7219/DB/DF/DT 一）滑動TIMKEN軸承的類型和特性I滑動TIMKEN軸承的類型或稱為徑向滑動TIMKEN軸承， 1．滑動TIMKEN軸承依照接受載荷分為：向心滑動TIMKEN軸承。主要接受徑向載荷；推力滑動TIMKEN軸承，主要接受軸向載荷。2．滑動TIMKEN軸承適用于低速、高精度、重載和結構上要求剖分的場所。與滑動TIMKEN軸承相比，滾動TIMKEN軸承為滾動摩擦。其接觸面小（球TIMKEN軸承為點接觸、滾子TIMKEN軸承為線接觸）摩擦系數小、發熱少；磨損少、精度堅持性好；適宜較高的轉速下運轉。但承載能力稍差、抗振性較差。3．向心滑動TIMKEN進口軸承 向心滑動TIMKE
