FAG Current-Insulated Single Row Cylindrical Roller Bearing NU214-E-M1-F1-J20AA-C4

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU214-E-M1-F1-J20AA-C4

The FAG NU214-E-M1-F1-J20AA-C4 is a current-insulated cylindrical roller bearing with a 70mm bore and 125mm outer diameter, designed to handle electrical currents. Its outer ring features a ceramic coating (J20AA) to prevent current damage, making it ideal for electric motors or generators.

With a dynamic load rating of 141 kN and a static load rating of 138 kN, it supports heavy radial loads while maintaining smooth operation. The brass cage ensures durability, and the C4 radial clearance allows for thermal expansion in demanding conditions.

This bearing can reach speeds up to 4650 rpm and withstand breakdown voltages up to 1000V. Its insulating layer (200µm) provides high electrical resistance (50MΩ dry, 10MΩ damp), reducing the risk of electrical arcing.

Weighing 1.29kg, it’s a robust choice for industrial applications where electrical insulation is critical. Compliant with RoHS and REACH standards, it’s a reliable option for machinery in harsh environments.
