Les roulements fonctionnent dans des conditions de frottement continu, \u00e0 des vitesses de rotation \u00e9lev\u00e9es et sous de fortes charges m\u00e9caniques, ce qui rend l'\u00e9valuation de leur duret\u00e9 cruciale pour garantir leur durabilit\u00e9 et leur longue dur\u00e9e de vie.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Les fabricants utilisent <strong>essais de duret\u00e9 des
