DEGOL Exterior door hinge types 

1.Ball Bearing Hinge

While door hinges do wear down over time, some naturally last longer than others. One of the most durable door hinge styles is the ball bearing hinge. They’re built for heavier and wider doors.

The ball bearing is placed between two knuckles to reduce friction which wears down your hinges. Entry doors see the most traffic so it only makes sense that the hinges face the most friction.

Another benefit of ball bearing hinges is that they’re permanently lubricated. This allows the door to open and close easier and smoother – also helping reduce the amount of friction.

3.Butt Hinge

One of the most common door hinges is the butt hinge. Butt hinges are composed of two identical leaves – one that's attached to the moving component and the other on the fixed component. They’re attached by a curled barrel, also known as the knuckle, which allows the door to open.

One of the major reasons they're common for entry doors is because they're designed to support a lot of weight. Many steel, wood and fiberglass doors can be heavy which can damage weaker hinges. However, butt hinges won't buckle under the weight.
