# Load bearing capacity of a friction hinge?

• RCAN
In summary, the door is 4.5 lbs with a width of 7" and length of 19". It is mounted using a friction hinge at the center. To calculate the total load on the hinge, you will need to know the maximum load bearing capacity of the hinge. The hinge has a length of 3.2", a diameter of .230 inches, and a leaf thickness of .06". However, this may not be the most ideal arrangement for strength as it is recommended to have two hinges, one at the top and one at the bottom. However, in the given application, there is limited space to add two hinges. The door will only open for service twice a year and will remain closed at all other times

That is not the best arrangement for a hinge if you are worried about strength . Ideally you should have two hinges - one at the top of the door and one at the bottom .

Agree with your point regarding two hinges. Here in my application space is limited to provide hinges at top and bottom. The door will be in closed condition always and open only for service (max two times a year)

## 1. What is a friction hinge?

A friction hinge is a type of mechanical hinge that uses friction to hold two components together in a fixed or adjustable position. It is commonly used in doors, cabinets, and other applications that require smooth and controlled movement.

## 2. What factors affect the load bearing capacity of a friction hinge?

The load bearing capacity of a friction hinge can be affected by several factors, including the material and design of the hinge, the amount of friction between the components, and the weight and force applied to the hinge.

## 3. How is the load bearing capacity of a friction hinge determined?

The load bearing capacity of a friction hinge is typically determined through testing and analysis. This involves applying various loads and forces to the hinge and measuring its ability to withstand them. The results of these tests can then be used to determine the maximum load that the hinge can bear.

## 4. Are there different types of friction hinges with varying load bearing capacities?

Yes, there are different types of friction hinges available, each with different load bearing capacities. Some factors that can affect the load bearing capacity of a friction hinge include the materials used, the size and design of the hinge, and the amount of friction between the components.

## 5. What are the applications for a high load bearing capacity friction hinge?

A high load bearing capacity friction hinge is commonly used in heavy-duty applications where there is a need for strong and reliable hinge support. This can include heavy doors, cabinets, and industrial equipment. These hinges are also often used in aerospace and automotive industries, where precision and durability are critical.
