Product Description

The NTN Radial Ball Bearing: 6317 is a ceramic insulated radial ball bearing from NTN, identified by bearing industry number 6317 and manufacturer part number 7MC3-6317C3. This metric bearing features an open design with an 85 mm bore, 180 mm outer diameter, and 41 mm width, constructed with an alloy steel ring.

Frequently Asked Questions

What is the NTN 6317 ceramic insulated radial ball bearing used for?

The NTN 6317 ceramic insulated radial ball bearing is used in electric motors, generators, and industrial machinery where electrical arcing can damage standard bearings. Its ceramic insulation prevents current passage through the bearing, extending service life in variable-frequency drive applications.

What are the specifications of the NTN 6317 bearing?

The NTN 6317 bearing has an 85 mm bore, 180 mm outer diameter, and 41 mm width. It is an open, metric bearing with an alloy steel ring. The bearing industry number is 6317, and the manufacturer part number is 7MC3-6317C3. It is a ceramic insulated radial ball bearing.

Where to buy the NTN 6317 bearing worldwide?

You can source the NTN 6317 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 6317 bearing for an application?

To select the correct NTN 6317 bearing, verify the shaft diameter matches the 85 mm bore and housing fits the 180 mm OD. Confirm the 41 mm width and open design suit your mounting. For electrical insulation needs, the ceramic coating on this NTN bearing prevents fluting damage in motor applications.
