About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75
The AirTAC SAIJ160X290-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. It features a 160 mm bore, a SUS304 stainless steel rod, and a 75 mm adjustment range, creating a usable travel window between 215 mm and 290 mm. This eliminates the need to swap cylinders or bolt on external stops when dialing in a machine setup.
Belonging to a high-force class, it delivers 10053 N of push thrust and 9425 N of pull thrust at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and because this configuration omits the standard magnet, you would add an -S suffix if you later require CMSE reed or DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to set the deceleration point, meaning it will not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75 Is Used
Heavy Machinery Changeover
Adjust the 215-290 mm retract window on the fly to accommodate different product sizes on a heavy assembly line without changing the cylinder.
Precision End-Stop Tuning
Dial in the exact end position during machine commissioning using the rear screw, avoiding the need to fabricate and install external mechanical stops.
High-Force Positioning
Leverage the 10053 N push force at 0.5 MPa to move substantial loads while retaining the ability to trim the stroke by up to 75 mm for setup flexibility.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX290-75 the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 2513 N push at 0.5 MPa) lacks the power for heavy moving masses, but a 200 mm bore is physically oversized. The 75 mm adjustment window is ideal for product-size changeovers on a line, letting you shift the retract end-stop without machining new hard stops. For load-holding without continuous air pressure, this cylinder is insufficient; you should specify a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock instead of relying on the adjuster.
To match this exact ISO 15552 interchangeable replacement, confirm the 160 mm bore, 290 mm nominal stroke, 75 mm adjustment code, PT tapered port threads, and the SUS304 (code B) rod material. Because the 290 mm stroke is substantial, the 40 mm rod diameter and M36x2 thread provide rigidity, but long unsupported strokes still require an external guide to prevent excessive side-loading. Available mountings include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX290-75 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 15708 N.
The rear adjuster screw acts as a stop that lets you shorten the effective travel from the 290 mm nominal stroke down to as little as 215 mm. It sets the travel end for deceleration but does not lock or hold the load without live air pressure.
