Electrically Insulated Ball Bearings 6309/C3VL0241

Electrically Insulated Ball Bearings 6309/C3VL0241

The 6309/C3VL0241 is an electrically insulated ball bearing with a 45mm bore and 100mm outer diameter, designed to prevent electrical currents from passing through. It handles dynamic loads up to 56kN and spins smoothly at speeds up to 9500 RPM.

Its outer ring features a special coating with a breakdown voltage of 1000-3000V, making it ideal for electric motors or generators. The C3 radial clearance ensures reliable performance under varying temperatures.

Weighing just 0.8kg, it’s lightweight yet robust for industrial use. Compliant with RoHS and REACH standards, this bearing is a safe choice for applications where electrical insulation is crucial.

The sheet metal cage adds durability, while the 100-500µm coating thickness provides consistent insulation. Perfect for wind turbines or railway systems where electrical arcing is a concern.
