FAG Current-Insulated Single Row Cylindrical Roller Bearing NU2214-E-M1-J20AA-C3

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU2214-E-M1-J20AA-C3

The FAG NU2214-E-M1-J20AA-C3 is a current-insulated cylindrical roller bearing with a 70mm bore and 125mm outer diameter, designed to handle heavy radial loads up to 185 kN. Its ceramic-coated outer ring provides insulation against electrical currents, with a breakdown voltage of up to 1000V.

The brass cage ensures smooth operation at speeds up to 3850 rpm, while the C3 radial clearance allows for thermal expansion in demanding conditions. The coating offers high electrical resistance, even in damp environments (10MΩ).

This bearing is ideal for electric motors or generators where electrical insulation is crucial. Its robust design and compliance with RoHS and REACH standards make it a reliable choice for industrial applications. Weighing 1.661kg, it balances durability with manageable size.
