About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-30S
The AirTAC SAIJ32X40-30-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, featuring a SUS420J2 stainless steel rod and a position-sensing magnet for CMSE or DMSE switches. Its 30 mm adjustment screw lets you trim the 40 mm nominal stroke back, providing a 10 to 40 mm usable travel window for exact end-position tuning without swapping hardware.
Delivering 345 N pull force at 0.5 MPa, this 32 mm bore unit uses PT tapered ports and variable air cushions at both ends. The rear stopper sets the travel end, but it does not hold the load without live air pressure; for fail-safe holding, use a SAIL or BSAI series cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-30S Is Used
Machine Changeover
Dial in the 10-40 mm stroke window instantly when fitting a new product size on the line, avoiding physical cylinder swaps.
End-Position Tuning
Fine-tune the retract stop during commissioning to perfect the tooling approach without adding external mechanical stops.
Precision Assembly
Use the variable end-stop to softly seat parts with the 345 N pull force, adjusting the travel limit to match component tolerances.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-30S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need on-the-fly end-stop tuning for product changeovers. If your process needs less force, the 32 mm bore is a solid baseline; stepping up to a 40 mm bore yields 528 N pull at 0.5 MPa. For load-holding without continuous air, select SAIL or BSAI types, as this adjuster is strictly a travel stop.
This SKU includes a magnet for CMSE reed and DMSE electronic sensors. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on other profiles.

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 SAIJ32AX40-30S FAQ
It has a 40 mm nominal stroke with a 30 mm rear adjuster, creating a 10 to 40 mm usable travel window that you can fine-tune at commissioning.
At 0.5 MPa it provides 402 N push force and 345 N pull force. The rear adjuster acts as a travel stop and does not lock or hold the load without live air.
