轉臺軸承

YRT轉臺軸承

YRT標準系列

推力-向心組合結構,可同時承受雙向軸向載荷、徑向載荷和傾覆力矩。軸承上均布有安裝孔,可使用螺栓直接對軸承固定;出廠時軸承已加有預載荷,安裝無需調整游隙;YRT轉臺軸承系列適用于轉速較低、運轉周期較短、對剛性和精度要求高的場合,如回轉工作臺、分度頭。


YRT轉臺軸承由一個推力/向心軸圈,一個推力墊圈,兩個滾針保持架組件和一組向心圓柱滾子組成。 座圈和軸圈有均布的安裝用螺釘孔。該型軸承具有高軸向和徑向承載能力。高傾斜剛度和極高的精度。適用于回轉工作臺,卡盤和銑刀頭以及測量和實驗中的軸承配置。該型軸承對與之相配的設備零件的要求也較高。安裝時需控制安裝螺釘的扭緊力矩。

適用范圍:被廣泛應用于精密回轉臺立式磨床、分度頭、滾齒機、銑齒機工件軸等精密裝置。
