About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30S
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 nominal 475 mm travel by up to 30 mm for a precise 445-475 mm usable window. It delivers 402 N of push force at 0.5 MPa and operates at speeds between 30 and 800 mm/s. The integrated -S magnet supports position sensing via CMSE reed or DMSE electronic switches fitted into the dual-side sensor grooves.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops; it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30S Is Used
Machine Changeover
Quickly fine-tune the 445-475 mm retract end-stop during product size changeovers without swapping the actuator or bolting on external physical stops.
Variable End Positioning
Dial in the exact end-of-stroke position during commissioning to accommodate sensor placement or mechanical tolerances in assembly tooling.
Diversion Gate Setup
Adjust the travel window on a conveyor sorting gate to handle varying package sizes, ensuring precise physical contact without reprogramming.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning on a long-stroke actuator, stepping up from smaller variants if you need slightly higher thrust, or down to a 40 mm bore (628 N push at 0.5 MPa) if your load demands more force. The adjustable stroke is ideal for machine setups requiring variable end stops or product changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. To replace this cylinder, match the 32 mm bore, 475 mm stroke, 30 mm adjustment, PT port, and -S magnet.
Because the 475 mm stroke is relatively long for a 32 mm bore, the 12 mm rod should be guided externally to prevent excessive side-loading and premature seal wear. For applications requiring the load to be held in place without continuous air pressure, note that this adjuster is not a brake; you should explore an AirTAC SAIL locking cylinder or an external pilot-operated check valve instead.

- ✓ 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 SAIJ32BX475-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 30 mm, creating a 445-475 mm travel window. It functions as a mechanical stop for end-position tuning and is not a lock.
