NTN Releases Ceramic Ball Bearings for Electric Motor Applications
November 17, 2021
NTN Bearing Corporation of America is pleased to announce ceramic ball bearings for electric motor applications as its latest product offering. NTN’s new series of ceramic ball bearings has been specifically designed to prevent electrical arcing in a variety of applications.
“We are elated to offer yet another high-quality bearing solution to our customers,” exclaimed James Misch, director of marketing and technical services, 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.”
Robustly designed with steel rings and cages but featuring ceramic balls instead of standard steel balls, NTN ceramic ball bearings are useful in many different applications found within a variety of industries including the electric motor industry. Due to ceramic being nonconductive, 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. We stock some of the most common bearing sizes while offering bearings with bore diameters up to 65mm, and our entire offering has ISO standard dimensions for easy interchangeability. Additionally, the ceramic material of these bearings generate less heat allowing longer service intervals than the steel ball equivalents. NTN’s ceramic ball bearings offer a cost-effective solution to combat stray electric currents and other harsh operating conditions.
