About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-10
The AirTAC SAIJ32X650-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 640-650 mm. It delivers 402 N of push force and 345 N of pull force at a 0.5 MPa operating pressure, making it suitable for light-duty positioning tasks.
This variant incorporates a SUS304 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches, while the rear stopper allows fine end-position tuning without adding external physical stops.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-10 Is Used
Machine Changeover
Dial in the 640-650 mm retract position during product size changes without physically swapping cylinders or repositioning external hard stops.
Light-Duty Diverting
Provides 402 N of push force at 0.5 MPa for moving small packages, with the 10 mm adjustment screw allowing exact tuning of the diverting endpoint.
End-Position Calibration
Fine-tune the retract stop during commissioning to compensate for mechanical wear or sensor bracket drift over a long 650 mm stroke.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-10 the Right Cylinder?
Select this 32 mm bore when an application requires precise end-stop calibration over a 640-650 mm travel range, stepping down from a 40 mm bore which provides 628 N push force at 0.5 MPa. The 10 mm rear adjuster screw is ideal for product changeovers, allowing you to dial in the exact retract position without swapping the cylinder. Because the nominal stroke is 650 mm, an external guide is highly recommended to prevent side-load damage to the 12 mm rod and M10x1.25 thread.
For ISO 15552 replacement matching, verify the 32 mm bore, 650 mm stroke, 10 mm adjustment range, PT G1/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. This cylinder does not hold loads without live air pressure, as the adjuster is a travel stop rather than a lock; for dead-air load holding, consider the SAIL or BSAI 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 SAIJ32BX650-10 FAQ
At a 0.5 MPa operating pressure, this 32 mm bore double-acting cylinder provides 402 N of push force and 345 N of pull force. The maximum thrust is 82 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the effective travel from 650 mm down to 640 mm. It sets the retract end position but does not lock or hold the load without continuous air pressure.
