The paper is proved to one of the important conveyer transport system task – to roller’s term of service (TS) determination. The task solving permit to evaluate the different designs belt conveyers reliable. The article represent the tasks of belt conveyers roller’s average TS determination were set and solved for the different types of roller supports. Dynamic efforts arised with the loading motion and caused with belt bend are principal factor for the calculation of TS rollers. The graph of dependence roller’s average TS from belt velocity for different roller’s types were obtained. Obtain analyses results permit to set: average roller TS decrease under velocity increases for all types of roller’s, TS for dumping overhead roller supports and damping roller supports is substantially greater, then for hard and overhead roller supports. In addition, at some values of the belt velocity TS service can sharply decrease for all types of roller supports. It takes place in resonances related to vibrations of belt at motion of large pieces of load. Achieved results may be applied in mining, metallurgical and building industry.
