6311 M/C3VL0241

6311 M/C3VL0241 INSOCOAT Single Row Deep Groove Ball Bearings are precision-engineered components designed to mitigate electrical erosion in high-voltage applications. Featuring an advanced aluminum oxide (Al₂O₃) insulating coating on the outer ring, these bearings prevent damaging electric currents from passing through rolling elements, significantly extending service life in motors, generators, and变频器-driven equipment. The 6311 model offers a 55mm bore, 120mm OD, and 29mm width with C3 radial internal clearance for thermal stability under dynamic loads. Its hybrid design combines high-grade steel with insulation technology, ensuring reliable performance in temperatures up to 150°C. The INSOCOAT layer provides 1000 VDC dielectric strength, tested per SKF standards, while maintaining standard lubrication intervals. Ideal for industrial HVAC systems, wind turbines, and railway traction motors, this bearing reduces unplanned downtime by up to 70% compared to non-insulated alternatives. OEMs benefit from its ISO 9001-certified manufacturing and compatibility with standard mounting practices.
