Hinge Bearing Types
Many door hinges for standard applications are plain bearing hinges, meaning that the hinge knuckles bear on each other. Plain bearing hinges are less expensive and work great for lighter or limited use doors. Hinges do wear out over time especially on high-use doors and heavy or wide doors such as an entry door. An upgrade to the plain bearing hinge is the Ball Bearing Hinge which has small ball bearings between the hinge knuckles to reduce friction. Ball bearing hinges increase the life of the hinge, tend to be quieter, and make the door easier to open.
