idlerrullar
Idlerrullar, often transliterated from Swedish as "idle rollers" or "idler rollers," are mechanical components used in various systems to guide, support, or tension a moving element, most commonly a belt or a chain. They are essentially unpowered wheels or spools that rotate freely and serve to redirect or stabilize the path of the moving component. Unlike drive rollers or sprockets, idlerrullar do not impart motive force.
The primary functions of idlerrullar include preventing belt sag, maintaining proper belt tension, guiding the belt
Idlerrullar are typically constructed from durable materials like steel, aluminum, or various types of plastic or
