Plain Bearings - Thin-Walled Half Bearings with or without Flange - Tolerances, Design Features and Methods of Test - Second Edition
 N 3548

Annotation

This International Standard specifies tolerances, design features and test methods for thin-walled half bearings with integral flange up to an outside diameter of Do of 250 mm and without flange up to an outside diameter of Do of 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 this International Standard 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 may 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 in accordance with ISO 6526; or a half bearing with assembled flanges.

NOTE All dimensions and tolerances are given in millimetres.

Подшипники скольжения - тонкостенная половина подшипников с или без гребня - терпимости, особенностей дизайна и методов теста - второй выпуск

Этот Международный стандарт определяет допуски, конструкционные особенности и методы испытаний для тонкостенных полуподшипников с составным гребнем до внешнего диаметра Делают 250 мм, и без гребня до внешнего диаметра Делают 500 мм. Из-за разновидности дизайна, однако, не возможно стандартизировать размеры полуподшипников.
