Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 475mm 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 SAIJ32AX475-75
The AirTAC SAIJ32X475-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 400-475mm, allowing you to dial back the 475mm nominal stroke by up to 75mm during commissioning. Delivering 402N of pull force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant uses a SUS420J2 stainless steel piston rod (code A) for improved corrosion resistance over standard carbon steel. It features PT tapered port threads (G1/8) and lacks a standard magnet, meaning position sensing via CMSE reed or DMSE electronic switches is not supported without modification. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75 Is Used
End-Position Tuning
Dial in the exact retract distance within the 400-475mm window during machine commissioning without swapping cylinders.
Product Changeover
Quickly adjust the retract stop to accommodate varying product sizes on a single conveyor line.
Light-Duty Positioning
Utilize the 402N pull force for precise, lighter-load handling tasks requiring variable end-stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-75 the Right Cylinder?
Choose this 32mm bore when you need precise retract-end tuning without adding external mechanical stops. If your application requires higher thrust, stepping up to the 40mm bore yields 528N of pull force at 0.5 MPa. The rear adjuster acts strictly as a travel stop to fine-tune the end position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.
Because the 475mm stroke is relatively long for a 32mm bore, the 12mm diameter rod is susceptible to side-loading. An external guide is recommended to prevent binding over extended travel. This SAIJ model maintains ISO 15552 mounting interchangeability and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (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 SAIJ32AX475-75 FAQ
The nominal stroke is 475mm, but the rear adjuster allows you to shorten the effective stroke by up to 75mm, creating a usable travel window of 400-475mm.
At 0.5 MPa, this 32mm bore cylinder provides 402N of pull force and 563N of push force. It can reach a maximum push force of 724N at 0.9 MPa.
