Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-10S
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 425mm 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 SAIJ32AX425-10S
The AirTAC SAIJ32X425-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 415-425mm usable travel window, allowing you to trim the effective stroke by up to 10mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet supports CMSE reed and DMSE electronic solid-state switches for precise position detection.
This model uses a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and pairs with PT tapered port threads (G1/8). The rear adjuster acts purely as a mechanical stop to fine-tune the end position without swapping the cylinder, while the variable air cushions at both ends manage deceleration. Remember that neither the adjuster nor the cushion holds the load without live air pressure; for true load-holding, consider an external rod lock or the SAIL series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-10S Is Used
End-Stop Calibration
Dial in the exact 415-425mm retraction point during machine setup to accommodate varying material thicknesses without replacing the actuator.
Product Changeover
Quickly adjust the stroke stop by up to 10mm on packaging lines when switching between different product sizes, minimizing downtime.
Sensor-Driven Positioning
Leverage the integrated -S magnet with DMSE electronic sensors to confirm the adjusted end position in automated assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX425-10S the Right Cylinder?
Select this 32mm bore cylinder when an application requires precise end-position tuning on a 425mm stroke, avoiding the need to bolt on external stops or swap components during product changeovers. If your setup needs greater thrust, stepping up to the 40mm bore provides 628N of push force at 0.5 MPa. Because this is a 425mm stroke, the 12mm diameter rod and M10x1.25 rod thread will experience leverage forces under side loading; an external guide mechanism is recommended to prevent premature seal wear.
For an exact ISO 15552 replacement match, verify a 32mm bore, 425mm stroke, 10mm adjustment range, PT port thread, and the -S magnet option. This SAIJ configuration supports the Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting set, omitting FB, CA, CB, and CR brackets. The operating speed ranges from 30-800 mm/s.

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 SAIJ32AX425-10S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If operated at 0.7 MPa, the push force increases to 563N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 425mm nominal stroke by up to 10mm, creating a 415-425mm usable travel window. It only sets the travel end and does not lock the load without live air pressure.
