The latest design engineering update from the Tribology Group of ESDU International is the newly issued Data Item (No. 96015) "Design and Material Selection for Dry Rubbing Bearings".

The Data Item describes the use of the ESDU computer program A9615 for the selection of materials for dry rubbing bearings (Plate 15).

Dry rubbing bearings are often the first choice for applications where a film of lubricating fluid cannot be maintained, for example at high or low rotational speeds. They are also used when the ambient conditions are unsuitable for a conventional lubricant or when contamination of the surroundings by the lubricant must be avoided.

The Data Item describes the preparation of input data for the computer program and illustrates the interpretation of the output by means of worked examples. The program can also be used to analyse the performance of a dry rubbing bearing of known material.

Plate 15 The new ESDU Data Item helps with the selection of materials for use in a wide range of dry rubbing bearing applications, including aircraft undercarriage bearings

The program is supplied with full source code (FORTRAN 77) and a database that incorporates the results of tests on polymer based bearing materials carried out at the National Centre of Tribology. Data on bearing materials based on bulk carbon/graphites are on metals with solid lubricant additions and also included. If required, the program can be used with alternative databases, the preparation of which is explained in the new ESDU Data Item.
