About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50
The AirTAC SAIJ32X750-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 700-750mm usable travel window, allowing you to dial back the effective stroke by up to 50mm during commissioning. With a 32mm bore, it delivers 402N of push force at 0.5MPa and uses a PT G1/8 port.
This model incorporates an SUS420J2 stainless steel rod for enhanced corrosion resistance and includes variable air cushions at both ends. The extruded aluminum barrel features sensor grooves on both sides, ready for CMSE reed or DMSE electronic sensors if a magnet is added later. The rear adjuster acts purely as a travel stop, meaning it will not hold a load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50 Is Used
Machine Changeover
Dial in the 700-750mm travel window during product size transitions without adding external mechanical stops.
End-Position Tuning
Fine-tune the retract end position at commissioning to perfectly align a 402N push assembly.
Adjustable Diverter
Set variable retract stops for a conveyor routing gate that handles multiple package lengths.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-50 the Right Cylinder?
Choose this 32mm bore adjustable cylinder when an application requires precise end-position tuning without swapping out physical components. If you need greater thrust, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. The 50mm adjustment range is excellent for accommodating product size changes on a line. Because the 750mm stroke is long, an external guide is recommended to prevent excessive side-loading on the 12mm rod. For load-holding without live pressure, consider a SAIL or BSAI cylinder instead. This unit is dimensionally interchangeable with ISO 15552 cylinders and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAIJ32AX750-50 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 82 kgf.
The rear adjusting screw acts as a mechanical stop that shortens the 750mm nominal stroke by up to 50mm, creating a 700-750mm usable travel window. It only sets the travel end and does not lock or hold the load without continuous air pressure.
