CRBH交叉滾子軸承

CRBH系列交叉圓柱滾子軸承(內(nèi)外圈整體型、超薄)

CRBH列交叉圓柱滾子軸承,此型號是超薄型的RU系列軸承,由于采用了超薄設(shè)計(jì)而且外圈和內(nèi)圈沒有安裝孔,安裝時(shí)需要法蘭和支撐座固定。另外,由于外圈和內(nèi)圈均為整體結(jié)構(gòu),安裝對性能沒有影響,因此能夠獲得穩(wěn)定的旋轉(zhuǎn)精度和扭矩,適用于外圈和內(nèi)圈旋轉(zhuǎn)但有尺寸小型化要求的場合。

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(gè)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(shí),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(jī)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(jī)械手旋轉(zhuǎn)部、精密旋轉(zhuǎn)工作臺、醫(yī)療機(jī)器、測量儀等場合應(yīng)用。
