Sliding doors slide horizontally using a track and roller system, often referred to as the "running gear." This system allows for smooth and efficient opening and closing.
Here's a breakdown of the sliding door mechanism:
-
Track: The track is a grooved pathway, typically made of metal (aluminum, steel) or durable plastic, that is installed along the top or bottom (sometimes both) of the door frame. The door follows this track.
-
Rollers/Wheels: Rollers (or wheels) are attached to the door itself. These rollers fit within the track, allowing the door to move smoothly along its length. High-quality rollers are often made with ball bearings for reduced friction.
-
Mechanism: This refers to the combined track and roller/wheel system that supports the door and enables sliding movement. The 'running gear' sits at the bottom of the door to help them slide open horizontally.
Here's a more detailed explanation:
-
Weight Distribution: The weight of the door is primarily supported by the rollers.
-
Friction Reduction: The rollers minimize friction between the door and the track, allowing for easy sliding.
-
Horizontal Movement: The track guides the rollers, ensuring the door moves only in a horizontal direction.
-
Types of Sliding Doors & Systems: There are different types of sliding doors, including:
- Bypass Sliding Doors: These doors slide past each other on parallel tracks. Often seen in closets.
- Pocket Doors: These doors slide into a recess within the wall, effectively disappearing when open.
- Patio Doors: Large glass sliding doors commonly used to access patios or decks.
Maintenance: To ensure smooth operation, sliding doors require regular maintenance, including cleaning the tracks and lubricating the rollers.
