Some butt hinges use a ball bearing between the knuckles in order to reduce friction. They are perfect for heavy-duty doors that experience frequent use. They also come with pins that are fixed, making them ideal for doors that cannot be opened by removing the pin.


Other types of hinges include a plain bearing lubricated with grease, which reduces friction and allows the hinge to be moved without much force. These are suggested for lighter uses, including cabinet doors. These pins can also be purchased with spun-ends, which ensure the pin is securely held in place.
