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

research paper on ceramic disc brakes

A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a disc in order to create friction that retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary. The energy of motion is converted into waste heat which must be dispersed. Hydraulic disc brakes are the most commonly used form of brake for motor vehicles but the principles of a disc brake are applicable to almost any rotating shaft.
Compared to drum brakes, disc ....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

ABSTRACT
Today s technology is in need for speed, but at the same time, we need safety as well. For safety, we need deceleration to the maximum extent. These two things are moreover contradictory factors. For speed, we need engines of maximum efficiency and for keeping this speed in bounds, we need brakes of latest technology. For coping up with today s speed, new materials are introduced in the manufacture of brakes.
In my seminars, I am introducing to you the ceramic disc brakes. Cast iron is extensi ....etc

A magnetic bearing is a bearing that supports a load using magnetic levitation. Magnetic bearings accept moving parts without physical contact. For example, they are able to levitate a rotating shaft and allow relative movement with very low friction and without mechanical wear. Magnetic bearings withstand the highest speeds of all types of bearings and do not have a maximum relative speed. Passive magnetic bearings use permanent magnets and, therefore, do not require any input power, but are difficult to design beca ....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
