About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10
The AirTAC SAIJ32X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a 465-475 mm usable window, enabling precise end-position tuning at commissioning without swapping the cylinder or bolting on external stops. It delivers a push force of 563 N at 0.7 MPa.
This variant features a SUS304 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10 Is Used
Commissioning Fine-Tuning
Dial in the exact 465-475 mm end position during machine setup without adding physical spacers or changing the cylinder.
Product Size Changeover
Quickly adapt the retract stroke stop on a packaging line when switching to a slightly different product length.
Variable End-Stop Assembly
Provide a precise mechanical stop for pressing or locating tasks where the final position varies by a few millimeters.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10 the Right Cylinder?
Choose this 32 mm bore when your application requires the 402 N push force at 0.5 MPa; step up to the 40 mm bore if you need 628 N. An adjustable stroke is preferred over a fixed SAI cylinder when you need a variable end-stop for machine setup or product changeover. For load-holding without live pressure, use a SAIL or BSAI cylinder instead, as the SAIJ adjuster is only a stop.
This configuration matches an ISO 15552 replacement with a 32 mm bore, 475 mm stroke, 10 mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet. Because the 475 mm stroke is long relative to the 12 mm rod diameter, an external guide is recommended to prevent side-load damage.
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 SAIJ32BX475-10 FAQ
It provides a push force of 402 N at 0.5 MPa and 563 N at 0.7 MPa, with a pull force of 345 N at 0.5 MPa.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 10 mm, giving a usable travel window of 465 to 475 mm. It acts as a travel stop and does not lock the load without air pressure.
