Sliding bearings, bearings that work under sliding friction. Plain bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by the lubricating oil without direct contact, but also greatly reduce the friction loss and surface wear, the oil film also has a certain vibration absorption capacity. However, starting friction resistance larger. The part of the shaft supported by the bearing is called the journal, and the part matching the journal is called the bearing bush. The layer of anti-friction material cast on its inner surface for the purpose of improving the frictional properties of the pad surface is called the bearing lining. The bearings and bearing linings are collectively referred to as plain bearing materials. Plain bearing applications are generally under low-speed heavy-duty conditions, or maintenance and filling lubricants difficult operating parts.
Commonly used sliding bearing materials
Commonly used plain bearings are made of bearing alloy, wear-resistant cast iron, copper-based and aluminum-based alloys, powd
