About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10
The AirTAC SAIJ32X40-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 40mm stroke that can be fine-tuned down by 10mm, giving an effective 30-40mm travel window for precise positioning. In the 32mm bore class, it delivers 402N of push force at 0.5MPa and utilizes a PT tapered port thread.
This adjustable variant uses an SUS420J2 stainless steel piston rod to resist corrosion while handling side loads better than thinner alternatives. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed or DMSE solid-state switches if position feedback is added later. The rear adjuster acts purely as a mechanical stop to set the travel end and cannot hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10 Is Used
End-Stop Tuning
Dial in the exact 30-40mm travel distance during machine commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the retract position on packaging lines when handling slightly different product sizes.
Light Assembly
Provides 402N of push force at 0.5MPa for precise pressing and light-duty assembly tasks.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX40-10 the Right Cylinder?
Select this 32mm bore cylinder when an application requires 402N of push force at 0.5MPa and a variable end-stop for product changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. If the setup requires slightly less force and a smaller footprint, stepping down is possible, but stepping up to a 40mm bore provides 628N at 0.5MPa for heavier tooling.
Because the stroke is short, side loading is minimal, but the rear adjuster is strictly a travel stop, not a lock. For dead-end load holding without continuous air pressure, consider an external pilot-operated check valve or the SAIL locking cylinder. As a direct ISO 15552 interchangeable replacement, specify the 32mm bore, 40mm stroke, 10mm adjustment, PT port, and Basic mounting setup.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ32AX40-10 FAQ
It features a rear adjusting screw that allows you to shorten the effective travel from its nominal 40mm down to 30mm, creating a 10mm setup window. This stopper sets the end position but does not lock the load without continuous air pressure.
At a standard 0.5MPa operating pressure, the SAIJ32X40-10 provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9MPa.
