Sliding door bearings, also known as patio door bearings or sliding glass door bearings, are the small metal or plastic components that help a sliding door move smoothly along its track. They are typically located in the upper and lower corners of the door and are responsible for reducing friction and providing support for the door as it moves back and forth. Over time, these bearings can become worn or damaged and may need to be replaced to ensure proper function of the sliding door.

Sliding door bearings are used to reduce friction and provide support for a sliding door as it moves along its track. They are typically located in the upper and lower corners of the door and are responsible for allowing the door to slide smoothly and easily. The bearings help to distribute the weight of the door evenly and prevent it from binding or getting stuck on the track. They also reduce wear and tear on the door and track, increasing the longevity of the door and making it easier to open and close.

The bearings are also used to keep the sliding door in the correct position, ensuring that it is properly aligned and does not sag or twist. This helps to improve the overall performance and appearance of the door and makes it less likely to get damaged or need repairs. Additionally, by reducing friction, they also help save energy consumption, making the door more efficient.
