A custom machine builder needed a rubber covered aluminum roll to run at extreme high speed. New rolls from their previous supplier would shake and rumble when at run at the high speed. Webex quickly discovered that the current roll design was operating above critical speed. By working closely with the customer, we engineered and balanced a roll that not only ran at the specified speed, but was lighter and cost less than the original roll.
While touring their facility during our service call, we noticed yellow safety tape on the ends of some Webex rolls. When asked about this, we were told, "Those rolls run so well, sometimes it's hard to tell if they are turning, so we put tape stripes on the ends."
