About the Airtac SAI50 Standard Cylinder SAI50BX240
The AirTAC SAI50X240 is a double-acting profile cylinder with a 50mm bore and 240mm stroke, built to the ISO 15552 mounting interface standard. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it a robust choice for medium-duty actuation. This specific unit features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads.
Because this stroke exceeds the 200mm standard interval, it is supplied as a non-standard configuration. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is added later. For high-temperature environments up to 70 C, the standard TPU seals can be swapped for Viton (H) variants.

Where the Airtac SAI50 Standard Cylinder SAI50BX240 Is Used
Packaging Equipment
Drives extended sealing jaws and film cutters where the 982 N thrust at 0.5 MPa securely creases heavy packaging materials.
Material Diverters
Actuates long-throw sorting gates on conveyor lines, utilizing the 240mm stroke to clear wide product lanes efficiently.
Pallet Handling
Pushes intermediate totes or shallow pallets into staging zones, benefiting from the SUS304 rod's resistance to humid washdown environments.
Is the Airtac SAI50 Standard Cylinder SAI50BX240 the Right Cylinder?
Selecting this 50mm bore makes sense when a 40mm cylinder (628 N at 0.5 MPa) lacks the thrust for your load, but a 63mm bore (1559 N) would be physically oversized. The 240mm stroke is ideal for applications requiring extended reach beyond standard 200mm increments.
At 240mm, the unsupported rod length is significant; always use an external guide rail or a guided cylinder to prevent side-load bending of the rod bearing. If your machinery loses air pressure, this standard cylinder cannot hold its load and will drift—use the SAIL variant with an air-released lock or an external rod lock for fail-safe positioning. Being dimensionally interchangeable per ISO 15552, it serves as a direct replacement for other ISO 15552 profile cylinders, matching the 50mm bore, 240mm stroke, G1/4 PT port, and standard FA/FB flange or TC trunnion mounts.
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 SAI50 Standard Cylinder SAI50BX240 FAQ
At 0.5 MPa, this double-acting cylinder provides a push force of 982 N and a pull force of 825 N. If you increase the operating pressure to 0.7 MPa, the push force rises to 1374 N.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders. You can swap it directly using the same 50mm bore, 240mm stroke, and G1/4 port mounting interface.
