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.

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.

7.1 Description
This test is applicable to D up to 180 mm.
o
The test rig consists of a base on which the two parts of the checking block are mounted (see ISO 3547-5).
A setting plug is inserted in the checking block and the two halves of the checking block are pressed
towards one another using the given checking load, Fch, and the indicator reading set.
The setting plug is then removed and replaced by the bush to be checked, and the checking load reapplied.
After the bush has been inserted, the distance, z, between the two halves of the checking block changes
under checking load F and the distance indicator reading, Δz, is recorded.

From this, D can be calculated.
o
Flanged bushes may be checked either before or after flange forming at the option of the manufacturer.
7.2 Calculation basis
7.2.1 Elastic reduction, v, of outside diameter, D

The elastic reduction, v, of the outside diameter, D , is the difference between D under zero load and the

bush conforms properly to the surface of the test housing and that the results in the elastic reduction, v,
