NTN Bearing Corp. of America added ceramic ball bearings for electric motor applications as its newest product offering.

NTN’s new series of ceramic ball bearings was specifically designed to prevent electrical arcing in a variety of applications, the company says.

“We are elated to offer yet another high-quality bearing solution to our customers,” says James Misch, director of marketing and technical services at NTN. “The electric motor industry in particular presents numerous challenges due to the nature of the industry and the potential exposure of bearings to stray electric currents. This new product innovation is designed to combat multiple potential failure modes, giving our customers peace of mind that their operations will not be impacted by unexpected downtime.”

NTN says its ceramic ball bearings are robustly designed with steel rings and cages but feature ceramic balls instead of standard steel balls. They are useful in a number of applications across a variety of industries, the company adds.

Due to ceramic being nonconductive, NTN says the material is ideal for applications where stray currents are present.

NTN’s ceramic ball bearing offering comes with two shields, electric motor grease and C3 clearance as standard. The company says it stocks some of the most common bearing sizes while offering bearings with bore diameters up to 65 mm.
