JSC «NGT» has mastered production of hard alloy radial bearings using hard alloy plates of different configuration. Intervals between hard alloy plates are filled with wear-resistant material featuring much higher heat conductivity compared to the hard alloy. This excludes cracking of the hard alloy as the result of thermal shock at high radial loads or high sliding speeds.

See below different versions of friction surfaces of the radial bearings which differ by configuration of hard alloy plates, density of their location on friction surfaces, width of intervals between the plates which vary depending on operating conditions of the PDM or turbodrill run.
