Exposure of the surface of the sliding bushing

Bearing surface exposure analyzed as follows:
Journal actual contact with the sliding bearing surface, the actual number of contact points available per unit area to represent.
The more points of contact, more detailed, more uniform, indicating that the sliding bearing scraping the better, on the contrary, it means bearing scraping bad. Generally the more detailed the more points of contact, the greater the difficulty scraping.
Production of contact points should be determined according to the performance and working conditions of sliding bearings.
① Press can withstand the load direction can be divided into radial (radial) bearing and thrust (axial) bearing types.
② can be divided according to type of lubricant oil lubricated bearings, grease lubricated bearings, water lubricated bearing, a gas bearing, solid lubricating bearings, bearing magnetic fluid and magnetic bearings 7 class.
③ Press lubricating film thickness can be divided into thick and thin film lubrication bearings lubricated bearing types.
④ Press bearing materials can be divided into bronze bearings, cast iron bearing, plastic bearings, jewel bearings, powder metallurgy bearings, self-lubricating bearings and oil bearings.
⑤ Press bush bearing structure can be divided into round, oval bearing, three oil leaves bearing, ladder bearing surfaces, tilting pad bearings and foil bearings.
