About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-20S
The AirTAC SAIJ32X375-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 375 mm stroke that can be fine-tuned backward by up to 20 mm, creating a precise 355-375 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks. This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for CMSE or DMSE sensors.
Because the stroke extends to 375 mm on a 32 mm bore, the 12 mm rod requires external guidance to prevent excessive side-loading. The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure. For load-holding requirements, consider an external rod lock or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-20S Is Used
Machine Changeover
Quickly adjust the 355-375 mm end-stop during product size changes on a packaging line without replacing the cylinder.
Light-Duty Positioning
Utilizes 402 N of thrust at 0.5 MPa to push light parts accurately, with a SUS304 rod for corrosive environments.
Variable End Stops
Fine-tune the retraction point during commissioning to perfectly meet varying conveyor lengths or product profiles.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX375-20S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa with on-the-fly end-position tuning. If your application requires higher thrust, stepping up to the 40 mm bore yields 628 N. The adjustable stroke is ideal for machine changeovers, allowing you to dial in the 355-375 mm window without swapping cylinders or adding external stops. Unlike a fixed SAI cylinder, the SAIJ rear screw enables precise commissioning.
To match this exact configuration for an ISO 15552 replacement, specify the 32 mm bore, 375 mm stroke, 20 mm adjustment, PT tapered port, and the -S magnet. Note that long strokes like 375 mm mandate a external guide to protect the 12 mm rod from side-load wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

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 SAIJ32BX375-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At a maximum 1.0 MPa, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 375 mm stroke by up to 20 mm, providing a usable travel window of 355 to 375 mm. This stopper only sets the end position and does not lock the load without air pressure.
