自動調心滾珠軸承

概要

外輪的軌道面為球面,其曲率中心與軸承中心一致。

因此, 內輪、滾珠、保持器可以在軸承中心周圍自由旋轉,具有調心性。

適於軸和軸承座對中心困難、軸易出現撓曲的傳動軸等用途。

因為接觸角小 ,所以軸向負荷能力也小。一般使用沖壓保持器。

自動調心滾珠軸承的允許調心角,在普通負荷情況下,大約為0.07~0.12弧度(4-7度)。

會根據軸承周圍相關的安裝尺寸,也有達不到這種調心角度的特殊情況,請務請注意。

 

特徵

適用於軸與外殼難以對準的應用,例如軸容易偏斜的傳動軸。

應用實例

減速器


FAQs

 

answersSelf-aligning ball bearings suit light loads with high-speed rotation, while spherical roller bearings suit heavy loads with low-speed rotation.

 

answersThe recommended grease for self-aligning ball bearings depends on usage conditions.
You can use the selection criteria for finding suitable grease for deep groove ball bearings with self-aligning ball bearings as well.

 

answersBecause they have small contact angles, self-aligning ball bearings have extremely limited capacity for thrust loads.
Please consider using thrust bearings with aligning seats if thrust loads are expected.
