RB交叉滾子軸承

RB系列交叉滾子軸承(內(nèi)圈整體、外圈分體)

RB型此型號為交叉滾子軸承的基本型。外圈被分為兩片,內(nèi)圈為整體結(jié)構(gòu),它最適合用于要求內(nèi)圈旋轉(zhuǎn)精度的場合。

交叉圓柱滾子軸承的結(jié)構(gòu)分為外圈分體、內(nèi)圈整體;外圈整體、內(nèi)圈分體和外圈內(nèi)圈均為整體三種形式,滾動體為圓柱滾子,互為90°垂直排列在V型滾道中,滾子之間由隔離塊隔開。這種結(jié)構(gòu)使得單個軸承就可以承受軸向載荷、徑向載荷和傾覆力矩等各方面的載荷。同時,由于外形尺寸被最大的微型化,且軸承又具有很高的剛性和旋轉(zhuǎn)精度以及復(fù)合承載能力,所以最適合于工業(yè)用機器人的關(guān)節(jié)部或旋轉(zhuǎn)部、加工中心的旋轉(zhuǎn)工作臺、機械手旋轉(zhuǎn)部、精密旋轉(zhuǎn)工作臺、醫(yī)療機器、測量儀等場合應(yīng)用。
