Corrosion-resistant anodized surface treatment enables operation in humid environments. Optional auto switch models (D-M9N/D-A9N) available for feedback control.
- Heavy-duty press machines (metal stamping/die casting)
- Automotive assembly line clamping fixtures
- Plastic injection molding ejectors
- Paper roll handling systems
- Shipbuilding welding positioners
Installation guidelines:
Use locknuts with 35-45 N·m torque for mounting. Maintain 0.5mm minimum alignment tolerance between rod and load. For vertical installations, add counterbalance valves. Lubricate through air supply (ISO VG32 oil mist) if operated in high-cycle (>500CPM) applications.
