About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-75S
The AirTAC SAIJ32X650-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 575-650 mm usable travel window, letting you dial back the nominal 650 mm stroke by up to 75 mm during machine commissioning without adding external stops. It delivers 402 N of push force at 0.5 MPa and includes a SUS304 stainless steel rod for superior corrosion resistance.
Equipped with a magnet for position sensing, this unit supports AirTAC CMSE reed and DMSE electronic solid-state switches seated in the dual-side sensor grooves of the extruded aluminum barrel. The rear adjustment screw acts purely as a travel stop to set end positions; it does not lock the load pneumatically. For applications requiring position holding without live air pressure, an external rod lock or pilot-operated check valve is necessary.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-75S Is Used
Machine Setup & Changeover
Fine-tune the 575-650 mm travel window during product size changeovers to set precise end-stops without physically swapping out the entire cylinder.
Variable End-Stop Positioning
Adjust the rear stopper on the fly to alter the extension reach of a diverter or pusher arm by up to 75 mm to handle different package lengths.
Long-Stroke Sensing
Leverage the -S magnet with DMSE electronic sensors to track the full 650 mm travel, ensuring accurate positioning of long-actuation tooling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX650-75S the Right Cylinder?
Choose this 32 mm bore when your application requires a maximum 82 kgf output at 1.0 MPa and a long 650 mm stroke. If your changeover needs less travel, the rear adjuster fine-tunes the end position by up to 75 mm, saving you from swapping cylinders. If you need higher force, step up to the 40 mm bore, which provides 628 N of push force at 0.5 MPa. Because the stroke is 650 mm, an external guide is highly recommended to prevent side-load damage to the rod.
To match this exact configuration for an ISO 15552 dimensional replacement, specify the 32 mm bore, 650 mm stroke, 75 mm adjustment range, PT tapered port threads, and the -S magnet option. The mounting interface accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. For fixed-stroke needs without the adjuster, consider the standard SAI 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 SAIJ32BX650-75S 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. At the maximum rated pressure of 1.0 MPa, it delivers a maximum output of 82 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from 650 mm down to as little as 575 mm. This adjuster sets the travel end and deceleration point but does not function as a lock to hold the load without live air pressure.
