Webthe bearing characteristic number also decreases. Hence, the operating point will shift towards C, resulting in lowering of the friction and the temperature. As a consequence, the viscosity will again increase and will pull the bearing characteristic number towards the initial operating point. Thus a self Webb) Select a single row, deep grove ball bearing for a radial load of 4200 N and axial load of 5000N. Operating at 1550 rpm for an average life of 5 years at 8 hours per day.
