<p>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?<br>
</p>
<p>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?) .</p>
<p>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.<br>
</p>
<p>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?</p>
<p> I think a single row of needles on page 65 would not allow
self-aligning within the bearing? <br>
</p>
<p>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? <br>
</p>
<p>Fig 3 on page 66 attempts to prevent end float problems by having
balls at the end of the shaft.<br>

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

I’ve used self aligning (spherical roller) bearings in some cases
too… you can use smaller housings that way, and the ratings are
significantly higher than using ball races.

<div>Just wondering if the distinction between roller
bearing and ball bearings is clear. Roller bearings seems
to be common parlance for anything that isn’t a plain
bearing.

Is that claim correct? If not, when
