Product Description

The NTN Radial Ball Bearing: 6315 is a ceramic insulated radial ball bearing with a metric system of measurement. It features a 75 mm bore, 160 mm OD, and 37 mm width, with an alloy steel ring. The bearing industry number is 6315, and the manufacturer part number is 7MC3-6315C3.

Frequently Asked Questions

What is the NTN 6315 ceramic insulated bearing used for?

The NTN 6315 ceramic insulated radial ball bearing is used in electric motors and generators to prevent electrical pitting caused by stray currents. Its ceramic coating on the outer diameter insulates the bearing, extending service life in industrial machinery, pumps, and compressors where shaft voltages occur.

What are the specifications of the NTN 6315 bearing?

The NTN 6315 bearing has a 75 mm bore, 160 mm outer diameter, and 37 mm width. It is an open, metric radial ball bearing with an alloy steel ring and ceramic insulation. The bearing industry number is 6315, and the manufacturer part number is 7MC3-6315C3.

Where to buy NTN 6315 bearings worldwide?

You can source NTN 6315 bearings 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 components for demanding applications.

How to select the right NTN 6315 bearing for an electric motor?

To select the correct NTN 6315 bearing, verify the shaft diameter (75 mm bore), housing bore (160 mm OD), and width (37 mm). Confirm the motor's voltage and frequency to ensure the ceramic insulation rating matches. For NTN bearings, always check the manufacturer part number 7MC3-6315C3 for exact fit.
