nicad an interesting project! are you by chance the the same
nicad that posts on AO?
the bearings that you list are normally used placed against
each other, or separated by an inner AND outer race spacer
of the exact same height .
the manufacturer applies the correct preload during manufacturer
so the end user just has to correctly lock the outer and inner races to housing and shaft.
most machine builders lubricate small bearings of this size with
grease.(yes including at high speeds)
Kluber Isoflex NBU-15 is the prefered brand and grade of grease
for most greased spindles.
A quantity of 15-25% of the internal volume of the braring is
used (the internal volume is listed in the bearing catalogues.) |
