Шарики по ГОСТу 3722–81 изготавливаются из хромоуглеродистой стали ШХ15 с термической обработкой диаметром до 45 мм твердость 62…66 НRС, от 45 мм твердость 60…66 НRС.
Шарики могут изготавливаться и другой твердостью и из других сталей: нержавеющая сталь 95Х18 обозначается после диаметра буквой Ю; сталь 8Х4В9Ф2-Ш; сталь кремнемолибденовая 55СМ5ФА; сплав ВК-8.
Шарики применяемые в подшипниках перед обозначением диаметра дополняются буквой Н.
ГОСТ 3722-81 установлено 10 степеней
точности шариков, обозначаемых в порядке снижения
точности цифрами: 3,5,10,16,20,28,40,60,100,200.
