The AirTAC Adjustable Cylinder SAIJ32 SAIJ32AX225-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 225mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
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.
It uses a PT tapered G1/8 port and variable air cushions at both ends to regulate impact deceleration.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Dial in the exact 175-225mm travel window during product size changes without physically swapping cylinders or repositioning hard stops.
Fine-tune the retract end-position during commissioning to perfect seating or clamping forces on delicate workpieces.
Adjust the effective travel on a sorting diverter to handle different package sizes on the fly.
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
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.
