About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30
The AirTAC SAIJ32X475-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 445-475mm usable travel window, allowing you to dial back the 475mm nominal stroke by up to 30mm during commissioning. Delivering 402N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS304 stainless steel rod (option B) for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is specified without a magnet. The rear stopper solely sets the travel end-point and does not function as a load lock.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30 Is Used
Machine Changeover
Dial in the 445-475mm travel window rapidly when switching a packaging line to a different product size, avoiding the need to physically swap cylinders.
End-Position Tuning
Fine-tune the retraction point at commissioning to perfectly align a 402N pick-and-place operation without adding bulky external stopper blocks.
Light Diverting
Actuate a lightweight routing gate on a conveyor, using the rear screw to adjust the actuation angle precisely for varying package profiles.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-30 the Right Cylinder?
Choose this 32mm bore when your application requires the 402N push force at 0.5 MPa alongside precise end-position tuning. If your setup demands greater thrust, stepping up to the 40mm bore yields 628N. The adjustable stroke is ideal for product changeovers, whereas a fixed SAI cylinder is better for rigid, unchanging endpoints. To match this exact configuration for an ISO 15552 replacement, specify the 32mm bore, 475mm stroke, 30mm adjustment, PT tapered port, SUS304 rod, and no magnet.
Because the 475mm stroke is relatively long for a 32mm bore, the M10x1.25 rod and thread are susceptible to side-loading. An external guide mechanism is highly recommended to prevent premature seal wear. For applications requiring the cylinder to hold its position without continuous live air pressure, note that this adjuster is strictly a travel stop; you should explore an external rod lock or the SAIL series instead.
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 SAIJ32BX475-30 FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 475mm nominal stroke down to a minimum of 445mm. It only limits the travel end and does not lock the load without live air.
