NKE Electrically Insulated Single Row Cylindrical Roller Bearing NU213-E-TVP3-SQ77

NKE Electrically Insulated Single Row Cylindrical Roller Bearing NU213-E-TVP3-SQ77

The NU213-E-TVP3-SQ77 is an electrically insulated cylindrical roller bearing with a 65mm bore and 120mm outer diameter, designed to prevent electrical currents from damaging machinery. Its outer ring features a special coating (SQ77) with a breakdown voltage of 1000-3000V, ideal for high-voltage environments.

This bearing handles dynamic loads up to 122kN and spins smoothly at speeds up to 6300 RPM. The polymer cage reduces friction and wear, while the normal radial clearance ensures reliable performance under typical operating conditions.

The insulation layer is over 0.125mm thick, providing electrical resistance above 2000 MΩ. It’s compliant with RoHS and REACH standards, making it safe for industrial use.

Weighing 1.05kg, it’s a sturdy choice for electric motors, generators, or wind turbines where electrical insulation is crucial. The design also allows for easy replacement in existing systems.
