Frequently Asked Questions

What is the NTN Cylindrical Roller Bearing 313 used for?

The NTN Cylindrical Roller Bearing 313 is used in industrial machinery that requires high radial load capacity and electrical insulation. Its ceramic insulated design prevents electrical arcing through the bearing, making it suitable for motors, generators, and traction drives where stray currents can cause damage.

What are the specifications of the NTN 7MC3-NU313EGRBC3 bearing?

The NTN 7MC3-NU313EGRBC3 is a metric cylindrical roller bearing with a 65 mm bore, 140 mm OD, and 33 mm overall width. It features alloy steel rings, a brass cage, and an NU design. The bearing industry number is 313, and it is a ceramic insulated type.

Where to buy NTN ceramic insulated bearings worldwide?

You can source the NTN 7MC3-NU313EGRBC3 ceramic insulated 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.

How to select the correct NTN cylindrical roller bearing for an application?

To select the correct NTN cylindrical roller bearing, match the bore, OD, and width to your housing and shaft dimensions. For electrical insulation, choose a ceramic coated version like the NU313. Verify the cage material (brass in this model) suits your operating temperature and speed requirements.
