Constructive arrangement added to a support for assembling agricultural tilting bearings with new constructive form applied to the assembly support, which comprises the arrangement of multiple and contiguous openings practiced on its upper portion, so as to allow the use, in different diameters and different inter centers, of fastening elements. Alternatively, the multiple openings can be of analogous conformation and not contiguous, so as to allow the desirable interchangeability among different brands and models of agricultural equipment. The new constructive form of the support foresees the arrangement of hollow ears at opposite side ends, and also the arrangement of openings practiced on its lower ends, preferably with recesses tied in one of the ends of the fastening methods for their retention at the tilting bearing.
