[Bell Historians] First use of roller bearings?

Sat Feb 26 11:22:04 GMT 2022

I think the query from Carl is difficult to answer as 'roller' bearings 
covers a wide range of designs. Does the newspaper article mean use of 
parallel needle rollers & not spherical self aligning rollers?

The comment by Matthew has made me aware of spherical roller bearings 
(which I think are usually 2 rows, but can be 1 row,  of barrel shape 
'rollers' ie don't ever seem to be spherical?  & can always be self 
aligning?) .

Until today  my understanding was that 'roller bearings' were a single 
or double row of needle bearings (comprising parallel 'pins') which I 
assume can never be self aligning. I think all cases these modern 
bearings are always held in a cage to keep each 'roller' separate.

I think the only rollers illustrated by Trevor Jennings are needle 
roller on page 65 which are described as roller balls but Fig 3 appears 
to indicate long / wide roller pins ie & not spherical (barrel shaped) 
balls?

I think a single row of needles on page 65 would not allow self-aligning 
within the bearing?

I think double row 'round' ball bearings only are illustrated on pages 
66 & 67 & not needle roller bearings or the spherical (barrel) roller 
bearings stated by Matthew?

Fig 3 on page 66 attempts to prevent end float problems by having balls 
at the end of the shaft.

(Searching for SKF bearings etc will provide 1000's of pages re bearings 
designs & many variations including combinations within the same housing.)
