Overview

The Ningbo Dimon Heavy-Duty Hydraulic Self-Closing Door Hinge combines the smooth swinging performance of a premium architectural butt hinge with the functionality of an overhead automatic door closer. Specifically engineered for interior wooden doors, flush concealed doors, hidden pantry entries, and residential corridors, this integrated hinge eliminates the need for unsightly overhead door closer arms and bulky floor springs. Featuring an internal hydraulic piston transmission system and precision needle roller bearings, it ensures silent, controlled, and cushioned self-closing action, preventing slamming while delivering up to 60 kg (132 lbs) of load capacity per pair.

Key Features

• 2-in-1 Integrated Closer & Hinge: Blends mechanical hinge aesthetics with hydraulic automatic door closing, keeping door jambs clean and modern without overhead closer boxes.
• Silent Hydraulic Cushioning & Soft-Close: Internal fluid damper automatically decelerates the swinging door in the final closing arc, gently and quietly pulling it shut without slamming.
• Needle Roller Bearing Mechanism: Heavy-duty hardened steel needle roller bearings provide exceptional axial load support, low friction resistance, and long-term sagging resistance.
• Robust 60kg (132 lbs) Load Capacity: Heavy-gauge aluminum alloy and stainless steel construction supports solid wood, engineered timber, and composite doors up to 60 kg per pair.
• Multiple Architectural Styles & Sizes:
  • Standard Mortise Butt Hinge (Flat Leaf Type C): Classic rectangular leaves for traditional routed door and jamb installations.
  • Non-Mortise / Interlocking Hinge (Type E): Flush-folding nested leaves that install without edge routing or jamb chiseling.
  • Available in 5-inch (approx. 125mm) and 6-inch (approx. 150mm) configurations.
• Contemporary Finish Options: Available in Electrostatic Matte Black, Satin Silver, and Gunmetal Gray with matching end caps and mounting hardware.
