Ceramic Balls are mainly used in harsh environments. Their main advantages on steel is that they have a density 40% lower than steel, have 29% lower thermal expansion and are 150% harder. In certain high-speed applications their life is extended hundred times. It is also used as grinding media. 3 main types are-
Stainless steel plates may be positioned using spherical balls (BA parts). Balls allow closer hole alignment than rods, and generate structures which are inherently resistant to twisting. Balls have the disadvantages, however, of being considerably more expensive, harder to assemble, and less flexible with regard to plate spacing.
