Product Description

The NTN Radial Ball Bearing: 6215 is a ceramic insulated radial ball bearing from NTN, featuring a metric system of measurement and the bearing industry number 6215. This open-type bearing has a 75 mm bore, 130 mm OD, and 25 mm width, with an alloy steel ring (MPN 7MC3-6215C3).

Frequently Asked Questions

What is the NTN 6215 ceramic insulated radial ball bearing used for?

The NTN 6215 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 variable-frequency drive applications in industrial machinery, pumps, and compressors where electrical arcing across bearings must be avoided.

What are the specifications of the NTN 6215 bearing?

The NTN 6215 bearing has a 75 mm bore, 130 mm OD, and 25 mm width. It is an open-type, metric bearing with an alloy steel ring and ceramic insulation. The manufacturer part number is 7MC3-6215C3, and the bearing industry number is 6215. It is designed for radial loads in electric motor applications.

Where to buy the NTN 6215 bearing worldwide?

You can source the NTN 6215 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 across multiple regions.

How to select the correct NTN 6215 bearing for an application?

To select the correct NTN 6215 bearing, verify the shaft diameter matches the 75 mm bore and the housing fits the 130 mm OD. Ensure the 25 mm width aligns with your space constraints. For electric motor use, confirm ceramic insulation is required to block electrical currents. Always check the NTN part number 7MC3-6215C3 for exact specifications.
