Plain bearings — Thin-walled half bearings with or without flange — Part 1: Tolerances, design features and methods of test
滑动轴承.带或不带法兰的薄壁半轴承.第1部分:公差、设计特点和试验方法
This document 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 this document 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 ISO 6526, or a half bearing with assembled flanges.
NOTE All dimensions and tolerances are given in millimetres.
