FAG Current-Insulated Single Row Cylindrical Roller Bearing NU216-E-XL-M1-F1-J20AA-R105-125NA

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU216-E-XL-M1-F1-J20AA-R105-125NA

The FAG NU216-E-XL-M1-F1-J20AA-R105-125NA is a current-insulated cylindrical roller bearing with an 80mm bore and 140mm 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 166 kN and a static load rating of 168 kN, it supports heavy radial loads while maintaining smooth operation. The brass cage ensures durability, and it can reach speeds up to 4200 RPM.

The insulating coating provides high breakdown voltage (up to 1000V) and excellent electrical resistance (50MΩ dry, 10MΩ damp). Its normal radial clearance (Cn) allows for reliable performance in varying conditions.

Weighing 1.71kg, this bearing is robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a safe choice for applications where electrical insulation is critical.
