FAG Current-Insulated Single Row Cylindrical Roller Bearing NU1038-M1-J20AA

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU1038-M1-J20AA

The FAG NU1038-M1-J20AA is a current-insulated cylindrical roller bearing, measuring 190mm in bore diameter and 290mm outside diameter, with a width of 46mm. Its outer ring features a ceramic coating for electrical insulation, preventing current damage.

With a dynamic load rating of 435 kN and a static load rating of 550 kN, it handles heavy radial loads efficiently. The brass cage ensures smooth operation at speeds up to 2410 rpm.

The ceramic coating provides high electrical resistance (50MΩ dry, 10MΩ damp) and a breakdown voltage of up to 1000V. This makes it ideal for electric motors or generators where stray currents are a concern.

Weighing 11.2 kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for demanding applications.
