CEMA-C Belt Scale Idlers
- Douglas belt scale idlers are manufactured to prevent load shift and to help ensure accurate weight
measurements of conveyed material when used with mechanical weighing devices (belt scales). - Douglas belt scale idlers are available in CEMA C and D configurations, in 20°, 35° and 45° troughing angles. These idlers are factory lubricated and are “sealed for life” or maintenance free.
- Contact the local authorized Douglas Distributor of your choice or contact Douglas Manufacturing for further assistance.
