About the Airtac SAI50 Standard Cylinder SAI50X275S
The AirTAC SAI50X275-S is a double-acting ISO 15552 profile cylinder engineered to deliver 982N of push force and 825N of pull force at 0.5 MPa. Its 275mm stroke provides the extended travel needed for mid-range material handling and automated positioning tasks. As a genuine AirTAC component, it ensures dimensional interchangeability for direct replacements.
This specific configuration includes a standard carbon steel piston rod for high tensile strength under dynamic loads. The -S suffix indicates an integrated magnet, allowing seamless operation with CMSE or DMSE reed switches housed in the dual sensor grooves machined into the extruded aluminum barrel. Fluid compatibility is limited to filtered air.

Where the Airtac SAI50 Standard Cylinder SAI50X275S Is Used
Package Diverting
Actuates routing gates on 50mm belt conveyors to sort medium-weight parcels, utilizing the 275mm stroke to clear the product path fully.
Clamp Actuation
Drives vertical clamping arms in light CNC fixturing, providing 825N of pull force to secure aluminum housings during machining.
Pallet Lifting
Raises lower-tier product trays in automated storage systems, relying on the integrated magnet for precise height confirmation via DMSE sensors.
Is the Airtac SAI50 Standard Cylinder SAI50X275S the Right Cylinder?
Selecting this 50mm bore over the smaller 40mm variant upgrades your thrust from 628N to 982N at 0.5 MPa, while stepping up to the 63mm bore yields 1559N if your application demands heavier payload movement. Because the 275mm stroke exceeds 300mm, it approaches the threshold where side loading can accelerate rod-bearing wear; utilizing an external guide mechanism or a guided cylinder carriage is recommended to prevent rod deflection.
This model features PT tapered port threads and a G1/4 connection. For installations requiring fail-safe load holding upon air pressure loss, note that the standard adjustable air cushions only decelerate the piston at stroke ends and do not act as a brake. In such scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
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 SAI50X275S FAQ
At a 0.5 MPa operating pressure, this 50mm bore cylinder generates 982N of push force and 825N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 1374N.
Yes, the SAI50X275-S is built to the ISO 15552 standard, making its mounting dimensions fully interchangeable with other ISO 15552 profile cylinders of the same bore and stroke.
