More than just a hinge: New functional hinges from norelem

Spring hinges can be found in all kinds of situations in which doors or hatches need to open or close automatically. With these products, the customer has a choice between simple sheet metal hinges made from steel or stainless steel and featuring a visible spring, or spring hinges made from aluminium with an in-built tensioning spring. The steel or stainless steel spring hinges are available in sizes between 50 mm and 240 mm, and with a maximum torque of 2.55 Nm. The aluminium models, meanwhile, can be obtained in sizes from 30 mm to 100 mm and with a maximum torque of 3.8 Nm. All the spring hinges are also available with the option of a closing or opening spring. The maximum opening angle is between 180° and 270°, depending on the version.

Hinges featuring adjustable friction are also known as torque hinges and make it possible to position a door at any angle within the opening angle range. Using a setscrew, the frictional resistance of the hinge can be freely adjusted between 0 and 1 Nm in the small version and between 0 and 5 Nm in the large version. The setscrew braces two narrow friction cones inside the torque hinge against one another. The frictional resistance counteracts the movement of hatches and doors, and is able to hold them in the required position.
