Dorma SS Ball Bearing Hinges

What Are Ball Bearing Hinges? Ball bearing hinges look very similar to standard butt hinges. The difference lies at the pivot point, where there are hidden bearings placed between the knuckles of the hinge, either between each knuckle (for heaviest applications) or just a couple of the knuckles.The knuckles of standard hinges rub against each other every time the door opens or closes. Over time, this friction can cause the hinges to squeak or stick. Ball-bearing hinges take the stress off the knuckles of the hinge, so the door opens more smoothly and quietly. This is especially true with heavier doors.We have a great variety of quality ball bearing hinges in a multitude of hard wearing finishes here at Handles 4 doors. Generally made from steel or stainless steel, finishes vary from antique brass and imitation bronze, to satin and polished stainless steel.
