Hi there, all,
Back in the days when I was in gainful employment, I had a colleague who was a mechanical engineer. He observed that ball races were/are intended for continuous rotaion and that if they habitually only rotate less than a full turn the races would brinell , damaging the bearing.
This comment interested me at the time because there was an advertiser in the Amateur Radio magazines who used to sell Morse keys with their beam pivoted on ball races - he claimed this method was superior to keys with plain pivots. (A counter opinion at that time was that the best Morse key was that made for the Royal Navy which employed flexure pivots. The RAF Pattern D Morse key employed a taper pin pivot. )
