六十一、滚动轴承(下称轴承)有哪些种类?怎样从代号中识别?轴承是按其能承受负荷方向(向心、推力)、滚子_形状(球、圆柱、圆锥……),滚子列数(单列、双列)来分类的。在我国现用的轴承分十类,以轴承代号中右起第四位数字来表示。规定代号0为向心球轴;1为向心球面球轴承;2为向心短圆柱滚子轴承;3为向心球面滚子轴承;4长圆柱滚子轴承或滚针轴承;5为螺旋滚子轴承;6为向心推力球轴承;7为
Sixty-one, what are the types of rolling bearings (hereinafter referred to as bearings) and how to identify it from the code? Bearings are according to their load direction (centripetal thrust), roller shape (ball, cylinder, cone ...) Sub-columns (single-column, double-column) to sort. Bearing in our country is divided into ten categories to the right bearing code from the fourth figure to represent. Code 0 for the centripetal ball axis; 1 for the radial ball bearings; 2 for the radial cylindrical roller bearings; 3 radial spherical roller bearings; 4 long cylindrical roller bearings or needle roller bearings; 5 for the spiral Roller bearings; 6 to the heart thrust ball bearings;
