1 Scope This International Standard specifies the tolerances, structural elements and test methods for one-piece flanged thin-walled bushings with outer diameters D0-250 mm and flangeless thin-walled bushings with outer diameters D0-500 mm. However, due to the structural design changes, it is impossible to propose a uniform bearing size standard. In line with this standard bearings are mainly used for reciprocating engines, and by the steel back and its inside or
