Frequently Asked Questions

What is the NTN 6220 ceramic insulated radial ball bearing used for?

The NTN 6220 ceramic insulated radial ball bearing is used in electric motors and generators to prevent electrical pitting damage. Its ceramic coating on the outer diameter blocks stray currents, making it ideal for variable-frequency drive applications in industrial machinery, pumps, and compressors.

What are the specifications of the NTN 6220 bearing?

The NTN 6220 is a metric ceramic insulated radial ball bearing with a 100 mm bore, 180 mm OD, and 34 mm width. It features an open design with an alloy steel ring and carries the manufacturer part number 7MC3-6220C3. The bearing industry number is 6220.

Where to buy the NTN 6220 bearing worldwide?

You can source the NTN 6220 bearing through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this metric ceramic insulated radial ball bearing.

How to select the correct NTN 6220 bearing for an application?

To select the correct NTN 6220 bearing, verify the shaft diameter matches the 100 mm bore and housing fits the 180 mm OD. Confirm the 34 mm width and open design suit your mounting. For electric motor applications, the ceramic insulation prevents stray current damage. Always check operating temperature and load ratings.
