Spherical Roller Bearings
Symmetrical spherical roller bearing is a kind of bearing with double raceways of inner ring and spherical raceway of outer ring, and the barrel shaped rollers was assembled between them. Spherical roller bearing has double-row rollers, that mainly take the radial load, it also can take the axial load at the same time. This kind of bearing is specially suitable to work in the heavy load and shaking load condition for the radial load capacity. But is can not take the pure axial load. The bearing has better symmetrical capacity, that can compensate the error of coaxiality for the spherical raceway.
曲面滾子滾針軸承
球體滾子的滾柱滾針滾動軸承是在有二條絲桿螺母的內圈和絲桿螺母為球體的南側相互,裝配著鼓形滾子的的滾柱滾針滾動軸承。 球體滾子的滾柱滾針滾動軸承有兩列滾子,重點能所能必須徑向趨勢,而且還能能所能必須某一趨勢的軸上承載。有高的徑向承載特性,尤其適用人群于方法重載或振動幅度大承載下的工作,但是不能能所能必須純軸上承載。純虛函數的滾柱滾針滾動軸承南側絲桿螺母是球體形,故其調性情能較好,能賠償同軸度粗差。
