Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 165mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30S
The AirTAC SAIJ32X165-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 135-165 mm usable travel window, letting you dial back the 165 mm nominal stroke by up to 30 mm during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa, making it well-suited for lighter-duty positioning tasks.
This variant ships with a SUS304 stainless steel rod for corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads match standard pneumatic plumbing. The rear adjuster acts purely as a travel stop to fine-tune end positions; it does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30S Is Used
Machine Changeover
Dial in the exact 135-165 mm end position during product size changeovers without swapping out the entire cylinder or adding external shims.
Sensor-Ready Positioning
Leverage the -S magnet and dual barrel grooves to mount CMSE or DMSE sensors for precise end-of-stroke detection in automated assembly.
Light-Duty Clamping
Apply up to 402 N of push force at 0.5 MPa for delicate holding or clamping tasks where the contact point must be finely adjusted.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX165-30S the Right Cylinder?
Choose this 32 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning at setup or during product changeovers. If you need greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. The integrated 30 mm adjustment window is ideal for machinery where fixed SAI cylinders would require custom spacers or repeated physical repositioning to achieve the exact stroke length.
Because the 165 mm stroke is under the 300 mm threshold, side-load stress on the 12 mm rod is minimal, though long unsupported loads should still use an external guide. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. For load-holding without continuous air pressure, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead, as the rear stopper here is not a brake.

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 SAIJ32BX165-30S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 165 mm nominal stroke down to as little as 135 mm. This creates a 30 mm adjustable window for fine-tuning the retract position without swapping the cylinder.
At 0.5 MPa operating pressure, it provides 402 N of push force and 345 N of pull force. The standard speed range for this 32 mm bore is 30-800 mm/s, operating within the ISO 15552 dimensional interface.
