They can be used as a complete multiple roller Impact Idler Set, or commonly used in a 5 roll set in the center locations to absorb high impact loads, with two steel rollers in the wing location under the skirting area. The Impact Roller has as an added feature where the heavy-duty polyurethane “Bull Nose” discs are keyed to the shell tube to prevent “walking off”. Where extra high Dynamic Rating Bearings are needed, with a greater tolerance to shaft deflections, spherical roller bearings with common physical dimensions to the Single Row Deep Groove type, are used as shown in the illustrations. The bearings are factory greased for life with Shell Alvania HDX2 or approved equivalent by the bearing manufacturer. This offers maximum protection to impact forces and resistance to water wash out.
