FAG Current-Insulated Single Row Cylindrical Roller Bearing NU222-E-M1-F1-J20AA-C3

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU222-E-M1-F1-J20AA-C3

The FAG NU222-E-M1-F1-J20AA-C3 is a current-insulated cylindrical roller bearing with a 110mm bore and 200mm 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 345 kN and a static load rating of 365 kN, it handles high radial loads efficiently. The brass cage ensures smooth operation at speeds up to 3250 rpm.

The insulating coating provides a breakdown voltage of up to 1000V and maintains high electrical resistance, even in damp conditions. This makes it suitable for use in electric motors or generators where electrical insulation is crucial.

Weighing 5.5 kg, it’s robust yet manageable for its size. Compliant with RoHS and REACH standards, it’s a reliable choice for industrial machinery requiring both mechanical strength and electrical protection.
