NKE Electrically Insulated Single Row Cylindrical Roller Bearing NU324-E-M6-C3-SQ77

NKE Electrically Insulated Single Row Cylindrical Roller Bearing NU324-E-M6-C3-SQ77

The NU324-E-M6-C3-SQ77 is an electrically insulated cylindrical roller bearing with a 120mm bore and 260mm outer diameter, designed for heavy-duty applications. Its outer ring features a special coating to prevent electrical currents, with a breakdown voltage of up to 3000V.

Made from high-quality materials, it handles dynamic loads up to 610 kN and static loads up to 620 kN, with a reference speed of 2800 RPM. The brass cage ensures smooth operation and durability under high stress.

The C3 radial clearance allows for thermal expansion, making it suitable for high-speed machinery. The insulation coating (SQ77) provides electrical resistance over 2000 MΩ, protecting against stray currents.

Ideal for electric motors, generators, or wind turbines where electrical insulation is crucial. Compliant with RoHS and REACH standards, it’s a reliable choice for industrial applications. Weighing 14.84kg, it’s robust yet manageable for installation.
