Frequently Asked Questions

What is the NTN 6224 ceramic insulated radial ball bearing used for?

The NTN 6224 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 6224 bearing?

The NTN 6224 is a metric ceramic insulated radial ball bearing with a 120 mm bore, 215 mm outer diameter, and 40 mm width. It has an open design with an alloy steel ring, industry number 6224, and manufacturer part number 7MC3-6224C3. The ceramic insulation protects against electrical discharge.

Where to buy the NTN 6224 bearing worldwide?

You can source the NTN 6224 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; we provide competitive pricing and reliable sourcing for this NTN bearing.

How to select the correct NTN 6224 bearing for an application?

To select the correct NTN 6224 bearing, verify the shaft diameter matches the 120 mm bore and housing fits the 215 mm outer diameter. Confirm the 40 mm width and open design suit your mounting. For electrical insulation needs, the ceramic-coated outer ring of this NTN bearing prevents stray current damage in motor applications.
