Frequently Asked Questions

What is the NTN 6330 ceramic insulated radial ball bearing used for?

The NTN 6330 ceramic insulated radial ball bearing is used in electric motors and generators to prevent electrical pitting damage. Its ceramic coating on the outer or inner ring blocks stray currents, making it ideal for variable-frequency drive (VFD) applications in industrial machinery, pumps, and compressors.

What are the specifications of the NTN 6330 bearing?

The NTN 6330 is a metric ceramic insulated radial ball bearing with a 150 mm bore, 320 mm OD, and 65 mm width. It has an open design, an alloy steel ring, and manufacturer part number 7MC3-6330C3. The bearing industry number is 6330, and it is designed for high-voltage isolation.

Where to buy the NTN 6330 bearing worldwide?

You can source the NTN 6330 bearing worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine NTN bearings to customers across multiple industries.

How to select the correct NTN 6330 bearing for an application?

To select the correct NTN 6330 bearing, verify the shaft diameter (150 mm bore), housing bore (320 mm OD), and width (65 mm). Confirm the operating temperature and voltage conditions to ensure the ceramic insulation rating matches your motor or generator. Always cross-reference the manufacturer part number 7MC3-6330C3 for exact fit.
