The combined tensions of the belt apply and the weight of the pulley assembly applies a force of 5.4kN and 900N respectively. The shaft has a diameter of 32mm. Bearing A at the top supports the shaft radially whereas bearing B at the bottom supports the shaft axially and radially. Two deep groove ball bearings have been selected for this application.
