1．轴承代用的原则滚动轴承有如下特点:同一类型的轴承内径尺寸相同时,随着直径系列的递增,其外径和宽度也相应增大,轴承的额定动载荷和额定静载荷也随着提高;外径尺寸相同时,随着直径系列的递增,其内径却随着变小,宽度相应增大,轴承额定动载荷和额定静载荷也相应增大。对同一 1. The principle of bearing substitution Rolling bearing has the following characteristics: the same type of bearing inner diameter of the same size, with the increasing diameter series, the corresponding increase in diameter and width, the bearing dynamic load rating and rated static load also increased; With the same diameter size, with the increasing diameter series, but with its smaller diameter, the corresponding increase in width, the bearing dynamic load rating and rated static load also increased accordingly. The same
