FAG Current-Insulated Single Row Cylindrical Roller Bearing NU218-E-M1-C3-F1-J20AA

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU218-E-M1-C3-F1-J20AA

The NU218-E-M1-C3-F1-J20AA is a current-insulated cylindrical roller bearing with a 90mm bore and 160mm outer diameter, designed to prevent electrical damage. Its outer ring features a ceramic coating, providing insulation up to 1000V DC.

This bearing handles dynamic loads up to 215 kN and spins smoothly at speeds up to 3900 RPM. The brass cage ensures durability, while the C3 radial clearance allows for thermal expansion in demanding conditions.

The ceramic coating offers high electrical resistance (50MΩ dry, 10MΩ damp), protecting against stray currents. It’s ideal for electric motors or generators where electrical insulation is crucial.

Weighing 2.58kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for heavy-duty applications.
