About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-40
The AirTAC SAIJ32X600-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 560-600 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it utilizes a 12 mm SUS420J2 stainless steel rod and a PT G1/8 port. This combination of a corrosion-resistant rod and a fine-tunable end-stop is ideal for equipment requiring precise positioning.
Unlike a fixed-stroke SAI cylinder, this model allows you to dial in the exact retract position at commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for CMSE or DMSE switches. Remember that the rear adjuster acts only as a travel stop for deceleration and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-40 Is Used
Machine Changeover
Dial in the 560-600 mm retract position during product size changes without swapping the cylinder or adding external stoppers.
End-Position Tuning
Fine-tune the exact end-of-stroke point at commissioning to absorb mechanical tolerances and achieve precise positioning.
Variable End Stops
Adjust the travel window on packaging lines to handle varying product lengths on the same conveyor setup.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX600-40 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa and a highly adjustable end-position. If your application requires less force, stepping down to a 25 mm bore offers a smaller footprint, while stepping up to a 40 mm bore provides 628 N of push force for heavier loads. The SAIJ32X600-40 is selected specifically for its 40 mm adjustment range, which allows a 560-600 mm travel window to accommodate product changeovers or fine-tune machine setup.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 600 mm stroke, PT G1/8 port, and SUS420J2 rod material. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke is 600 mm, the long unsupported travel requires an external guide to prevent excessive side-load wear on the rod. For load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead of relying on the adjuster.

- ✓ 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 SAIJ32AX600-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the 600 mm nominal stroke by up to 40 mm, creating a 560-600 mm usable travel window. It functions as a travel stop for deceleration and does not lock or hold the load without live air pressure.
