Abstract :
This project takes up the module of Crankshaft main and sub journal bearing friction. In bearings wear due
to friction is always undesirable. Thus the reduction of friction reduces the wear, noise and improves the smooth
rotational behavior of the element. We have replaced the prolonged use of journal bearings with compact and
improved design of needle bearing. Calculation of needle bearing and journal bearing are done and comparative
results are shown. It is seen that the performance of needle bearing is higher than performance of journal bearing.
