Bearing (mechanical) Wikipedia

The first patent for a radial style ball bearing was awarded to Jules Suriray, a Parisian bicycle mechanic, on 3 August 1869.The bearings were then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris-Rouen, in November 1869.. In 1883, Friedrich Fischer, founder of FAG, developed an approach for milling and grinding balls of equal size and exact

Abstract Effect of Disorder Induced by Ball Milling on

Prepared carbon xerogel blocks were crushed in mortar before ball milling for 15 min, 45 min and 4 hours. A thick slurry was made from the ball milled powder and PVDF was mixed as binder in the ratio of 91 in N-methylpyrolidone used as solvent. This slurry was then coated on SS foil (100 micron thick) and used as working electrode.

The effects of ball milling on the hydrogen sorption kinetics and microstructure of Zr0.8Ti0.2Co have been systematically studied. Kinetic measurements show that the hydrogenation rate and amount of Zr0.8Ti0.2Co decrease with increasing the ball milling time. However, the dehydrogenation rate accelerates as the ball milling time increases.
