About the Airtac SAI50 Standard Cylinder SAI50X325
The AirTAC SAI50X325 is a double-acting ISO 15552 profile cylinder featuring a 50mm bore and a 325mm stroke. It generates 982N of push force and 825N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks that require substantial travel distance.
This model incorporates an extruded aluminum barrel with sensor grooves on both sides for direct mounting of CMSE or DMSE switches. The standard configuration includes a carbon steel piston rod and utilizes tapered PT G1/4 port threads to ensure a tight, reliable pneumatic connection.

Where the Airtac SAI50 Standard Cylinder SAI50X325 Is Used
Material Handling
Drives long-travel diverters and sorting gates on packaging conveyors where a 325mm stroke is required to reposition products between parallel belts.
Pallet Handling
Actuates lifting mechanisms or pusher arms for pallet positioning, utilizing the 982N push force at 0.5 MPa to shift heavy goods smoothly.
Automated Assembly
Extends tooling carriages along a 325mm path to apply components or fixtures, benefiting from the adjustable air cushions to decelerate the payload at stroke end.
Is the Airtac SAI50 Standard Cylinder SAI50X325 the Right Cylinder?
If your application requires less force, stepping down to the 40mm bore yields 628N at 0.5 MPa, while moving up to the 63mm bore provides 1559N for heavier loads. Because this 325mm stroke creates a long unsupported rod extension, it is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or select a dedicated guided cylinder.
For ISO 15552 dimensional interchangeability, match the 50mm bore, 325mm stroke, G1/4 port, and your required mounting accessory—such as an FA flange or TC trunnion. Note that this standard cylinder relies on air pressure to maintain its position; if pneumatic power is lost, the load will drift. Use an external pilot-operated check valve or the SAIL variant for fail-safe load holding.
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 SAI50X325 FAQ
At 0.5 MPa, the SAI50X325 provides a push force of 982N and a pull force of 825N. If the operating pressure is increased to 0.7 MPa, the push force rises to 1374N.
Yes, the SAI50X325 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, including those from SMC or Festo.
