71900A(AC)系列高速角接触球轴承(型号尺寸表)

1、.71900A(AC)系列高速角接触球轴承宁波百川轴承角接触球轴承可同时承受径向负荷和轴向负荷。能在较高的转速下工作。接触角越大，轴向承载能力越高。高 精度和高速轴承通常取15 度接触角。在轴向力作用下，接触角会增大。单列角接触球轴承：只能承受一个方向的轴向负荷，在承受径向负荷时，将引起附加轴向力。并且只能限制轴 或外壳在一个方向的轴向位移。成对双联球轴承：成对双联安装，使一对轴承的外圈相对，即宽端面对宽端面 窄端面对窄端面。这样即可避免引起附加轴向力，而且可在两个方向使轴或外壳限制在轴向游隙范围内。2. 产品结构 7000C型(15) 7000AC型(25) 7000B(40).7200C(
