Hydrodynamic Journal Bearing

Hydrodynamic Journal Bearing .

Journal bearings execute a sliding motion between a bearing journal and a bearing shell. This sliding motion is usually lubricated by an intermediate medium. 
 Hydrodynamic journal bearings give wear-free continuous duty for large diameters at high rotational speeds, and are suitable for high and shock-type loading. They are usually constructed as split bearings. Frictional heat occurring during operation must be dissipated by the lubricant. 
The is a horizontally split hydrodynamic pedestal journal bearing. The bearing shells are supported from a face in the spherical bearing housing so as to ensure uniform transfer of any forces that arise to the bottom housing. The journal bearing is lubricated by a loose lubricating ring. Standard commercially available mineral oils can be used. 
An auxiliary shaft is supplied together with the bearing as an aid to assembly and functional testing.
