產品詳情
交叉滾子軸承主要特點1、具有出色的旋轉精度
交叉滾子軸承內部結構采用滾子呈90°相互垂直交叉排列,滾子之間裝有間隔保持器或者隔離塊,可以防止滾子的傾斜貨滾子之間相互磨察,有效防止了旋轉扭矩的增加。另外,不會發生滾子的一方接觸現象或者鎖死現象;
2、操作安裝簡化
被分割成2部分的外環或者內環,在裝入滾子和保持器后,被固定在一起,所以安裝時操作非常簡單。
3、承受較大的軸向和徑向負荷
因為滾子在呈90°的V型溝槽滾動面上通過間隔保持器被相互垂直排列,這種設計使交叉滾子軸承就可以承受較大的徑向負荷、軸向負荷及力矩負荷等所有方向的負荷。
4、大幅節省安裝空間
交叉滾子軸承的內外環尺寸被小限度的小型化,特別是超薄結構是接近極限的小型尺寸,并且具有高剛性,所以于工業機器人的關節部位或者旋轉部位、機械加工中心的旋轉工作臺、機械手旋轉部、精密旋轉工作臺、醫療儀器、計量器具、IC制造裝置等廣泛用途。
