钢背半轴承、衬套和垫圈的轴承性能取决于衬里合金的性能和厚度、钢背衬（通常为SAE 1010）的强度和尺寸稳定性以及衬里合金和衬垫之间的粘结强度。本SAE信息报告主要涉及汽车应用中使用的衬里合金的性能，尤其是内燃机的曲轴轴承。

The bearing performance of steel backed half bearings, bushings, and washers is dependent on the properties and thickness of the lining alloy, the strength and dimensional stability of the steel backing (usually SAE 1010) and the strength of the bond between the lining alloy and the backing. This SAE Information Report is primarily concerned with the properties of the lining alloys used in automotive applications, in particular, the crankshaft bearings of the internal combustion engine.
