Where the Airtac SAI63 Standard Cylinder SAI63X400 Is Used
Material Handling
Ideal for pushing or diverting packages on conveyor lines where a 400mm stroke and 1559 N of force are required.
Machine Clamping
Provides reliable clamping pressure for medium-weight workpieces during machining or assembly processes.
Automated Assembly
Drives linear movements in automated assembly stations, benefiting from the standardized ISO 15552 mounting interface.
Is the Airtac SAI63 Standard Cylinder SAI63X400 the Right Cylinder?
At 0.5 MPa, this 63mm bore cylinder provides 1559 N of push force. If your application requires less force, stepping down to the 50mm bore yields 982 N, while moving up to the 80mm bore provides 2513 N.
Because the stroke is 400mm, the unsupported rod length is substantial. To prevent rod-bearing bending and premature seal wear under side loads, implement an external guide rail or select a guided cylinder. Note that the adjustable air cushions only decelerate the piston at stroke ends; they do not hold the load. If position holding upon air loss is required, consider the SAIL variant with an air-released lock. For a drop-in replacement, match the 63mm bore, 400mm stroke, G3/8 port, and mounting accessory.
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.
