About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-40
The AirTAC SAIJ32X650-40 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 650 mm nominal stroke that can be fine-tuned backward by up to 40 mm, yielding a usable travel window of 610 to 650 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is required later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-40 Is Used
Machine Changeover
Dial in the 610-650 mm travel window during product size transitions to set new retract endpoints without swapping hardware.
Variable End Stops
Ideal for diverter gates on conveyors where the exact 650 mm retract position must be trimmed by up to 40 mm to match varying package depths.
Commissioning Fine-Tune
Perfect for assembly stations needing micro-adjustments at setup, using the rear screw to perfect the end position without remounting the cylinder.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-40 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning during commissioning without adding external stops. If your setup needs greater thrust, stepping up to the 40 mm bore increases push force to 628 N at 0.5 MPa. Because the stroke is 650 mm, the 12 mm rod requires external guide support to prevent excessive side-loading and binding. This cylinder uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. The rear adjuster acts strictly as a travel stop, not a lock; it cannot hold a load without live air pressure. For load-holding requirements, consider an external pilot-operated check valve or the SAIL series.
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 SAIJ32BX650-40 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 650 mm down to 610 mm. This creates a 610-650 mm adjustable window for fine-tuning the retract end position during installation.
