Stainless Steel

Many customers, who have come to Coast Controls with their most demanding web guiding applications, have also used our custom idler rollers. After all, we’ve been making quality idlers as part of our web guide systems since 1992. 

Today, we engineer stainless steel idlers for corrosive and high moisture environments. Each roller is designed to meet the exact specifications of its intended use. These idlers provide exceptional performance over a wide range of applications while possessing a higher wear resistance than mild steel. Typical applications include food and medical environments. Stainless Steel bearings are also available for dead shafts.

Dead Shaft Stainless Steel Idler Rolls

  • Grade 304 Tubing machined for minimal stock removal
  • 32 Ra finish on roller face
  • Dynamically balanced to ISO grade G6,3
  • Straightness over roller face width within the greater of 0.002” or 0.0005”/ft of face length
  • Low-Friction bearings, steel or stainless steel

Live Shaft Stainless Steel Idler Rolls

  • Grade 304 Tubing machined for minimal stock removal
  • 32 Ra finish on roller face
  • Dynamically balanced to ISO grade G6,3
  • Straightness over roller face width within the greater of 0.002” or 0.0005”/ft of face length
  • Journal Material grade 304 stainless steel
  • Journal run out to roll O.D. within 0.003″

Live Shaft vs. Dead Shaft Stainless Steel Idlers:

If you have decided to go with a stainless steel idler, another decision you will need to make is if you want live shaft or dead shaft.  Each has their key advantages and the decision depends solely on your unique manufacturing requirements.

  • Dead Shaft
    Dead shaft stainless steel idlers are less expensive than live shaft idlers, which has made them more popular over the years.  Also, since the roll body is the only rotating object on a dead shaft idler, the rolling inertia is much less than a live shaft.  Dead shaft idlers also benefit by having low friction bearings, which help increase the bearing life span.

 

  • Live Shaft
    The most popular reason people go with live shaft idlers is because they can work in harsher environments like those that involve damaging chemicals or vapors, high levels of dust, or excessive moisture.  Also, since the bearing size is not limited to the size of the idler roll body, live shaft idlers can withstand higher workloads.  Another key advantage of live shaft rollers is that they can allow for longer rolls since self-aligning bearings can be used. Live shaft idlers can also work in elevated temperatures when positioning the bearings outside the harsh environment which prolongs the bearing life.
