The use of such small clearances is possible since the bush and journal material is rigid, easily machined and maintains a very stable shape in water (no water soaking).
Elastic bearings are made of polymer materials of good tribological properties and relatively low degree of water soaking.
The use of polymer materials of relatively low hardness allows operation of these types of bearings with a non-hardened journal which constitutes a significant cost advantage.
The relatively low rigidity of bush materials allows for tolerating a certain degree of shaft misalignment.
The above values are representative of typical properties of bearing materials employed in elastic polymer bushes and rigid bushes of sintered bronze with graphite.

The calcination temperature of PG involved 135°C, 430°C and 800°C, according to the DSC results of the raw materials.
Higher curing temperature leads to better activity of atoms, thus it accelerates the reaction among materials.
