Sets out the main dimensions and tolerances for thin-walled flanged half bearings used in reciprocating machinery. Main dimensions and tolerances are fixed for a series of thin-walled flanged half bearings suitable for housings having inside diameters from 40 to 250 mm. Covers references, definitions, symbols, main dimensions and tolerances, method of checking peripheral length, dimensions and tolerances of the relief of the flanges, minimum height (and width) of transition, dimensions and tolerances of grooves on the flange face and dimensions and tolerances of oil holes on the flange face. Several tables and figures are given.
