Silicon nitride ceramics have good shock resistance compared to other ceramics. Therefore, ball bearings made of silicon nitride ceramic are used in performance bearings. A representative example is use of silicon nitride bearings in the main engines of the NASA's Space Shuttle. [28] [29] Since silicon nitride ball bearings are harder than ...
There are several common designs of ball bearing, each offering various performance trade-offs. They can be made from many different materials, including stainless steel, chrome steel, and ceramic (silicon nitride, Si 3 N 4). A hybrid ball bearing is a bearing with ceramic balls and metal races. Angular contact
Silicon nitride bearing balls, in diameters ranging from 1 to 20mm. Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls themselves are commonly referred to as ball bearings. [1] This is an example of a synecdoche.
