About the Airtac SAI50 Standard Cylinder SAI50X500
The AirTAC SAI50X500 is a double-acting profile cylinder with a 50mm bore and 500mm stroke, fully compliant with the ISO 15552 standard. It delivers a push force of 982 N at 0.5 MPa, making it well-suited for medium-duty linear actuation tasks requiring extended travel distances.
This model features a robust carbon steel piston rod and utilizes PT tapered port threads for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches when position feedback is required.

Where the Airtac SAI50 Standard Cylinder SAI50X500 Is Used
Material Transfer
Drives extended push-off arms on conveyor lines to sort or divert packages over a 500mm travel distance.
Assembly Press
Provides consistent 982N pressing force at 0.5 MPa for seating bearings or pins into housings.
Pallet Handling
Actuates lifting and positioning mechanisms for palletizing operations requiring long linear displacement.
Is the Airtac SAI50 Standard Cylinder SAI50X500 the Right Cylinder?
Selecting this 50mm bore is ideal when you need more thrust than the 40mm bore (which provides 628 N at 0.5 MPa) but want a smaller footprint than the 63mm option (1559 N at 0.5 MPa). At 500mm of travel, the unsupported rod length is substantial; side loads can cause rod-bearing bending and premature wear. To manage this, use an external guide rail or select a guided cylinder to prevent mechanical deflection.
As a true ISO 15552 profile cylinder, it serves as a direct replacement for other ISO 15552 cylinders, matching the exact mounting interface dimensions for foot, flange, and trunnion accessories. Note that the adjustable air cushions only decelerate the piston near stroke ends; if the application must hold a load without live air pressure, integrate an external rod lock or 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 SAI50X500 FAQ
