About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30
The AirTAC SAIJ32X750-30 is a double-acting, adjustable-stroke ISO 15552 profile cylinder featuring a robust 750 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 720-750 mm usable travel window. It delivers 402N of push force and 345N of pull force at 0.5 MPa, matching the standard SAI series performance while adding rear-stop versatility.
This unit is built with 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 for flexible mounting of CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a mechanical stop to set the end position, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30 Is Used
Variable End-Stop Tuning
Dial in the exact 720-750 mm end position during machine commissioning using the rear screw, avoiding the need to swap cylinders or fabricate external stopper blocks.
Long-Travel Guiding
Ideal for extended reach operations where the 750 mm stroke requires careful alignment, pairing the cylinder with an external guide to manage side loads on the 12 mm rod.
Corrosive Environment Handling
The SUS304 stainless steel rod provides enhanced durability and corrosion resistance for extended cycle life in washdown or chemically exposed testing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-30 the Right Cylinder?
Choose this 32 mm bore when you need the 345N pull force at 0.5 MPa and have a long 750 mm travel requirement that demands exact end-position tuning during commissioning without adding external stops. If your application requires less force, stepping down is not an option in the SAIJ range, but stepping up to a 40 mm bore yields 528N of pull force for heavier loads. Because this cylinder features a 750 mm stroke, the 12 mm rod and M10x1.25 thread will experience significant leverage under side loads; an external guide bearing is strongly recommended to prevent rod binding. For applications needing true load-holding without live air, consider the SAIL or BSAI series, as this rear adjuster is not a lock. This model is dimensionally interchangeable per ISO 15552, configured with a SUS304 rod, PT ports, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ32BX750-30 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402N of push force and 345N of pull force. It operates at speeds between 30 and 800 mm/s, matching standard SAI performance.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective stroke back by up to 30 mm, creating a 720-750 mm travel window. It only sets the end position and does not lock the load without live air pressure.
