About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75S
The AirTAC SAIJ32X750-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 675-750 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it utilizes a 12 mm carbon steel rod with an M10x1.25 thread and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors for precise end-of-travel detection. The SUS304 stainless steel rod material provides excellent corrosion resistance for harsh or washdown environments. The rear adjustment screw allows you to fine-tune the retract end position during commissioning without adding external stops or swapping the cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75S Is Used
Product Changeover Positioning
Dial in the 675-750 mm retract end-stop during line changeovers to accommodate different product lengths without physically swapping the actuator.
Variable End-Stop Diverting
Fine-tune the diverting stroke on a packaging conveyor to adjust reject distances on the fly while maintaining a compact 32 mm ISO 15552 footprint.
Sensitive Tool Commissioning
Gradually extend the travel window during machine setup to prevent tooling crashes, allowing precise mechanical tuning of the 750 mm stroke.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-75S the Right Cylinder?
Choose this 32 mm bore when you need 402 N push force at 0.5 MPa and a highly adjustable end position; step down if your force requirements are minimal, or up to the 40 mm bore (628 N push) for heavier loads. The 75 mm adjustment range is ideal for product changeovers on a line where exact end positions vary slightly between runs. Because the stroke is 750 mm, an external guide rail is strongly recommended to prevent excessive side-load wear on the 12 mm rod and seals.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air pressure. For dead-load holding, consider the SAIL pneumatic lock or BSAI clamp-lock series instead.

- ✓ 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 SAIJ32BX750-75S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. The maximum operating pressure is 1.0 MPa, yielding up to 82 kgf. The operational speed range for this 32 mm bore is 30-800 mm/s.
The rear adjuster screw lets you shorten the 750 mm nominal stroke by up to 75 mm, creating a 675-750 mm usable travel window. It functions purely as a mechanical stop to set the retract end position and does not lock or hold the load without continuous air pressure.
