FAG Current-Insulated Single Row Cylindrical Roller Bearing NU219-E-M1-F1-J20B-C4

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU219-E-M1-F1-J20B-C4

The FAG NU219-E-M1-F1-J20B-C4 is a current-insulated cylindrical roller bearing with a 95mm bore and 170mm outer diameter, designed to handle electrical currents. Its outer ring features a ceramic coating (J20B) to prevent current damage, making it ideal for electric motors.

With a dynamic load rating of 260 kN and a static load rating of 265 kN, it supports heavy radial loads while spinning smoothly at up to 3700 RPM. The brass cage ensures durability and reduces friction.

The C4 radial clearance allows for thermal expansion, and the coating resists voltages up to 500V. It weighs 3.11kg and complies with RoHS and REACH standards.

Perfect for applications like wind turbines or industrial drives where electrical insulation is needed. The coating maintains high resistance even in damp conditions (10MΩ).
