Frequently Asked Questions

What is the NTN 6328 ceramic insulated radial ball bearing used for?

The NTN 6328 ceramic insulated radial ball bearing is used in electric motors, generators, and other rotating equipment where electrical arcing across the bearing must be prevented. The ceramic insulation protects against stray currents, extending bearing life in industrial applications such as pumps, compressors, and conveyors.

What are the specifications of the NTN 6328 bearing?

The NTN 6328 bearing has a 140 mm bore, 300 mm outer diameter, and 62 mm width. It is an open design with alloy steel rings, metric system of measurement, and bearing industry number 6328. The manufacturer part number is 7MC3-6328C3. It is a ceramic insulated radial ball bearing.

Where to buy the NTN 6328 bearing worldwide?

You can source the NTN 6328 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 supply genuine NTN bearings to industrial buyers globally.

How to select the correct NTN 6328 bearing for an application?

To select the correct NTN 6328 bearing, verify the shaft diameter matches the 140 mm bore and housing fits the 300 mm OD. Confirm the 62 mm width and open design suit your mounting. Ensure the ceramic insulation is required for your motor or generator to prevent electrical damage. Consult NTN specifications for load ratings.
