A type of mechanical bearing formed between two parts allowing one to be rotated relative to the other e.g. door hinges.
In concrete structures, a point where the element is purposely reduced in size to such an extent that it is free or nearly free to rotate at that point. Sometimes an actual steel hinge is embedded in the concrete or the hinge is made by creating a plane of weakness in the concrete.
Ball Bearing Hinge
A hinge equipped with ball bearings between the hinge knuckles to reduce friction.
One leaf attaches to the door’s edge, the other to its jamb.
Clip on Hinge
