The failure cause is usually to be found in the installation itself and may be the result of poorly adjusted pulleys and rollers, incorrect application of belt tracking measures or faulty design.pulley equal to one belt width for 20 troughed idlers, 112 times belt width for 35 troughed idlers, and twice the belt width for 45 troughed idlers. It is good practice to use a 20 troughing idler as a transition idler for the first and last idler when using 35 troughing idlers, and both a 20 and a 35
