ISO 3548-1:2014规定了带整体法兰（外径小于等于250 mm）和不带法兰（外径小于等于500 mm）的薄壁半轴承的公差、设计特征和试验方法。然而，由于设计的多样性，无法标准化半轴承的尺寸。根据ISO 3548-1:2014，半轴承主要用于往复式机械，由钢背衬和内部的一个或多个轴承金属层组成。

ISO 3548-1:2014 specifies tolerances, design features, and test methods for thin-walled half bearings with integral flange up to an outside diameter of D_o = 250 mm and without flange up to an outside diameter of D_o = 500 mm. Due to the variety of design, it is, however, not possible to standardize the dimensions of the half bearings. Half bearings according to ISO 3548-1:2014 are predominantly used in reciprocating machinery and consist of a steel backing and one or more bearing metal layers on the inside.
