    <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>
