1. A method of manufacturing a bearing assembly comprising at least one substrate assembly, the method comprising:
providing a substrate having one or more recesses;
applying a composition comprising an epoxy into each of the recesses;
inserting at least one bearing element comprising a ceramic-bonded diamond composite into each of the recesses to obtain a wet substrate assembly;
placing a bottom alignment plate into a pneumatic press;
stacking the wet substrate assembly onto the bottom alignment plate;
optionally placing a separator material on top of the wet substrate assembly;
placing a top alignment plate on top of the wet substrate assembly with or without the separator material therebetween;
pressing the wet substrate assembly with the pneumatic press at a pressure of from 0.2 to 0.8 psi Megapascal (MPa) for a period of from 5 to 15 seconds;
removing the pressed wet substrate assembly; and
curing the wet substrate assembly for 24 hours to obtain the at least one substrate assembly.
