FAG Current-Insulated Single Row Cylindrical Roller Bearing NJ222-E-XL-M1-F1-J20AA-C4

FAG Current-Insulated Single Row Cylindrical Roller Bearing NJ222-E-XL-M1-F1-J20AA-C4

The FAG NJ222-E-XL-M1-F1-J20AA-C4 is a current-insulated cylindrical roller bearing with a 110mm bore and 200mm outer diameter, designed to handle high loads. Its ceramic-coated outer ring provides electrical insulation, preventing damage from stray currents.

This bearing supports dynamic loads up to 345 kN and static loads up to 345 kN, making it suitable for heavy-duty applications. It operates smoothly at speeds up to 3250 RPM, even in demanding conditions.

The brass cage ensures durability and reduces friction, while the C4 radial clearance allows for thermal expansion. It’s compliant with RoHS and REACH standards, ensuring safe and eco-friendly use.

Ideal for electric motors, generators, or industrial machinery where electrical insulation is needed. The coating resists voltages up to 1000V, offering reliable protection in damp or dry environments.

Weighing 5.4 kg, it’s robust yet manageable for its size. The 200 um insulating layer and high electrical resistance (50MΩ dry, 10MΩ damp) make it a practical choice for preventing electrical wear.
