FAG Current-Insulated Bearings 6317-J20AA-C4

FAG Current-Insulated Bearings 6317-J20AA-C4

The FAG 6317-J20AA-C4 is a current-insulated bearing with dimensions of 85mm bore, 180mm outer diameter, and 41mm width, weighing 4.1kg. Its outer ring features a ceramic coating for electrical insulation, preventing damage from stray currents.

With a dynamic load rating of 141kN and static load rating of 97kN, it handles heavy loads while maintaining smooth rotation up to 5000 RPM. The C4 radial clearance allows for thermal expansion in high-speed applications.

The ceramic coating provides excellent insulation, with a breakdown voltage up to 3000V and high electrical resistance. This makes it ideal for electric motors or generators where electrical currents could cause damage.

Compliant with RoHS and REACH standards, this durable bearing uses a sheet metal cage for reliable performance. Its design suits industrial machinery requiring both mechanical strength and electrical insulation.
