The SKF 6311MC3SQ77 is a high-performance INSOCOAT deep groove ball bearing designed for applications requiring electrical insulation. Featuring an aluminium oxide coating on the outer ring, it provides a minimum breakdown voltage of 1000 V DC and an insulation resistance of at least 50 MΩ. This bearing has a 55 mm bore diameter, 120 mm outer diameter, and 29 mm width. It incorporates a machined brass cage (M) and C3 radial internal clearance, which is greater than normal, allowing for thermal expansion and misalignment. With a basic dynamic load rating of 95 kN and a static load rating of 56 kN, it is suitable for demanding industrial environments.
