保持架
圓錐滾子軸承一般采用鋼板沖壓，筐形保持架，但尺寸較大時，亦采用車制實體支柱保持架。
1. 當軸承外徑D≤650mm時，采用鋼板沖壓保持架，保持架后置代號均不標志
2. 當軸承外徑D>650mm時，采用鋼制實體支柱保持架，保持架后置代號不標志
允許角度誤差
當量動載荷
P=Fr KN] 當Fa/Fr≤e時
P=0.4Fr +YFa [KN] 當Fa/Fr>e時
單列圓錐滾子軸承成對使用時（基本外形尺寸可不同），在計算軸承的當量動載荷時，必須計入徑向載荷引起的附加軸向力。單列圓錐滾子軸承的附加軸向力S，可近似按下式計算：S= Fr/2Y
當量靜載荷
單列圓錐滾子軸承
P0=0.5Fr +Y0Fa KN]
若P0<Fr 則取P0=Fr
