About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40
The AirTAC SAIJ32X700-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 660-700 mm usable travel window. It delivers 402 N of push force at 0.5 MPa and operates at speeds of 30-800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threading with a G1/8 connection. The 40 mm adjustment range allows precise end-position tuning during commissioning without swapping the cylinder, while the 12 mm rod and M10x1.25 thread provide a compact interface for lighter-duty applications.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40 Is Used
End-Position Tuning
Dial in the exact retract distance within the 660-700 mm window during machine commissioning without adding external physical stops.
Product Changeover
Quickly adjust the stroke by up to 40 mm to accommodate varying package sizes on a packaging line.
Long-Stroke Assembly
Use the 700 mm travel for extended reach in assembly processes, fine-tuning the final end-stop to match part dimensions.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX700-40 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa and benefits from a 660-700 mm travel window. If your setup needs more force, stepping up to a 40 mm bore yields 628 N. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end; it does not hold the load without live air pressure. For true load-holding without continuous air, consider an AirTAC SAIL or BSAI cylinder.
Because the 700 mm stroke is long relative to the 32 mm bore, the 12 mm rod is susceptible to side loads. An external guide rail is strongly recommended to prevent rod binding and premature seal wear. This cylinder uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts.

- ✓ 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 SAIJ32BX700-40 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 700 mm down to 660 mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
