Introduction to Stainless Steel Friction Hinge

Stainless steel friction hinge, or torque hinge, is a specialty hinge that gives resistance to the pivoting motion. These hinges are typically used to control motion or hold a pivoting object opened or closed. They are plated and polished for higher surface strength and corrosion resistance, making it suitable for a wider range of applications.

Types of Stainless Steel Friction Hinge

One-Way Friction Hinge
With all friction hinges, torque is the key to holding an open device's position. In the case of a one-way friction hinge, constant torque is only manifested in one direction without any torque in the reverse direction.
One-way friction hinges make it easy to open a lid, device, panel, door, or display, but they make it more difficult to close them. This particular function is helpful for use with large or heavy doors.

Detent Friction Hinge
The benefit of detent friction hinges is their ability to hold an opening completely closed to prevent springback and hold connected objects in place. Once a door or opening is opened, it remains open and in place. Unlike traditional hinges that allow for free motion, detent friction hinges limit the motion of an opening and hold the door or opening in position, removing its ability to move or reposition.

Adjustable Friction Hinge
Adjustable friction hinges make it possible to adjust the amount of torque by rotating a screw with a 180° rotation at the top of the hinge shaft. They are referred to as position control hinges since they allow the flexibility to define and change the movement, operation, and positioning of a panel or door. These changes are applied without additional cost, hardware, or installations. In addition, adjustable friction hinges can have concealed mountings for a clean presentation.

Friction Stay Hinge
Friction stay hinges are variable torque hinges used for security and for providing safe opening and closing of windows. They are adjustable hinges placed in a slide to provide controlled movement of windows.

Top Hung Friction Hinge
Top hung friction hinges have a handle at the bottom of the window, with the friction hinge placed at the top of the window. The window opens from the bottom. The friction hinge springs back to facilitate its opening. Windows with top hung friction hinges are pushed outwards from the bottom.
The sizes of top hung hinges can be adjusted according to the size of a window, with sizes ranging from 8 to 24 inches (20 to 61 cm). They are made of stainless steel with a thickness of 0.1-0.2 inches (2.6 to 3 mm). Top hung hinges are used for windows and can be installed with double glazed or aluminum windows.

Side Hung Friction Hinge
Side hung friction hinges are designed so that a window can open like a door. The handle of the window is at the side of the opening, with the hinges at the bottom or top. The window opens from the side like a door or the top like a hatch.

Constant Torque Hinge
One of the names for torque or friction hinges is a constant torque hinge, where the leaf and pin keep the hinge in a set position. There are an endless number of these complex, specially-designed hinges, each of which has a special function to meet the needs of specific applications.
Of the many assorted choices of friction hinges, the constant hinge is the most basic type. It can be opened to any position, which it holds until the appropriate force is applied. This is unlike other models with a preset angle to which they are opened and remain.

Q: How does a friction hinge work?

A: Friction hinges achieve their function by engineering the specific tolerances between the mechanical components. Additional material such as springs and lubricant are often employed to achieve the desired degree of resistance or damping to the hinge movement.
In some cases, the goal is for the object on the hinge to close completely at a desired degree of speed. In others, the torque is used to hold one or both objects to which the hinges are secured to in a specific position, not necessarily on a fully opened or closed position. When used to hold one of the pivoting members in place, they are designed to be moved by a force of a specific amount of torque greater than its rated torque.
Friction hinges are often customized or custom designed to meet the exact torque requirements of critical applications. Custom designs can provide one-way hinges, in which all the resistance is only in one direction; two-way hinges that have equal damping in both directions, or a combination of both. Design variables include lubricant viscosity, construction material, and degree of space tolerance between components to meet specific applications, such as medical, rugged, high or low temperature, or hazardous environments.

Q: What factors should be considered when choosing a stainless steel friction hinge?

