Electrically Insulated Single Row Cylindrical Roller Bearings NU 210 ECM/C3HVA3091

Electrically Insulated Single Row Cylindrical Roller Bearings NU 210 ECM/C3HVA3091

The NU 210 ECM/C3HVA3091 is an electrically insulated cylindrical roller bearing, measuring 50mm in bore, 90mm outside, and 20mm wide. It features a special coating that prevents electrical current from passing through, protecting machinery from damage.

With a dynamic load rating of 73.5 kN, it handles heavy radial loads comfortably while maintaining smooth operation at speeds up to 8500 RPM. The machined brass cage provides reliable guidance for the rollers during rotation.

Its insulation coating offers breakdown voltage protection from 1000 to 3000 VDC, making it resistant to electrical arcing. The C3 internal clearance allows for thermal expansion in warmer operating conditions.

This bearing suits electric motors, generators, and other applications where electrical currents could cause damage. It meets RoHS and REACH standards, weighing just over half a kilogram for easy handling.
