I have over 40 years experience in design and application of rolling bearings. Starting with Ransome & Marles Bearing Co. Ltd at Newark on Trent, I took increasing responsibilities in the product technical function as the company evolved into RHP Bearings Ltd and later NSK-RHP Bearings Europe. Experienced in both Industrial and Automotive sectors, and having operated as a senior manager in a European Technogy Centre, I am well qualified to advise on design and productionisation of standard and bespoke bearings.

Support is also offered for the diagnosis of service problems and bearing failures, with the emphasis on seeking a permanent solution.

Since retiring from NSK-RHP ( NSK Europe) in 2001 David I have operated as Mechconsult with clients mostly drawn from small to medium sized engineering companies. Seminars on aspects for rolling bearings have been arranged for several organisations.

Adept at teasing out issues in both Technical Design challenges and also Business Management operations of Technology Centres, and therefore a useful independent facilitator and contributor.

Background information is kept up to date by membership of IMechE Tribology Group Committee and being their user group representative on BSI Technical Committee MCE/7 rolling bearings, and through that links to ISO Technical Committee TC4: Rolling bearings. for some years I was a  member of the BRBMA Technical Committee ( on behalf of NSK-RHP) which forms the core of MCE/7 and has represented the UK at ISO-TC4 global plenary meetings.

Business knowledge is updated through membership of a Business link network at Nottingham which draws members from public and private sector businesses from micro to global scale.

I am current Vice-Chairman of IMechE East Midlands Region and also undertake membership interviews. These activities enable me to maintain and develop links with fellow professional mechanical engineers.
