Types of Friction Hinges

Friction hinges are available in a variety of sizes and materials to meet the requirements of specific applications. When selecting a friction pivot for their product, engineers should take into consideration factors like environmental conditions, load and aesthetic preferences.

door hinge repair enfield Repair My Windows And Doors should consider the normal force when choosing a hinge based on friction. This is the force perpendicular to contact surfaces. This is crucial because it determines how much pulling force is required to open the item on which the hinges are installed.

Restricted friction hinges

Friction hinges use friction to create resistance to the pivoting motion of doors, lids, and other objects. They are different from traditional hinges, which depend on lubricants as well as mechanical bearings to enable them to pivot. Friction hinges are available in a variety of sizes and configurations and are a great solution for applications requiring the ability to limit the movement or alter the position of an object.

Cold-rolled steel is the most commonly used metal used in friction hinges. Its low melting temperature and robust physical properties make it a popular choice for many friction hinges. Aluminum is also a sought-after material due to its durability and resistance to corrosion. Aluminum is comparatively lightweight and easy to install. Its strong tensile strength allows it to support large doors and windows with no deformation under stress.

Some friction hinges are designed with a spring inbuilt which limits the force needed to open and close the door or device. These are called detent-friction hinges, and they are perfect for applications that require an exact opening angle. Detent friction hinges are utilized in kitchen cabinets, laptops storage cabinets, as well as machine covers.

Other kinds of friction hinges are designed to create a smooth closing motion that is slow. They are referred to as soft-close hinges and they make use of hydraulics to reduce the amount of force required to close a door or lid. They protect against damage from a sudden jarring closing.

There are a variety of torque ratings for friction hinges. Some hinges are designed to withstand more force than others, while others are designed to handle more torque. The force needed to open a hinge depends on the number of hinges, their position and the size of the objects that are attached to them.

Window friction hinges that are restricted (also known as restrictor friction stays) are designed to meet the building regulations for fire escape safety and are compatible with all aluminum, uPVC and timber windows. They can be fitted to lock a window's opening to a safe and secure position and can also be fitted with an easy-to-clean slider to open the exterior of your window.

Steel friction hinges

Steel friction hinges are used in heavy-duty applications like furniture and doors for industrial use. They can be able to withstand high torque and are available in various lengths. They are simple to install and maintain. They can also be modified to meet specific application requirements with a variety of options for adjusting hinge position. These include knuckles, barrels, and pins.

The stainless steel friction hinges are well-known for their strength and resistance to corrosion. They are utilized in a variety of different applications, including cabinet doors, laptop computers storage cabinets, and machine covers. They can be mounted on the surface or concealed. They are typically made of steel, however certain models also feature aluminum or plastic. The choice of material is based on the setting where the hinge will be used. Factors such as the nature of the climate, temperature, and humidity can impact the specification of the material.

If the hinge is exposed to salt environments then stainless steel would be the best option as it is resistant to corrosion and rust. Brass and bronze are also resistant to salt corrosion, and can be used in decorative applications. They aren't as durable as stainless steel.

Some friction hinges have a constant torque control that allows them to be moved in any direction. They are generally more expensive, but they are perfect for hygienic as well as corrosive applications. They are available in aluminum, zinc, or, for a more durable alternative, stainless steel.

It is crucial to consider the weight and the size of the door or enclosure when deciding which hinge is best for you. It is also important to determine the amount of torque needed. Hinges are usually designed to handle up to 100 kg but you can find custom sizes to satisfy your specific needs.

It is crucial to take into account the aesthetics when choosing a hinge. Hinges can be seen and others are hidden to create a seamless look. Hinges can be painted to match the color of your furniture or brushed to a dull finish for a more subtle look.

Restrictor friction hinges

The hinges that are restricted by friction restrict the amount to which windows can be opened, and are ideal for rooms that have an issue with child safety. By pressing a button the restriction can be removed. The window will open fully like it normally. Please refer to the diagram in our gallery of images to determine what kind of hinge you require.

These uPVC hinges for windows are available in both 13mm non handed and 17mm handed stack heights that will suit most windows including uPVC, aluminium and timber. These uPVC hinges come in pairs and can be easily fitted to your existing uPVC windows to increase the safety of children and increase security at home.

In contrast to conventional hinges that are fixed, the hinges of a restrictor can be adjusted, allowing the perfect amount of resistance for any closing and opening motion. In addition their spring-loaded mechanism aids to reduce noise and protects the hinges themselves from damage caused by a forceful opening. Restriction friction hinges combine security, noise reduction and hinge protection to offer the ultimate in controlled movement. Installation requires specialized knowledge to get the most efficient results.

Adjustable friction hinges

Torque hinges, also called friction hinges or position control hinges, utilize friction to resist movement and keep doors, lids, or panel in place to ensure safety and ease of use. They come in various torque strengths and mounting positions as well as specifications. A lot of them are adjustable, which means that engineers can make them unique for specific uses. Engineers must consider the function that the hinge will deliver along with the weight and dimensions of the parts it is designed to hold when choosing the hinge.

The materials used to construct adjustable friction hinges are cold-rolled steel, stainless, bronze and aluminum. The choice of material is based on the application and environment. Bronze, for instance, is extremely resistant to corrosion and has great ductility, making it a great choice for marine applications. Brass is also a popular choice because of its machinability, as well as its strength. It is lightweight and is more resistant to saltwater corrosion than any other metal.

Calculating the torque that hinges produce and the maximum torque it can handle is a great method to determine which hinge is ideal for your particular project. Then, engineers can select the appropriate hinge to meet the needs of their clients and users. Engineers must also take into consideration the durability and life span of the hinge in order to avoid damaging equipment.





The most popular friction hinges are single-way force, and are available in a variety of models. They can be equipped with balanced or centralized torque as well as left- or right-hand opening. Steel is the most common material however they can be constructed from other materials.

In addition to the force of hinges, engineers must take into consideration the amount of free play. This is the amount of space that a flap or door can move before the hinge flexes back and activates its free-stop mechanism. This is an excellent feature to have in medical devices, LCD displayers and other products that need to be opened and closed repeatedly. This will stop accidental slamming, and reduce the possibility that the device could be damaged or user could be injured.
