About the Airtac SAI50 Standard Cylinder SAI50BX210
The AirTAC SAI50X210 is a double-acting ISO 15552 profile cylinder engineered to deliver 982 N of push force at 0.5 MPa. Its 210 mm stroke provides the extended travel needed for mid-range material handling and packaging tasks. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that simplifies cleaning and sensor placement.
This specific configuration utilizes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in washdown or chemically exposed environments. It features PT tapered port threads and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not supported without modification.

Where the Airtac SAI50 Standard Cylinder SAI50BX210 Is Used
Packaging Diverters
Actuates routing gates on packaging lines where the 982 N force easily pushes heavy cartons into secondary processing lanes.
Product Reject Arms
Deploys a mechanical arm to knock defective items off a conveyor belt during high-speed quality control inspections.
Clamp Fixtures
Secures wooden or composite workpieces in light assembly jigs, utilizing the 210 mm stroke to accommodate varying part widths.
Is the Airtac SAI50 Standard Cylinder SAI50BX210 the Right Cylinder?
Selecting this 50 mm bore makes sense when a 40 mm bore (providing 628 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N) would be physically oversized. Because the 210 mm stroke exceeds 300 mm is false here, side-load bending is less severe than on exceptionally long units, though external guides should still be used for heavy off-center loads.
As a standard double-acting cylinder, it relies on continuous air pressure to maintain its rod position; if air is exhausted or removed, the piston will drift. For applications requiring dead-stop holding under zero pressure, specify the SAIL variant with an air-released lock or the BSAI clamp-lock version. To match existing mounting footprints, pair this unit with FA or FB flanges, LB foot brackets, or TC trunnion joints.
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 SAI50BX210 FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder provides 982 N of push force and 825 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, the SAI50X210 is dimensionally interchangeable per ISO 15552 standards. You can use it as a direct replacement for other ISO 15552 profile cylinders with matching 50 mm bore and 210 mm stroke dimensions, utilizing standard PT G1/4 ports.
