Welcome To Neale Consulting Engineers

We specialize in tribology consultancy services, including analysis of engineering components, machines and systems.
It is our belief that Tribology is fundamental to nearly every aspect of Mechanical Engineering.

Services We Offer

Design Evaluation

We offer a design evaluation service whereby the 'fitness for purpose' of mechanisms and components are assessed - helping to prevent future failure and malfunction.

Failure Analysis

We have expertise in an extensive range of mechanical and tribological failures. These include: Gear failures Plain bearing failures, Rolling bearing failures and Seal failures.

Engineering Training

We have distilled our extensive experience of machine operation and failure into practical training courses. These are run as open courses for engineers from several companies, or may be specifically tailored courses in-house to individual companies.


We are often required to act as expert witnesses for litigation purposes, both in the UK and overseas. Cases range from patent infringements and project disputes between companies to litigation arising from international disasters.

Analysis & Calculation

We regularly complete detailed spreadsheet and finite element analyses of machine elements, bearings and structures. A service that is invaluable in both determining failure root causes and evaluating new designs.


We have completed consulting projects all over the world. We regularly travel to international locations to bring our expert consultancy services to those who need it most.

The Tribology Handbook

The De-Facto Tribology Reference

Ever since it was first published 20 years ago, The Tribology Handbook has been the standard reference 'Bible' for generations of engineers the world over.

The Book's Primary Aim

It aims to provide instant access to essential information on the performance of tribological components, and is aimed particularly at designers and engineers in industry.

For Machine Designers and Tribologists

Designers of machines should also find the contents of the book extremely helpful, because they provide an atlas of component performance.
