Product number: HFN6
The apparatus consists of a flywheel on a horizontal shaft carried in a pair of similar bearings, the flywheel being used to even out small variations in friction. The shaft is of mild steel, and interchangeable bearings in a range of materials are provided.
This experiment provides an opportunity to study journal bearing friction over a range of commonly used materials including a self lubricating sintered bronze. For comparison a ball bearing is supplied to demonstrate the advantages of rolling rather than sliding contact.
Torque is applied by a loaded cord wrapped round the flywheel shaft. A set of calibrated weights and load hanger is supplied for loading the flywheel.
