双列角接触球轴承

1、双列角接触球轴承（32*、33*、5200、5300系列，ZZ, 2RS型）双列角接触球轴承性能特点、分类、型号对照、负荷、尺寸参数表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。因其内外圈的滚道可在水平轴线上有相对位移，所以可以同时承受径向负荷和轴向负荷一一联合负荷（单列角接触球轴承只能承受单方向轴向负荷，因此一般都常采用成对安装）。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。若是成对双联安装，使一对轴

2、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。角接触球轴承有：7000C型（8= 15° ）、7000AC型（25° ）和7000B（= 40° ）几种类型。该种轴承的锁口在的外圈上，一般内外圈不能分离，可承受径向和轴向的联合载荷以及一个方向的轴向载荷。承受轴向载荷的能力由接触角决定，接触角大，则承受轴向载荷的能力高。该种轴承能限制轴或外壳在一个方向的轴向位移角接触球轴承因其内外圈的滚道可在水平轴线上有相对位移，所以可以同时承受径向负荷和轴向负荷一一 联合负荷（单列角接触球轴承只能承受单
