NSK Ceramic-Coated Ball Bearings

We know that ceramic bearings are more resistant to corrosion, lighter in weight, nonconductive, and can operate in temperatures of up to 1,800 degrees Farenheit. This range of characteristics make ceramic bearings versatile and valuable.

Ceramic bearings additionally offer up less noise and vibration compared with steel ball bearings.

Today, we’re going to do an overview of a specific product, the ceramic-coated ball bearings offered by trusted bearings manufacturer, NSK.

Product Overview

NSK has a major stake in power generation from wind turbines, and the growing demand for innovative technology in that sector has to do with bearing innovation.

As a major supplier, NSK is forefront in providing bearing solutions that deliver outstanding levels of reliability, heat resistance, and long life.

So, if the bearing application you’re working on produces a high-rate of bearing damage, and/or machine failures caused by electrical corrosion – in the generators of wind turbines, for example – NSK’s ceramic-coated ball bearings may be the solution to your problem.

These ceramic-coated ball bearings have high insulation resistance, and prevent deterioration by electrical corrosion.

What starts out as steel ball bearings are plasma sprayed, ensuring the ceramic is properly bonded to the bearing’s steel. Then, acrylic resin is used to further seal the coating.

Features and Benefits

Ceramic-coated steel bearing ring

Thickness of the ceramic coating is optimized

NSK’s plasma spray process ensures long-term durability

Insulation capability is optimized by the acrylic resin layer which seals the coating

Cost-efficiency is maximized due to increased bearing life

High insulation resistance

Lesser cost than hybrid bearings (Due to the elimination of costly manufacturing processes pure ceramic balls

require.)

No special preparation of the housing bore is needed

The thermal conductivity is unaffected between bearing and housing

Applications

Electric Motor

Electric Drive

Wind Turbine

Generator

Traction Motor
