Plain bearing hinges are suitable for light use only. They have no extra parts in the knuckle like a ball bearing or washer to help reduce friction and they are a basic butt hinge with metal to metal contact. The knuckle sections interlock to wrap around the pin to connect the hinge flaps/leaves together. Plain bearing hinges are very standard butt hinges. These types of hinges are best installed on lightweight storage room doors, closet doors, or temporary doors. They should only be installed on residential or very light-duty commercial internal doors and never on an entry door.