A: Load and Torque Requirements
It's essential to ensure that the selected hinge can withstand the required load without experiencing sagging or failure. This is especially important if you need a heavy-duty friction hinge. You'll need to determine the load capacity and torque specifications necessary for your application, considering the maximum weight or force the hinge must support and the required torque for controlling movement.
Range of Motion
Take into account the desired range of motion for your application. Stainless steel friction hinges are available in various designs, allowing for different angles of rotation. Choose a hinge that suits your specific requirements.
Coefficient of Friction, Normal Force and friction Force
You'll need to choose your hinge based on the calculation of these factors to ensure optimum performance. This friction force represents the resistance to motion generated by the friction hinge.
Environmental Conditions
Consider the environmental conditions in which the hinge will operate. Factors like temperature, humidity, exposure to dust or chemicals, and outdoor usage can impact the choice of materials and coatings for the hinge.
Size and Form Factor
Choose a stainless steel friction hinge that fits within the available space in your application without obstructing other components or interfering with the device's functionality.
Mounting Method
Determine how the hinge will be affixed in your application. They can be surface-mounted, concealed, or integrated into the design. Consider ease of installation and aesthetic considerations.
Adjustability
Some friction hinges offer adjustability or the ability to fine-tune the friction force. Depending on your application, adjustable friction hinges may be necessary for achieving precise positioning.

Q: What are the differences between friction hinge and butt hinge?

A: Design: A friction hinge is usually a single, sturdy unit with an integrated mechanism that allows controlled friction and smooth movement. On the other hand, a butt hinge consists of two separate plates attached to the window sash and frame, joined together by a pin.
Aesthetics: Friction hinges are commonly used for brand new windows, traditional or otherwise, as they offer a clean and streamline appearance where the hinges are concealed. Butt hinges, on the other hand, are visible from the outside.
Functionality: A friction hinge is designed to hold the window at any desired position without the need for additional hardware such as a casement stay. It provides frictional resistance to the opening and closing force to keep the window in place, which makes it useful for ventilation control and easy cleaning. Butt hinges, on the other hand, only provide rotational movement for the window and do not hold it at specific positions. A casement stay must be used in conjunction with a butt hinge.
Adjustability: Friction hinges are typically adjustable, allowing for fine-tuning of the friction levels and opening angles. This adjustability feature is useful for maintaining consistent tension across multiple windows. Butt hinges, however, do not offer adjustability once installed.
Load-bearing capacity: Butt hinges are generally stronger and can bear heavy loads compared to friction hinges, which are primarily designed for lightweight residential windows.

Q: How to replace the friction stay hinges on your windows?

A: You may find it easier to remove the glass first (this makes the sash easier to handle and also lighter in weight).
Remove the sash from the frame and then the old hinges from the sash.
Open the new friction hinge to about half way or so you can see all of the screw holes and making sure that you open the hinge to the correct handing.
Place the hinge on the sash with the top locating point overhanging the sash by about 5mm and making sure that the plastic head of the hinge doesn't snag on the top of the sash. Fit your screws into the elongated holes first and check operation and adjust before you fit the last screw into the middle hole.
Offer the sash to the window frame and fit the top screw in first both sides.
You can now check to see if any adjustment is required and adjust accordingly.
Fit the last screws in and check operation for correct opening.
What are adjustable friction hinges and how do they work?
Adjustable friction hinges are mechanical bearings that offer an adjustable friction levels. All hinges generate friction during use. After all, they are mechanical bearings with moving parts. When you pull open a door, for instance, the hinges' leafs will move. This movement will generate friction that affects the ease of which the door is opened.
There are different types of adjustable friction hinges. Some of them feature a friction brake. You can turn the friction brake to adjust the friction level.
Other adjustable friction hinges feature a dedicated screw or fastener that controls the friction level. You'll still need to install them by driving other fasteners through the hinges and into the underlying objects. But these adjustable friction hinges feature a separate built-in screw or fastener. Turning this screw or fastener will adjust the friction level.

Q: What are the types of friction from a friction hinge?

A: Curl Friction
Curl friction generates friction from the presence of a spring steel sheet wrapped around a shaft. Spring steel can return to its initial position without deformation. As with disc and pipe friction, the curl friction structure is located inside the hinge.
Disc Friction
Disc friction is the friction that happens between alternating, disc-shaped rotating bodies and fixed stationary bodies. The stationary body resists the motion of the rotating body.
Pipe Friction
Pipe friction is a method of joining tight-fitting parts that depend on friction. It creates a lasting bond with perfect alignment. In a friction hinge, it is the shaft forced through the knuckles.
