About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-20
The AirTAC SAIJ32X750-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 730-750 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it utilizes a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a secure pneumatic seal.
Because the stroke extends to 750 mm on a 12 mm rod, external guiding is recommended to manage deflection and side loads. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to add CMSE reed or DMSE electronic switches if position feedback is later required.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-20 Is Used
End-Position Tuning
Dial in the exact retract distance within the 730-750 mm window during machine commissioning without adding external stopper blocks.
Product Changeover
Quickly adjust the stroke by up to 20 mm on a packaging line when handling slightly different package lengths.
Long-Travel Diverting
Use the 750 mm stroke to push items across a wide conveyor, relying on the adjuster to fine-tune the resting position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX750-20 the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning without swapping cylinders, providing 402 N push and 345 N pull at 0.5 MPa. If your setup needs greater thrust, stepping up to the 40 mm bore yields 628 N push force. The rear adjuster acts strictly as a travel stop for commissioning and product changeovers; it is not a locking device. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead. As a dimensionally interchangeable ISO 15552 unit, ensure your replacement matches the 32 mm bore, 750 mm stroke, 20 mm adjustment, PT port, and Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting set.
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 SAIJ32BX750-20 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 750 mm down to 730 mm. This creates a 730-750 mm adjustable window for fine-tuning the end position at commissioning without replacing the cylinder.
