ISO 3547-2:2017 specifies the test data for outside and inside diameters of wrapped bushes made of mono and multi-layer bearing material for plain bearing applications. It also specifies test designations. Since the wall thickness of the bush is measured in the free condition, no special test data are required for this on the drawing (see ISO 3547‑5 and ISO 3547‑6). NOTE Depending on the manufacturing method, the back of the bushes can show isolated light depressions and, similarly, bushes with ...view more

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 Do = 250 mm and without flange up to an outside diameter of Do = 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 ...view more
