Certain design factors are taken into consideration when the bearing material
selection is made design/construction, mating material hardness,
temperature, corrosion resistance required and surface condition.
Generally speaking, the surface hardness of the mating material should be at
least 100 HB higher then that of the LUMET bearing. For bearing materials with
a higher hardness (such as, aluminum bronze alloy) the surface of the
mating material should be hardened. In cases of high corrosion resistant mating
material, the use of a high alloy bearing material is recommended. High corrosion
resistance and high hardness can be achieved by the application of hard chrome
plating or nickel plating. The plating layer should have a thickness of at least
50 mm and a hardness of 64 HRC. The surface of the supplementing material should
be ground to a surface roughness of 0.8 to 1.0 RMS.
It is recommended that complete application information be provided.
