This part of ISO3548 specifies tolerances, design features, and test methods for thin-walled half bearings with integral flange up to an outside diameter of Do=250mm and without flange up to an outside diameter of Do=500mm. Due to the variety of design, it is, however, not possible to standardize the dimensions of the half bearings.
Half bearings according to this part of ISO3548 are predominantly used in reciprocating machinery and consist of a steel backing and one or more bearing metal layers on the inside.
In reciprocating machinery, flanged half bearings can be used in connection with half bearings without flange.
Alternatively, to serve as a flanged half bearing, it is possible to use a half bearing without flange together with two separate half thrust washers according to ISO6526; or a half bearing with assembled flanges.
NOTE All dimensions and tolerances are given in millimetres.
