Good to know the bearings numbers, but where one can find good quality ones.
I remember brands which were immencely superior to what one can buy today.
Where are Torrington, Fafnir.........? The bearings ( after extensive
testing ) I installed in a turbine ( turbine dia. 13", 18,000 RPM) of an
industrial 15 KW laser were made in Japan. They were undestructible and very
quiet lubricated with German made Klueber grease.
I hope that many will agree with me that it pays to spend 3 times more for a
bearing which will last.
The plastic into which alternator's small bearing is set is a design which
you will not find in aircraft production.
I replaced it with a wave insert in 1988 the armature turns smooth and with
no shake. Bearings are made to very tight tolerances, much closer than the
shafts or the seats.
