Frequently Asked Questions

What is the NTN 6230 ceramic insulated radial ball bearing used for?

The NTN 6230 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.

What are the specifications of the NTN 6230 bearing?

The NTN 6230 is a metric open radial ball bearing with a 150 mm bore, 270 mm OD, and 45 mm width. It has alloy steel rings and a ceramic insulation coating. The manufacturer part number is 7MC3-6230C3, and the bearing industry number is 6230.

Where to buy the NTN 6230 bearing worldwide?

You can source the NTN 6230 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 ceramic insulated bearing.

How to select the correct NTN 6230 bearing for an application?

To select the correct NTN 6230 bearing, verify the bore size (150 mm), OD (270 mm), and width (45 mm) match your housing and shaft. Ensure the open design suits your lubrication method. The ceramic insulation is critical for motor applications where electrical arcing is a concern.
