Plain bearings are designed to provide reliable support for rotating shafts while minimizing friction and wear. When oil is present between a static shaft and the plain journal bearing, it helps form a thin film that prevents metal-to-metal contact. At the start of rotation, the journal tends to roll up the bearing surface, creating friction. However, once friction slip occurs, oil fills the clearance space, clinging to the surface and creating a protective layer.
As shaft rotation speeds up, oil is continuously carried to the underside of the shaft, increasing pressure and forming a strong lubricating film. This film, which builds with speed, keeps the shaft separated from the bearing, preventing direct metal wear and ensuring smooth operation.
Plain bearings are vital for maintaining the longevity and efficiency of mechanical systems by offering effective protection against friction and wear. This complete pack delivers everything needed for reliable, long-lasting performance in demanding applications.
