Rollers are an essential part of any door system, and they come in a variety of shapes, sizes, and materials. The type of roller used for a particular door depends on the door’s design, weight, and the type of opening mechanism used. There are several different types of rollers that are commonly used for doors, including flat track, convex, concave, and ball bearing rollers.
Flat track rollers are the most common type of roller used for doors. They are typically made of steel or aluminum and feature a flat, round surface that is designed to slide smoothly along a track. These rollers are typically used for sliding doors, as they provide a low-friction surface that allows the door to open and close easily.
Convex rollers are another type of roller commonly used for doors. These rollers have a curved surface that is designed to provide a smooth, low-friction movement. Convex rollers are typically used for bi-folding doors, as they provide a secure and reliable opening and closing mechanism.
Concave rollers are similar to convex rollers, but they have a concave surface that is designed to provide a tighter fit in the track. These rollers are typically used for heavier doors, such as garage doors, as they provide a more secure opening and closing mechanism.
Ball bearing rollers are the most expensive type of roller used for doors. These rollers have a ball bearing that is designed to provide a smooth, low-friction movement. They are typically used for doors that require a high level of precision, such as commercial doors.
No matter what type of roller is used for a particular door, it is important to ensure that the roller is properly installed and maintained. Over time, the rollers can wear out or become damaged, which can lead to an inefficient opening and closing mechanism. If the rollers are not properly maintained, they can also cause the door to become noisy or difficult to open and close.
In addition to the types of rollers, there are also several different types of tracks that can be used for doors. The type of track used depends on the type of door and the type of opening mechanism used. For example, if the door is a sliding door, then a flat track is typically used. If the door is a bi-folding door, then a convex or concave track is typically used.
When choosing the type of roller and track for a particular door, it is important to consider the door’s design, weight, and the type of opening mechanism used. This will help ensure that the roller and track are properly installed and maintained, and that they provide a reliable and efficient opening and closing mechanism.
