About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75S
The AirTAC SAIJ32X170-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 170 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a highly flexible 95-170 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. It uses a PT tapered G1/8 port and relies on the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75S Is Used
Machine Commissioning
Dial in the exact 95-170 mm end position during setup without swapping cylinders or machining external stoppers.
Product Changeover
Quickly adjust the retract stop distance on packaging lines when handling different product sizes on the fly.
Variable End Stops
Set precise retraction limits for delicate pick-and-place operations using the 75 mm rear adjustment screw.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX170-75S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and you need to dial in the exact end-of-stroke position during commissioning without adding external stops. If your setup demands less force, stepping down is not an option in this frame size, but stepping up to a 40 mm bore increases the push force to 628 N. The rear adjuster acts purely as a travel stop for deceleration; it does not hold the load without live air pressure. For secure load-holding without continuous air, consider an SAIL air-released lock or BSAI clamp-lock cylinder.
Because the 170 mm stroke is below the 300 mm threshold, side-loading stress on the 12 mm rod is moderate, but an external guide is still recommended for heavy offset loads. This configuration is dimensionally interchangeable per ISO 15552, featuring a PT port thread and an -S magnet for position sensing.

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 Adjustable Cylinder SAIJ32 SAIJ32BX170-75S FAQ
It features a rear adjusting screw that acts as a stopper, allowing you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 95 to 170 mm, enabling fine-tuning of the end position without replacing the cylinder.
At a 0.5 MPa operating pressure, the SAIJ32X170-75-S generates 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
