Abstract: The present disclosure relates to the field of mechanical engineering. The bearing of the present disclosure comprises few components and can be assembled easily on site. The bearing includes a housing and a plurality of sectional elements. The housing is disposed on a base and has a hollow profile. The plurality of sectional elements is disposed within the housing and is configured to hold the component therewithin. The plurality of sectional elements facilitates rotation of the component. Each of the plurality of sectional elements is defined by an operative outer surface and an operative inner surface. The operative outer surface has a shape complementary to an operative inner surface of the housing. The operative inner surface of each of the plurality of sectional elements has a shape complementary to the component to be held within the bearing.
