NTN Megaohm Single Row Cylindrical Roller Bearing 7MC3-NU319EGRBC3

NTN Megaohm Single Row Cylindrical Roller Bearing 7MC3-NU319EGRBC3

The NTN 7MC3-NU319EGRBC3 is a single-row cylindrical roller bearing with a 95mm bore and 200mm outer diameter, designed for heavy-duty applications. Its insulation coating on the outer ring prevents electrical arcing, making it ideal for electric motors.

With a dynamic load rating of 335kN and a static load rating of 385kN, it handles high loads efficiently. The brass cage ensures smooth operation at speeds up to 3100 RPM.

The C3 radial clearance allows for thermal expansion, while the 0.2mm insulation layer offers a breakdown voltage of 1000-3000 VDC. This makes it suitable for environments with electrical currents.

Weighing 7.13kg, it’s robust yet manageable for industrial use. Compliant with RoHS and REACH standards, it’s a reliable choice for machinery requiring electrical insulation.
