Electrically Insulated Ball Bearings 6216M/C3VL0241

Electrically Insulated Ball Bearings 6216M/C3VL0241

The 6216M/C3VL0241 is an electrically insulated ball bearing with an 80mm bore and 140mm outer diameter, designed to prevent electrical currents from passing through. Its outer ring features a special coating that resists voltages up to 3000V.

This bearing handles dynamic loads up to 72.8 kN and spins smoothly at speeds up to 9500 RPM. The brass cage ensures durability, while the C3 radial clearance allows for thermal expansion in demanding conditions.

The insulation layer, 100-500µm thick, provides electrical resistance of 50-200 MΩ, making it ideal for electric motors or generators. It’s also lightweight at just 1.71kg, despite its robust construction.

Compliant with RoHS and REACH standards, this bearing is a reliable choice for applications where electrical insulation is crucial, such as wind turbines or industrial machinery.
