In terms of its role, Journal Bearing is to support and support the shaft. Unlike roller and ball bearings, journal plain bearings do not have any rolling elements. As a result, they are only capable of supporting radial loads, which stem from the weight of the shaft.
Self-lubricating Journal Plain Bearings
Plain Bearings are an important part of mechanical fittings. Responsible for the transfer or counter-transfer of solid lubricant from the hole or groove to the friction surface at high speeds, a well-lubricated, firmly adhered and uniformly covered solid transfer film is formed on the friction surface, substantially reducing frictional wear.
