About the Airtac SAI50 Standard Cylinder SAI50AX210
The AirTAC SAI50X210 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 210mm stroke. Because 210mm falls outside the standard stroke increments, it is supplied as a made-to-order non-standard stroke. It delivers a push force of 982 N and a pull force of 825 N at 0.5 MPa, making it well-suited for medium-duty positioning tasks.
This specific unit is configured with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It uses PT tapered port threads and lacks a magnet, meaning it cannot host internal CMSE or DMSE reed sensors without modification. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that conforms to strict ISO 15552 mounting dimensions.

Where the Airtac SAI50 Standard Cylinder SAI50AX210 Is Used
Material Diverting
Actuates diverter arms on packaging lines to route medium-weight boxes to different processing lanes.
Component Pressing
Provides the 982 N force needed to seat bearings or pins into housings without damaging surrounding material.
Vertical Lifting
Raises platform stops or lightweight product trays to specific elevations within automated storage systems.
Is the Airtac SAI50 Standard Cylinder SAI50AX210 the Right Cylinder?
Selecting this bore provides a noticeable step up from the 40mm variant, which offers 628 N of push force at 0.5 MPa, while avoiding the bulk of the 63mm bore that generates 1559 N. Because the 210mm stroke exceeds the standard 200mm increment, expect a slightly longer lead time for made-to-order production.
At 210mm of travel, the unsupported rod length is significant enough to warrant attention regarding side load. Prevent rod-bearing bending by utilizing an external guide rail or selecting a guided cylinder to handle any lateral forces. Furthermore, the standard adjustable air cushions only decelerate the piston near the end caps; they do not hold a load. If your application requires position holding without live air pressure, integrate an external pilot-operated check valve or transition to the SAIL locking variant.
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 SAI50AX210 FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder provides a push force of 982 N and a pull force of 825 N. If the pressure is increased to 0.7 MPa, the push force rises to 1374 N.
Yes, it is dimensionally interchangeable per ISO 15552 standards. You can swap it directly with other ISO 15552 profile cylinders of the same 50mm bore and 210mm stroke, provided your mounting interface matches.
