The SQ77 bearings have built-in electrical insulation for reliable protection against current discharge and the resulting electrical corrosion. They are available in three versions: the SQ77 series, with an oxide ceramic insulation layer on...
Coatings can impart additional features for specific application conditions. One of the most important is the use of a thin aluminum oxide layer to form a barrier against electric arcing, which leads to premature bearing failure.Spherical an...
