2.1 Rolling Bearing Construction Rolling bearings basically consist of four parts (outer ring, inner ring, rolling elements, cage). The shapes of parts of typical bearings are shown inFig. 2.1. ¡Rolling bearing rings (inner and outer rings) or bearing washer 1) The surface on which the rolling elements roll is referred to as the "raceway surface."

1. Calculate the 'Geometric Mean of the extreme diameters of each step (D)' using Table 7.8 where D = (product of the diameter steps) in mm. The given diameter 40 mm lies in the diameter step 30 mm and 50 mm. Hence, D = (30x50) = 38.73 mm.

Here is a list of machine elements. 1. Power Transmission Shafts: Shaft is a machine element, which is used to transmit power from one member to another member. When a tangential force is acting on the shaft, a turning moment is set up. This makes the shaft to rotate for transmit­ting power from one shaft to another. Pulleys, gears etc. are mounted …
