Key Components of Industrial Hinges and Their Functions

The standard hinge consists of several core components that work in tandem to ensure smooth operation, reliable load-bearing capacity, and seamless movement. Each part is essential to the overall performance and functionality of the hinge:

1. Leaf (Blade)

The blade is the main metal plate of the hinge and is connected by screws or welding. It distributes the load and ensures stability. The TANJA blade is made of high-strength steel or stainless steel and is securely installed in heavy industrial doors through precise holes.

2. Knuckle (Bearing Sleeve)

The knuckle are the cylindrical interlocking parts at the edges of each leaf. The opposite finger joints are aligned, forming a barrel that holds the hinge pin, allowing rotation while maintaining the connection of the leaves. TANJA's finger joints are thickened and strengthened to withstand heavy loads, reduce wear and tear, and extend the service life.

3. Hinge Pin (Pintle)

A cylindrical rod with a joint as its rotation axis. It must be sturdy, wear-resistant, and precisely installed. The TANJA hinge pin undergoes heat treatment and possesses hardness and corrosion resistance in harsh environments.

4. Fixing Holes

The pre-drilled holes on the blade are used for installing screws, bolts or rivets. The dimensions and spacing comply with industrial standard safety accessories. Customized modes can be used to improve installation efficiency.
