Plain bearings — Thin-walled half bearings with or without flange — Part 1: Tolerances, design features and methods of test

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.
