About the Airtac SAI50 Standard Cylinder SAI50X425
The AirTAC SAI50X425 is a double-acting ISO 15552 profile cylinder engineered to deliver 982N of push force at 0.5MPa. Its 425mm stroke is optimal for mid-range linear actuation tasks requiring substantial travel. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists contamination.
Built for versatility, this model features a standard carbon steel piston rod. The barrel incorporates dual sensor grooves allowing for direct mounting of CMSE or DMSE switches when a magnet is specified. It operates smoothly at speeds between 30 and 800mm/s, making it a robust choice for dynamic automation environments.

Where the Airtac SAI50 Standard Cylinder SAI50X425 Is Used
Package Diversion
Ideal for actuating diverter arms on packaging lines, utilizing the 425mm stroke to push cartons smoothly onto secondary chutes.
Component Pressing
Provides reliable clamping force for light-duty pressing and seating operations in automated assembly machinery.
Material Handling
Drives lifting and pushing mechanisms in end-of-line palletizing cells where mid-range force and travel are required.
Is the Airtac SAI50 Standard Cylinder SAI50X425 the Right Cylinder?
Select this 50mm bore when an application requires more thrust than the 40mm bore (628N at 0.5MPa) but lacks the space or pneumatic capacity for a 63mm model. The 425mm stroke is a standard configuration, falling well within the 1200mm maximum limit for this bore size.
Because the stroke is 425mm, the unsupported rod length introduces a risk of bending under heavy side loads. To mitigate premature rod-bearing wear, implement an external guide rail or utilize a guided cylinder mechanism. Note that standard air cushions only decelerate the piston near stroke ends; they will not hold a load if air pressure is lost. For position holding without live pressure, consider the SAIL variant with an air-released lock or an external rod lock.
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.
