There were few difficulties faced in the total indicated run out testing of industrial conveyor idlers, such as separate apparatuses for testing various sizes of idlers, human observation error occurrence due to the usage of analog dial gauges, time consuming due to manual operation for the rotation of idlers, difficulties in formulating the output manually. Considering all the difficulties faced in total indicated run out testing of idlers. Design and fabrication of the newly proposed machine is done. They can accommodate idlers up to three meters in single apparatus by using adjustable V-block in guide ways in order to counter the change of idlers for various sizes. To counter the problem of human observation error, digitalized dial gauges are used for easy observation of values. The idlers are rotated by means of high torque DC geared motor to take reading at 12,3,6,9’O clock respectively. The output values are being fed to the computer system by means of usb to overcome manual observation of values. We can observe that difficulties faced in manual run out testing are overcome and the testing process becomes easier.
