Component Specifications

Definition
The Hinge Leaf (Door Side) is a critical component of hinge assemblies used in industrial machinery, equipment enclosures, and access panels. It is specifically designed to mount on the moving door or panel, connecting to the stationary hinge leaf via a pin or bearing system to enable controlled rotational movement. This component must withstand operational loads, maintain alignment, and provide smooth motion throughout its service life while resisting wear, corrosion, and mechanical stress.
Working Principle
The door-side hinge leaf operates on the principle of rotational kinematics, where it pivots around a central axis (hinge pin) to allow angular displacement of the attached door or panel. It transfers loads from the door to the hinge assembly while maintaining geometric constraints that ensure proper alignment and prevent lateral movement. The leaf's geometry and mounting points create a moment arm that determines torque requirements and motion characteristics.
Materials
Typically manufactured from cold-rolled steel (ASTM A366), stainless steel (AISI 304/316 for corrosion resistance), or aluminum alloys (6061-T6 for lightweight applications). Surface treatments include zinc plating, powder coating, or anodizing for enhanced durability and corrosion protection.
Technical Parameters
  • Width 25-100 mm
  • Length 50-300 mm
  • Thickness 2.0-6.0 mm
  • Hole Pattern 3-5 mounting holes (Ø4-8 mm)
  • Load Capacity 50-500 kg (depending on size/material)
  • Operating Temperature -40°C to +120°C
  • Pin Diameter Compatibility Ø6-12 mm
Standards
ISO 9001, DIN 7952, ISO 2768-mK

Frequently Asked Questions

What is the primary function of the hinge leaf on the door side?

It provides the mounting interface for the moving door/panel, transfers operational loads to the hinge assembly, and enables controlled rotational movement around the hinge pin axis.

How do I select the right material for a hinge leaf in corrosive environments?

Use stainless steel (AISI 316) or aluminum with anodized coating for high corrosion resistance. Consider powder coating on steel for additional protection in moderate environments.

What standards ensure hinge leaf interchangeability?

DIN 7952 specifies dimensional standards for hinge leaves, while ISO 9001 ensures quality management in manufacturing for consistent compatibility.

Can I contact factories directly?
