cushion_arc_impact_idlerFinally, an impact idler has been designed that can maintain superior operating performance in any field condition while protecting your conveyor belt. The incomparable durability of Cushion Arc® Impact Idlers is obvious in each of its high quality, heavy duty components.


The Cushion Arc® Impact Idler from Richwood is designed to provide true arc impact protection in an exceptionally heavy duty idler. The unitized frame is built to withstand extreme operating conditions.

Cushion Arc’s multiple rollers provide smooth, full belt width radius support trough transitions that protect the belt from damage, unlike the sharp junction points found in conventional idlers.

Quality Components

The Roller Segment – Each Cushion Arc® Idler has 5-9 individual rollers. These are impact resistant 6” diameter R2000 rubber molded over a 2 ¾” diameter steel shell. Each roller uses permanently sealed 1 ¼” ball bearings on the solid steel shaft to complete the assembly.

The Roller Frame – Offers independent support for each impact roller on the main idler frame for simple installation. As shown here, the roller T-frame quickly slides on and off from the side of the conveyor for change out of individual rollers.

The Unitized Steel Support Frame – provides unsurpassed durability in any application. The entire unit can be installed with the belt in place. Available for all belt widths and any support profile.
