The SKF 6312-C3-SQ77 is a genuine SKF INSOCOAT deep groove ball bearing, designed with a special aluminum oxide coating on the outer ring to provide electrical insulation. This feature protects the bearing from damage caused by the passage of electrical current, making it ideal for applications in electric motors, generators, and other electrical machinery. It features a C3 internal clearance, which is greater than normal, allowing for thermal expansion and misalignment. With a bore diameter of 60 mm, an outer diameter of 130 mm, and a width of 31 mm, this robust bearing ensures reliable performance and extended service life in demanding industrial environments.
