Frequently Asked Questions

What is the NTN 6313 ceramic insulated radial ball bearing used for?

The NTN 6313 ceramic insulated radial ball bearing is used in electric motors and generators to prevent electrical pitting damage. Its ceramic insulation blocks stray currents, making it ideal for industrial machinery, pumps, and compressors where electrical arcing across bearings must be avoided.

What are the specifications of the NTN 6313 bearing?

The NTN 6313 bearing has a 65 mm bore, 140 mm OD, and 33 mm width. It is an open type with an alloy steel ring, metric system of measurement, and bearing industry number 6313. The manufacturer part number is 7MC3-6313C3. NTN is the OEM brand.

Where to buy the NTN 6313 bearing worldwide?

You can source the NTN 6313 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 6313 bearing for an application?

To select the correct NTN 6313 bearing, verify the bore (65 mm), OD (140 mm), and width (33 mm) match your housing and shaft. Confirm the open type suits your lubrication method. For electric motor use, the ceramic insulation in this NTN bearing prevents fluting damage from stray currents.
