FAG Current-Insulated Bearings 6320-J20AB-C3

FAG Current-Insulated Bearings 6320-J20AB-C3

The FAG 6320-J20AB-C3 is a current-insulated bearing with a 100mm bore and 215mm outer diameter, designed to prevent electrical damage in machinery. Its outer ring features a ceramic coating, providing insulation against voltages up to 500V.

This model handles dynamic loads up to 182kN and static loads of 140kN, with a reference speed of 4250 RPM. The C3 radial clearance ensures smooth operation under varying temperatures.

The sheet metal cage offers durability, while the coating maintains high electrical resistance (50MΩ dry, 10MΩ damp). It’s ideal for electric motors or generators where stray currents are a concern.

Weighing 7.27kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for modern applications.
