FAG Current-Insulated Bearings 6317-M-J20AB-C3

FAG Current-Insulated Bearings 6317-M-J20AB-C3

The FAG 6317-M-J20AB-C3 is a current-insulated bearing with dimensions of 85mm bore, 180mm outer diameter, and 41mm width. 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 6600 RPM. The brass cage ensures durability and reliable performance under stress.

The ceramic coating provides high electrical resistance (50MΩ when dry) and can withstand voltages up to 500V. This makes it ideal for electric motors or generators where electrical currents might cause issues.

Weighing 4.9kg, this RoHS-compliant bearing suits industrial applications requiring both mechanical strength and electrical insulation. Its C3 clearance allows for thermal expansion in demanding environments.
