Introduction to the Basic Structure and Working Principle of Bearing Hinges

Introduction

Bearing hinges are an essential component of doors and windows. They provide support and allow smooth movement of the door or window. Understanding the basic structure and working principle of bearing hinges is important for maintaining and repairing them. In this article, we will discuss the basic structure and working principle of bearing hinges.

Basic Structure of Bearing Hinges

There are three basic components of bearing hinges:

1. Leaf: The flat metal part that attaches to the door or window.
2. Pintle: The cylindrical metal part that attaches to the frame.
3. Bearing: The small metal balls or rollers that sit between the leaf and pintle to allow smooth movement.

Working Principle of Bearing Hinges

The working principle of bearing hinges is based on the concept of rotation. When the door or window is opened or closed, the leaf rotates around the pintle. The bearing balls or rollers reduce friction and allow smooth rotation. The number of bearings used in a hinge depends on the weight and size of the door or window.
