The FAG NU310-E-XL-M1-J20B-C4 is a current-insulated cylindrical roller bearing with a 50mm bore and 110mm outer diameter, designed to prevent electrical damage. Its outer ring features a ceramic coating (J20B) that resists up to 500V, making it ideal for electric motors or generators.
With a dynamic load rating of 131kN and a static load rating of 114kN, it handles heavy radial loads smoothly. The brass cage ensures durability, while the C4 radial clearance allows for thermal expansion in high-speed applications (up to 6000r/min).
The insulating coating maintains high electrical resistance (50MΩ dry, 10MΩ damp), protecting against stray currents. Its compact 27mm width and 1.29kg weight make it easy to integrate into existing systems.
Compliant with RoHS and REACH standards, this bearing is a reliable choice for industries like wind energy or rail transport where electrical insulation is critical.
