Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 25mm 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 SAIJ32AX25-10
The AirTAC SAIJ32X25-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window down to 15-25 mm from a 25 mm nominal stroke. Delivering 402 N of push force at 0.5 MPa, it provides precise end-position tuning without requiring external stops. This configuration includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses PT tapered port threads.
Unlike fixed-stroke SAI cylinders, the SAIJ rear screw lets you dial in the exact retract distance during machine commissioning or product changeovers. The adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and because no magnet is specified, it will not directly interface with CMSE reed or DMSE electronic sensors without adding the -S option.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10 Is Used
Precision End-Stop Tuning
Dial in the exact 15-25 mm retract distance during machine commissioning to achieve perfect positioning without adding external physical stops.
Product Size Changeovers
Quickly adjust the stroke end-position on a packaging line when switching between different product sizes, minimizing downtime and tooling changes.
Compact Assembly Stations
Utilize the 32 mm bore and short 25 mm stroke in tight spaces to deliver 402 N of pushing force while fine-tuning the clamping distance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX25-10 the Right Cylinder?
Choose this 32 mm bore cylinder when your application requires 402 N of push force at 0.5 MPa and a highly compact, adjustable travel window. If your setup demands less force, stepping down is not an option within the SAIJ range, but stepping up to a 40 mm bore yields 628 N of push force if your payload increases. The SAIJ32X25-10 is ideal when you need to vary the end-stop for different product sizes on a single machine without swapping the entire cylinder.
This cylinder uses PT tapered ports and features a 12 mm rod with an M10x1.25 thread. Because the 25 mm stroke is well below the 300 mm threshold, side-load stress is minimal, though an external guide is always recommended for heavy lateral loads. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For dimensionally interchangeable ISO 15552 replacements, match the 32 mm bore, 25 mm stroke, 10 mm adjustment, PT port, and the desired mounting hardware.

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 SAIJ32AX25-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 15-25 mm, which is set during commissioning. The adjuster is a travel stop, not a lock, and does not hold the load without continuous air pressure.
The 32 mm bore generates 402 N of push force and 345 N of pull force at 0.5 MPa operating pressure. It can reach up to 724 N of push force at 0.9 MPa, with an operating speed range of 30-800 mm/s.
