FAG Current-Insulated Single Row Cylindrical Roller Bearing NU320-E-XL-M1-F1-J20AA-C4

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU320-E-XL-M1-F1-J20AA-C4

The NU320-E-XL-M1-F1-J20AA-C4 is a current-insulated cylindrical roller bearing with a 100mm bore and 215mm outer diameter, designed to handle heavy loads. Its ceramic-coated outer ring prevents electrical arcing, making it ideal for electric motors.

With a dynamic load rating of 450 kN and a static load rating of 425 kN, it offers reliable performance under demanding conditions. The brass cage ensures smooth operation at speeds up to 3350 RPM.

The C4 radial clearance allows for thermal expansion, while the insulating coating resists voltages up to 1000V. This bearing is compliant with RoHS and REACH standards.

Perfect for applications in electric motors or generators where electrical insulation is crucial. Its robust design and 8.45kg weight make it suitable for industrial use.
