I was advised a long time ago to get:
"New Departure Hand Book 24th edition Ball Bearing Catalog"
to learn about spindle bearings and preload, lube etc.
I'm ready to re assemble my mill. From my meager understanding, this
book is for the bearing designer and the preloades are built into the
spindle with spacers ground to exact tolerance.
The one nut to clamp the four spindle bearings was on "darn tight". I
see nothing in this catalog for a tightening procedure like you'd do
on a car or trailer axle bearing. Also, no cotter pin type arangement.
So, is "darn tight" the correct method for me?
Also, I see nothing on lube in the book. It just says "proper
lubrication" in several spots. My bearings look like they must have
been lubed with a basic car axle grease and packed by the typical
method. Is this correct?
FWIW, my spindle is just about the same as a bridegeport series one
with 40 taper tooling. You can see the details on page 22 of this .pdf
