About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-50
The AirTAC SAIJ32X650-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 600-650mm usable travel window. Delivering 402N of push force at 0.5MPa, it is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel includes sensor grooves on both sides.
This adjustable-stroke design allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The 50mm adjustment screw acts purely as a mechanical travel stop to set deceleration, not as a lock to hold the load without live air. For position holding, an external rod lock or SAIL cylinder is required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-50 Is Used
Machine Setup and Changeover
Dial in the exact retract distance between product runs by adjusting the rear stopper up to 50mm, avoiding the need to physically swap cylinders when tolerances shift.
Variable End-Stop Positioning
Provides a 600-650mm travel window on a long-stroke conveyor sorting arm, allowing operators to fine-tune the retracted resting position during initial commissioning.
Corrosive Environment Testing
The SUS304 stainless steel rod withstands moisture and mild chemicals in environmental test chambers while maintaining ISO 15552 mounting interchangeability.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-50 the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning for a 650mm stroke application. If your process requires higher force, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. The SAIJ32X650-50 configuration includes a PT port thread, SUS304 (code B) rod material, and no magnet, meaning it is not compatible with CMSE or DMSE sensors without modification. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 650mm stroke is long relative to the 12mm rod diameter, an external guide is strongly recommended to prevent excessive side-load damage. The rear adjuster is a stop, not a brake; if the machine loses air pressure, this cylinder will not hold its load. Use a pilot-operated check valve or a BSAI clamp-lock cylinder for fail-safe load holding.

- ✓ 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 SAIJ32BX650-50 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At the maximum 1.0MPa pressure, it delivers up to 82kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 50mm, creating a usable travel window of 600-650mm. This stopper sets the end position but does not lock or hold the load without continuous air pressure.
