BS ISO 3547-2:2017 pdf download – Plain bearings — Wrapped bushes Part 2: Test data for outside and inside diameters
This document specifies the test data for outside and inside diameters of wrapped bushes made of mono and multi-layer bearing material for plain bearing applications. It also specifies test designations.
Since the wall thickness of the bush is measured in the free condition, no special test data are required for this on the drawing (see ISO 3547-5 and ISO 3547-6).
NOTE Depending on the manufacturing method, the back of the bushes can show isolated light depressions and, similarly, bushes with lubrication holes, grooves and bore indentations can show distortion. It is therefore suggested to measure the wall thickness away from these areas.

5 Presentation of data on drawing
The drawing should show either
— the outside diameter, D o , and the wall thickness, s 3 , or
— the outside diameter, D o , and the inside diameter, D i .
Wall thickness, s 3 , and inside diameter, D i , shall not be specified together on the same drawing. See Figure 1. BS ISO 3547-2 pdf download.
