FAG Current-Insulated Single Row Cylindrical Roller Bearing NU226-E-XL-M1-J20AA

FAG Current-Insulated Single Row Cylindrical Roller Bearing NU226-E-XL-M1-J20AA

The FAG NU226-E-XL-M1-J20AA is a current-insulated cylindrical roller bearing, measuring 130mm by 230mm by 40mm, with a ceramic-coated outer ring for electrical insulation. It handles dynamic loads up to 425 kN and static loads up to 445 kN, suitable for high-speed applications up to 2800 RPM.

Its brass cage ensures durability, while the ceramic coating provides insulation with a breakdown voltage of up to 1000V, ideal for preventing electrical damage. The bearing operates reliably in damp conditions, maintaining an electrical resistance of 10MΩ.

With a normal radial internal clearance (Cn), it offers smooth performance in demanding environments. Compliant with RoHS and REACH standards, it’s a safe choice for industrial use.

Weighing 7.95kg, this bearing is robust yet manageable for installations in electric motors or generators where electrical insulation is critical.
