Upper & Lower Folding Ball Bearings

The upper and lower accordion door bearings are essential components in folding door systems, designed to guide the door panels along the track and support the door weight. By reducing friction and ensuring smooth movement, these bearings provide quiet and effortless opening and closing while minimizing stress on hinges and other hardware components. The use of high‑quality bearings significantly improves durability, operational performance, and the service life of accordion door systems.
