The SI63BX275S industrial-grade cylinder features a heavy-duty construction with dual anti-rotation guides, optimized for high-cycle applications requiring precise linear motion. Its wear-resistant rod seal system and integrated shock absorption make it ideal for applications with sudden load changes. Requires 5-40μm filtered compressed air with ISO VG32 lubricant (optional oil-free operation).
- Automated assembly line clamping mechanisms
- Die-casting machine ejection systems
- Palletizing robot arm actuators
- Plastic injection molding machine gates
- Heavy-duty material handling conveyors
Installation notes:
- Allow 15mm minimum clearance around cylinder body for heat dissipation
- Align piston rod within 0.5° angular misalignment tolerance
- Lubricate guide rods every 500km of cumulative travel
