This apparatus is designed to perform experiments to understand the effects of friction in axial bearings. In this apparatus, a vertical shaft is used onto which various bearing journals are bolted at the bottom. Various bearing houses are also bolted on to the shaft. The bearing houses are of different shapes. On the top of the vertical shaft, a pulley made of anodized aluminium is fitted. A rope is attached to the pulley so students can exert torque. The torque can be measured over the load applied. Weights are placed on the pulley to adjust the axial load. The unit is operated by hand and does not require a power supply. Different materials enable the influence of the choice materials to be investigated.
