Idler Rolls

Idler rolls are the backbone of most web fed applications yet they don’t get the credit for a quality product. A quality idler roll usually goes unnoticed in the overall operation of most lines.

Conversely a poor quality idler gets noticed a lot:
  • • If it’s out of balance, it can cause undo vibrations throughout the machine line.
  • • If its straightness isn’t held, it can cause web drift.
  • • Rough surface finishes or surface defects might mark the web.
  • • Excess run-out shows up as angular misalignment and can cause a myriad of problems.

At C.R.E.W., we’re intimately familiar with idler roll standards of the industry and we not only meet them, but beat them.


As a general rule, you can expect a C.R.E.W. idler to meet the following criteria:
  • 32 Ra surface finish
  • Dynamically balanced to well within Quality Grade G 6.3 @ 1000 to –2000 FPM (or your line speed)
  • Straightness across the roll face within .0005 per foot of face length
  • Run-out within .002–.005 (depending upon the diameter-to-face ratio)
  • Materials & Types:
