Frequently Asked Questions

What is the NTN 6324 ceramic insulated radial ball bearing used for?

The NTN 6324 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 from passing through the bearing, extending service life in variable-frequency drive (VFD) applications.

What are the specifications of the NTN 6324 bearing?

The NTN 6324 is a metric ceramic insulated radial ball bearing with a 120 mm bore, 260 mm OD, and 55 mm width. It has an open design, an alloy steel ring, and manufacturer part number 7MC3-6324C3. The bearing industry number is 6324.

Where to buy the NTN 6324 bearing worldwide?

3G Electric supplies the NTN 6324 ceramic insulated radial ball bearing worldwide. As a global industrial equipment distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time.

How to select the correct NTN 6324 bearing for an application?

To select the correct NTN 6324 bearing, verify the shaft diameter (120 mm bore), housing bore (260 mm OD), and required width (55 mm). Confirm the open design suits your lubrication method. For VFD motors, the ceramic insulation prevents electrical damage. Always match the NTN part number 7MC3-6324C3.
