About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10S
The AirTAC SAIJ32X475-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 465 to 475 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops. In the 32 mm bore class, it delivers 402 N of push force at 0.5 MPa and utilizes a G1/8 port.
This variant incorporates a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10S Is Used
Machine Commissioning
Dial in the exact 465-475 mm end stop during setup to perfect product seating without swapping cylinders.
Product Changeover
Quickly adapt the retract position on a packaging line when handling slightly different carton sizes.
End-Stop Tuning
Fine-tune the stroke by up to 10 mm to compensate for mechanical wear or slight misalignment over time.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX475-10S the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, stepping down from a 40 mm bore (628 N) to save space, or up if higher force is required. The 10 mm adjustable stroke is ideal for product changeovers where a fixed SAI cylinder would require shimming. Remember, the rear adjuster is a travel stop, not a lock; it cannot hold loads without live air. For load-holding, consider SAIL or BSAI.
At 475 mm, this stroke is well within the 1000 mm maximum for this bore, but the long unsupported travel necessitates an external guide to prevent rod side-loading. To match this ISO 15552 cylinder, specify a 32 mm bore, 475 mm stroke, 10 mm adjustment, PT tapered port, and the -S magnet option.
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 SAIJ32BX475-10S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. At 0.7 MPa the push force increases to 563 N.
The rear adjuster acts as a mechanical stop, letting you shorten the 475 mm nominal stroke by up to 10 mm, creating a 465-475 mm travel window. It decelerates travel but does not lock the load.
