Ceramic Ball Bearing Performance Tests



A New Ball Bearing

INTRODUCTION:
Want to save a *million barrels of petroleum a day by simply changing to a more
efficient ball bearing in machinery? Sounds too good to be true, but it s possible with
new materials available today.
Tribology The science of friction and wear.
If we look at the surface finish of a metal ball or race very closely, peaks and valleys
appear over these surfaces. It is the job of fluid lub ....etc

ceramic cutting tool materials ppt

In the context of machining, a cutting tool or cutter is any tool that is used to remove material from the workpiece by means of shear deformation. Cutting may be accomplished by single-point or multipoint tools. Single-point tools are used in turning, shaping, planing and similar operations, and remove material by means of one cutting edge. Milling and drilling tools are often multipoint tools. Grinding tools are also multipoint tools. Each grain of abrasive functions as a microscopic single-point cutting ed ....etc

ceramic fasteners ppt

Stock Ceramic Fasteners

Stock ceramic fasteners from Ceramco are the solution for applications in which metal alloy or plastic fasteners fail, or simply do not possess the properties demanded by the environment in which they must exist. The following are just a few of the properties and characteristics of Ceramco s stock ceramic machine screws, nuts, bolts and washers:

High Temperature Stability Up to 2,000 C
Corrosion Protection Impervious to chemical attack, oxidation and UV light degradation
Wear Resistant Stand ....etc

A Ceramic Hybrid Ball Bearing is a precision bearing in which one or all of its components are made of ceramic elements from silicon nitride. Silicon nitride is a highly processed silica and ceramic material, similar to the heat absorbing, highly resilient tiles on the Space Shuttle. These tiles are used to line the heat shield of the Space Shuttle, as they protect it from the 2500 plus degrees F. extremes of re-entry into the earth's atmosphere. The use of Ceramics for bearing components results in a far superior product over traditional all s ....etc

Until now brake discs have been made up of grey cast iron, but these are heavy which reduces acceleration, uses more fuel and has a high gyroscopic effect.

Ceramic disc brake weigh less than carbon/carbon discs but have the same frictional values with more initial bite and cost a fraction of price. Carbon /carbon discs are used only in Formula 1 racing cars etc, because it is so expensive. More over ceramic brake discs are good even in wet conditions which carbon / carbon disc notoriously fails to do.

But comparing their weight, you will ....etc
