We first entered the idler market in 1974, becoming one of the few equipment manufacturers that also supplies its own components. We are constantly engaged in research and development to craft the best idlers to fit the hundreds of conveyors that we sell each year, coming up with better designs to reject fugitive material and protect idler bearings.
