所述非金属套与外圈的内周面、内轴的外周面之间的径向间隙小于0.05mm。
所述非金属套与外圈的内周面、内轴的外周面之间的径向间隙小于钢球与外圈的内周面沟槽、内轴的外周面沟槽之间的径向间隙。
一种组合轴连满装球轴承组装工艺，它包括以下几个步骤：
（1）利用压套工装，将非金属套压嵌在轴承外圈的内周面中部。
（2）将轴承内轴穿入外圈与非金属套内孔中，调节内轴位置，使内轴的外周面沟槽与外圈的内周面沟槽位置对应。
（3）将钢球放在轴承外圈与内轴之间空隙外侧，用敲棒敲击钢球，使钢球进入外圈的内周面沟槽和内轴的外周面沟槽之间。
（4）重复步骤（3）将钢球一个一个填入外圈的内周面沟槽和内轴的外周面沟槽之间，至外圈的内周面沟槽和内轴的外周面沟槽内填满钢球。
（5）将密封圈安装在轴承外圈的内周面与内轴的外周面两侧环槽内，完成组合轴连满装球轴承的组装。
