Abstract
Small free and forced vibrations of a roller bearing have been investigated taking into account the finite contact area between the rolling body surface and the base bearing surface. It is shown that a decrease in the amplitude of free oscillations of the rolling body leads to free vibration frequency growing to infinity that represents a dynamic effect known as rattling. It is also stated that investigated bearing is a kind of filter to those external harmonic impacts whose frequencies are below a certain threshold value of the circular frequency ρ0.
