Sliding mechanisms are systems that allow one object to move smoothly over another. They are commonly used in various applications, such as drawers, sliding doors, and automated machinery. These mechanisms often utilize components like rails and rollers to reduce friction, enabling easy movement. There are different types of sliding mechanisms, including linear guides and ball bearings. Linear guides provide a straight path for movement, while ball bearings help distribute weight and minimize resistance. Both types enhance efficiency and durability in mechanical systems, making them essential in engineering and design.
