Frequently Asked Questions

What is the NTN 6228 ceramic insulated radial ball bearing used for?

The NTN 6228 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 coating on the outer diameter blocks stray currents, extending bearing life in variable-frequency drive (VFD) applications.

What are the specifications of the NTN 6228 bearing?

The NTN 6228 is a metric ceramic insulated radial ball bearing with a 140 mm bore, 250 mm outer diameter, and 42 mm width. It has an open design with an alloy steel ring. The manufacturer part number is 7MC3-6228C3, and the bearing industry number is 6228.

Where to buy the NTN 6228 bearing worldwide?

You can source the NTN 6228 bearing worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we supply genuine NTN bearings to customers in multiple industries.

How to select the correct NTN 6228 bearing for an application?

To select the correct NTN 6228 bearing, verify that your shaft diameter matches the 140 mm bore and the housing accommodates the 250 mm outer diameter and 42 mm width. Confirm the operating temperature and speed ratings from NTN's catalog. For VFD motors, the ceramic insulation in this NTN bearing prevents electrical damage.
