Information sharing: Week 22, 2010 (HARDNESS, THREADS, BEARINGS)

Week 22. June 2010:
HARDNESS, THREADS, BEARINGS ...
I get articles regularly on various commonly found processes and components in a typical manufacturing set-up. Though most of us know them or believe we know them, these do help to enhance and sharpen knowledge on almost every aspect of a manufacturing set-up. I intend to share them here regularly so that it is of some use to anyone concerned to manufacturing, maintenance and service fraternity.

This is the 11th of the series ......

Good info Thank's.

One comment about contamination in ball bearings: Their life span is often decided during the first few minutes of use.

The classic example would be metallic particles in a brand new engine or gearbox. Those particles will immediately affect all bearings in sight, bringing their lifespan down. Have you ever tried filtering the the oil of a brand new car after the first spin around the block? The result is likely to be a shock.
