Re: SB 9C HEADSTOCK SPINDLE BEARINGS


john kling
 

Some one thread remarks that the front bearing are normally brass. Babitt, bronze or other materal  bearings were the norm for early lathes but the light/cheaper  SB lathes, 405, 415, workshops most frequently used the headstock material for the bearing surfaces. Often the spindle was "super polished" to facilitate the inexpensive approach. This approach was used by some other lathe makers. as well. It does not seem to be a major flaw. The spindles seem to frequently fail before the beds develop excessive wear. You will notice that some SB users are fanatics on proper oiling. That said other makers with roller and bronze bearing also put great emphasis on proper lubrication.

I do not hear any noise from the roller thrust bearings.

I have had a further look at pictures and
information on the net, and my lathe could be a type 15
which appears to be the for-runner to the 9C what makes me
think that, is the type 15 has the brass name plate the same
as what is fitted to my lathe. The 9C's don't seem
to have the brass plate, I'm only guessing this from
what I have seen from information on the net.

The bearings are the main
spindle bearings that support the spindle, where from what I
have seen they are normally brass.
