Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-10S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 500mm 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 SAIJ32AX500-10S
The AirTAC SAIJ32X500-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 563N of push force at 0.7 MPa and features a 12mm SUS420J2 stainless steel rod. With a nominal 500mm stroke and a 10mm adjustment range, you can fine-tune the effective travel to any point within a 490-500mm window during commissioning.
This model includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the sensor grooves on both sides of the extruded aluminum barrel. It uses a PT tapered G1/8 port and relies on a variable air cushion at both ends to decelerate the load. The rear screw acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-10S Is Used
Product Changeover Stops
Dial in the 490-500mm travel window during product size changes on a packaging conveyor without replacing the entire actuator.
Commissioning Fine-Tuning
Trim the final 10mm of stroke at machine setup to perfectly seat a part, avoiding the need to machine custom external spacers.
Sensor Positioning
Leverage the integrated magnet and dual sensor grooves to confirm exact end-of-stroke positions within the adjusted travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX500-10S the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops; if you need less force, stepping down is not an option in this size range, but stepping up to a 40mm bore yields 879N push at 0.7 MPa. The adjustable stroke is ideal for product changeovers on a line, whereas a fixed SAI cylinder locks you into one exact dimension. To match this ISO 15552 replacement exactly, specify the 500mm stroke, 10mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
Because the 500mm stroke is relatively long for a 32mm bore, the 12mm rod and M10x1.25 thread can only handle limited side loading. An external guide rail is recommended to support the load and prevent rod binding. For applications requiring the load to be held mechanically without continuous air pressure, a plain SAIJ is insufficient; consider an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.

- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ32AX500-10S FAQ
At 0.5 MPa it provides 402N push and 345N pull force. At 0.7 MPa the push force increases to 563N, with a maximum push force of 724N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 490-500mm. It only sets the end position and does not lock the load without live air.
