- Packaging machinery ejection mechanisms
- Plastic injection mold clamping units
- Material handling conveyor diverters
- Textile machinery tension control
Installation guidelines:
For strokes >500mm, use center-supported mounting to prevent rod sagging.
Maintain 0.5-1mm/kg alignment tolerance. Lubricate through air port using
3-5 drops of oil per 1m³ of compressed air.
