About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30S
The AirTAC SAIJ32X475-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 475mm nominal stroke by up to 30mm. This creates a precise 445-475mm usable travel window, enabling exact end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers 402N of push force at 0.5 MPa and features an integrated magnet for position sensing.
This unit is built with a SUS420J2 stainless steel piston rod for enhanced durability against moisture and light corrosion. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a mechanical travel stop to set the retract end, while the standard adjustable air cushions handle deceleration; neither component will hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30S Is Used
Machine Changeover
Dial in the 445-475mm travel window during product size changes without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke by up to 30mm at commissioning to perfect the seating of a 402N push force assembly.
Variable End Stops
Adjust the rear mechanical stop on the fly to alter the reject pusher distance on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-30S the Right Cylinder?
Choose this 32mm bore adjustable cylinder when your setup requires a 445-475mm stroke window and exact end-positioning during product changeovers, rather than a fixed-stroke SAI model. If your application needs greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. Because the stroke is 475mm, the 12mm diameter rod and M10x1.25 thread are susceptible to side-loading; always guide the load externally to prevent rod binding. For load-holding without live air, select a SAIL or BSAI cylinder instead. To match this ISO 15552 footprint, specify: 32mm bore, 475mm stroke, 30mm adjustment, PT tapered ports, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet.

- ✓ 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 SAIJ32AX475-30S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the 475mm nominal stroke by up to 30mm, providing a usable travel window of 445-475mm. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without continuous air pressure.
