FAG Current-Insulated Single Row Cylindrical Roller Bearing NU328-E-M1-J20AA-C3

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU328-E-M1-J20AA-C3

The FAG NU328-E-M1-J20AA-C3 is a current-insulated cylindrical roller bearing with a 140mm bore and 300mm outer diameter, designed for heavy-duty applications. Its outer ring features a ceramic coating to prevent electrical arcing, making it ideal for environments with stray currents.

With a dynamic load rating of 680 kN and a static load rating of 930 kN, it handles high loads efficiently. The brass cage ensures smooth operation at speeds up to 1720 rpm, even in demanding conditions.

The C3 radial clearance allows for thermal expansion, while the insulating coating offers high electrical resistance (50MΩ dry, 10MΩ damp). This makes it suitable for use in electric motors, generators, or wind turbines where electrical insulation is crucial.

Weighing 22.6 kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for modern machinery.
