I guess it had to had happen. Going looking for all the old German bearings for next engine build. These are new camshaft bearings. Do not know if they are steel backed or not. The Mahle bearings from Brazil are copper backed. Silverline is the only current manufacturer that are steel backed.

I started my working life as an apprentice tool room engineer for the UK's leading bearing manufacturer - RHP Bearings
One of the tasks I was given was to evaluate the quality of the Japanese bearings compared to our own versions, this was in around 1980. They were inferior but not by much. In 1990 we were bought out by a Japanese company - NSK bearings, by then their products were far superior to ours. By 1996 I was the Quality Assurance Manager for the plant I was based at and I was able to visit Japan for a number of weeks to see how they achieved the levels of quality that were beyond us. Training and investment in capable processes. Sadly we were unable to mirror their success, economics, politics and culture got the better of us and the factory closed in 2001 Around that time I was carrying out analysis of cheap Chinese copy bearings, the quality was poor then.... but thats 20 years ago..... |
