<p>The invention relates to a cylindrical elastomeric bearing with large angular deflection which includes three cylindrical elements: a central element (1) and two lateral elements (2, 3) arranged on either side of the central element (1). Each twistable cylindrical element consists of a central, deformable elastomeric part, which is relatively flexible in angle and relatively rigid radially, which is integral with an internal reinforcement and with an external reinforcement; the external reinforcement (6) of the central element (1) and the internal reinforcement (8, 11) of each lateral element (2, 3) being integral, so as to form only one single piece; the common reinforcement (13). The internal reinforcement (5) of the central element (1) is mounted on an internal sleeve (14) with which it is integrated, and the external reinforcement (9, 12) of each lateral element (2, 3) is mounted in an external sleeve (15) with which it is integrated; the internal (14) and external (15) sleeves being coaxial, in such a way that the external sleeve (15) and the internal sleeve (14) can turn with respect to one another around their common axis, without there being any practical possibility for radial deflection.
