A high-rigidity compact cylinder featuring wear-resistant rod guides and precision honed tubing. The dual-cushion design minimizes end-impact noise while maintaining positioning accuracy (±0.5mm repeatability). Includes magnetic piston version option (SI63X70SCA-M9L) for position sensing.

Typical Applications:

• Clamping fixtures in CNC machining centers
• Material handling gates in conveyor systems
• Packaging machine lid open/close mechanisms
• Textile machinery thread tension control
• Automated door locking systems

Installation notes:

• Allow 5mm minimum clearance for magnetic sensor installation
• Use M6 mounting screws with 12mm engagement depth (torque 8.8N·m)
• For vertical mounting, position port "A" downward to prevent condensate accumulation

Lubrication requirement: While pre-lubricated, add 1-2 drops of ISO VG32 turbine oil every 500,000 cycles in high-usage (>5Hz) applications. Avoid petroleum-based lubricants that degrade NBR seals.
