雙列調(diào)心球軸承
調(diào)心球軸承特別適用于因安裝不當或軸彎曲引起偏斜的工作場合，當調(diào)心球軸承承載能力（特別是軸向載荷）不足時，可選用具有相同調(diào)心性能的球面滾子軸承。我們公司備有各種系列和結(jié)構(gòu)的此類軸承，可供選擇，這類軸承采用沖壓保持架或聚酰胺保持架，軸承代號帶后綴 G 表示帶聚酰胺保持架。

注意：
　　在一般使用條件下，12 系列和 22 系列軸承允許傾斜角為 2.5°，13 系列和 23 系列軸承允許傾斜角為 3°，當軸承在傾斜的條件下使用時必須保證軸承和周圍零件有足夠間隙；當轉(zhuǎn)速升高時，傾斜的軸承噪聲有增大的趨勢。由于噪聲的限制，軸承實際傾斜角可能比傾斜角小很多；對帶圓錐內(nèi)孔的軸承，安裝后很難準確測量軸承游隙，因此帶圓錐內(nèi)孔的軸承安裝需要一定經(jīng)驗和技術(shù)；帶聚酰胺保持架軸承工作溫度應低于 120℃。

Self-aligning ball bearing to be suitable specially in installs improperly or the axis causes the oblique work situation ,when self-aligning ball bearing load capacity(specially the axial load) insufficiency,in this condition can select the ball bearing which has the coherence self-aligning performance.Our company has each kind of series and structure bearing for your choice,this kind of bearing uses the ramming retainer or polyamide retainer,the bearing code number suffix G stａnd for polyamide retainer.

Under the general exploitation conditions,12 series and 22 series bearing permission angle of bank is 2.5 degrees,13 series and 23 series bearing permission angle of bank is 3 degrees,when the bearing is inclining completely,under this condition uses must guarantee the bearing and periphery the components has the enough gap,when the rotational speed elevates,the inclined bearing noise has the enlargement tendency,as a result of noise limit,bearing actual angle of bank more smaller than the biggest angle of bank,to circular cone in hole bearing,after the installment,is very difficult measurement bearing windage correctly,therefore in the circular cone in hole bearing installment needs certainly experience and technology ,polyamide retainer bearing work temperature to be lower than 120 degrees.
