Nine Star JXKJ Ceramic-Coated Ball Bearings

2015-10-23

We discussed the main three different types of ball bearing materials in an earlier post.

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, Nine Star.

Product Overview

Nine Star JXKJ 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, Nine Star JXKJ 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 – Nine Star’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
Nine Star’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
