FAG Current-Insulated Single Row Cylindrical Roller Bearing NU215-E-XL-M1-F1-J20B-C4

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU215-E-XL-M1-F1-J20B-C4

The FAG NU215-E-XL-M1-F1-J20B-C4 is a current-insulated cylindrical roller bearing with a 75mm bore and 130mm outer diameter, designed to handle electrical currents. Its outer ring features a ceramic coating (J20B) to prevent current damage, while the brass cage ensures durability.

This bearing supports dynamic loads up to 155 kN and static loads of 157 kN, with a reference speed of 4400 RPM. The C4 radial clearance allows for thermal expansion, making it suitable for high-speed applications.

The insulating coating provides a breakdown voltage of up to 500V, with electrical resistance of 50MΩ when dry. It’s ideal for electric motors or generators where stray currents are a concern.

Weighing 1.4kg, it’s robust yet manageable for installation. Compliant with RoHS and REACH standards, it’s a reliable choice for industrial and electrical machinery.
