Product Description

The NTN 6319 is a metric ceramic insulated radial ball bearing with an open design, featuring a 95 mm bore, 200 mm OD, and 45 mm width. It is constructed with an alloy steel ring and carries the manufacturer part number 7MC3-6319C3.

Frequently Asked Questions

What is the NTN 6319 ceramic insulated radial ball bearing used for?

The NTN 6319 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 insulates the bearing, protecting against stray currents that can cause fluting or premature failure in industrial machinery.

What are the specifications of the NTN 6319 bearing?

The NTN 6319 is a metric ceramic insulated radial ball bearing with an open design. It has a 95 mm bore, 200 mm OD, and 45 mm width. The ring is made of alloy steel, and the bearing industry number is 6319. The manufacturer part number is 7MC3-6319C3. It is designed to prevent electrical damage in motor applications.

Where to buy the NTN 6319 bearing worldwide?

You can source the NTN 6319 ceramic insulated radial ball 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 for industrial applications.

How to select the correct NTN 6319 bearing for an application?

To select the correct NTN 6319 bearing, verify the shaft diameter (95 mm bore), housing bore (200 mm OD), and width (45 mm). Confirm the operating temperature and electrical insulation requirements. The open design suits applications without contamination risk. For sealed or shielded variants, consult NTN specifications. Always match the bearing industry number 6319.
