Secure heavy automotive or structural components during machining, relying on the 14074 N push force at 0.7 MPa for rigid, high-tonnage clamping.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX350-10 the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 3518 N push at 0.5 MPa) lacks the thrust for heavy positioning tasks, but before stepping up to a massive 200 mm bore. The 10 mm adjustment range is perfect for applications needing slight end-position tweaks during product changeovers, offering flexibility that a fixed-stroke SAI cylinder cannot provide. Because the 350 mm stroke is substantial, the 40 mm rod diameter handles significant side loads, though an external guide rail is still recommended for optimal bearing life.
For a drop-in ISO 15552 replacement, match the 160 mm bore, 350 mm stroke, 10 mm adjustment, PT port thread, and your required mounting style. SAIJ supports a specific subset of mounts: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that this SKU does not include a magnet; if you require position sensing, you must select an -S variant to use CMSE reed or DMSE electronic sensors. If your application requires true load-holding without live air, consider an AirTAC SAIL or BSAI cylinder instead.

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 SAIJ160BX350-10 FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 14074 N of push force and 13234 N of pull force. At a maximum 1.0 MPa, the push force reaches 18095 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 350 mm stroke by up to 10 mm, resulting in a 340-350 mm usable travel window. This stopper sets the end position but does not lock the load without live air pressure.
