About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50
The AirTAC SAIJ32X225-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 50mm of travel reduction. This creates a usable stroke window of 175-225mm, enabling precise end-position tuning at commissioning without swapping out the physical cylinder. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch placement.
Delivering 402N of push force and 345N of pull force at 0.5MPa, this 32mm bore unit is equipped with a SUS420J2 stainless steel rod for enhanced durability against environmental wear. It uses a PT tapered G1/8 port and variable air cushions at both ends to regulate impact deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50 Is Used
Machine Changeover
Dial in the exact 175-225mm travel window during product size changes without physically swapping cylinders or repositioning hard stops.
End-Stop Calibration
Fine-tune the retract end-position during commissioning to perfect seating or clamping forces on delicate workpieces.
Variable Sorting Stroke
Adjust the effective travel on a sorting diverter to handle different package sizes on the fly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX225-50 the Right Cylinder?
Choose this 32mm bore model when an application requires 402N of thrust at 0.5MPa and exact end-stop variability; if your process needs less force, stepping down is not an option from this bore size, but stepping up to a 40mm bore yields 628N. The 50mm adjustment range is ideal for product changeovers on a line, allowing operators to dial in the exact 175-225mm travel without adding external mechanical stops.
For ISO 15552 replacement matching, verify the 32mm bore, 225mm stroke, 50mm adjustment, PT G1/8 port, and basic mounting setup. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for load-holding requirements, consider an SAIL or BSAI cylinder. Since the stroke is 225mm, ensure external guides are used to manage side-load stresses on the 12mm rod.
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 SAIJ32AX225-50 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach up to 724N of push force at 0.9MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm from the nominal 225mm, providing a usable travel window of 175-225mm for fine-tuning the end position without replacing the cylinder.
