FAG Current-Insulated Single Row Cylindrical Roller Bearing NU234-E-XL-M1-J20AA-C3
FAG Current-Insulated Single Row Cylindrical Roller Bearing NU234-E-XL-M1-J20AA-C3

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU234-E-XL-M1-J20AA-C3

The FAG NU234-E-XL-M1-J20AA-C3 is a current-insulated cylindrical roller bearing with a 170mm bore and 310mm outer diameter, designed for heavy-duty applications. Its outer ring features a ceramic coating to prevent electrical damage, making it ideal for environments with stray currents.

With a dynamic load rating of 700 kN and a static load rating of 780 kN, it handles high loads efficiently. The brass cage ensures durability, while the C3 radial clearance allows for thermal expansion in demanding conditions.

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 critical.

Weighing 18.3 kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for modern machinery.
