About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40
The AirTAC SAIJ32X45-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position without adding external stops. It provides a usable travel window of 5 to 45 mm, making it highly effective for applications requiring exact physical positioning during commissioning. Delivering 402 N of push force at 0.5 MPa, it fits light-duty tasks perfectly.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads for a robust pneumatic seal. The extruded aluminum barrel includes sensor grooves on both sides, supporting CMSE reed and DMSE electronic switches if a magnet is added later. It supports a compact mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40 Is Used
End-Position Tuning
Dial in the exact retract distance between 5 and 45 mm during machine commissioning without swapping cylinders.
Product Changeover
Quickly adjust the physical end-stop to accommodate different part sizes on a single production line.
Light-Duty Positioning
Utilize the 402 N push force for precise, low-impact positioning of small components and fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-40 the Right Cylinder?
Choose this 32 mm bore when a 402 N push force at 0.5 MPa is sufficient, avoiding the unnecessary bulk and higher 628 N force of a 40 mm bore. The 40 mm adjustment range on a 45 mm nominal stroke is specifically selected when you need extreme variability in the end-stop position for product changeovers, rather than relying on a fixed-stroke SAI cylinder.
Keep in mind that the rear adjuster acts purely as a mechanical travel stop and does not lock or hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. Because this is a true ISO 15552 profile cylinder, it is dimensionally interchangeable with similar ISO 15552 cylinders, matching the 32 mm bore, 45 mm stroke, PT port, and standard mounting interface.
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 SAIJ32BX45-40 FAQ
The rear adjuster screw lets you mechanically shorten the effective travel from 45 mm down to as little as 5 mm, providing a 5-45 mm usable window. It acts as a hard stop for end-position tuning, not a load lock.
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 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.
