A resilient bearing able to accommodate relative torsional movement between two concentric inner and outer tubular rigid members comprises between those members a resilient bearing having a layer of elastomeric material secured relative to one of the rigid members and a support member for sliding relative to the other rigid member. The support member is axially movable and preferably inclined relative to the axis of the bearing at its interface with the elastomeric material whereby any such axial movement results in compression loading of that elastomeric material.

A resilient bearing comprising an inner rigid member, an outer rigid member which extends around and is spaced from the inner rigid member to define between the rigid members an annular space and interposed between the rigid members and located in said annular space two axially arranged resilient elastomeric bearing assemblies which resiliently interconnects the inner and outer rigid members and restrict at least initial relative rotational movement of said members, each resilient elastomeric bearing assembly comprising an elastomeric element having a first surface secured relative to one of the inner and outer rigid members for rotational movement therewith by a first rigid support member, a second surface opposed to said first surface and having a second rigid support member secured thereto, said second rigid support member being adapted for sliding relative to the other of said inner and outer rigid members during increasing relative rotation of said rigid members, at least one of said support members of the elastomeric bearing assembly being arranged such that as a result of movement thereof axially relative to said one of the inner and outer rigid members the elastomeric element is loaded in compression between the rigid members, the two resilient elastomeric bearing assemblies being arranged such that movement of said at least one of said rigid support members of one resilient elastomeric bearing assembly of the pair to load the elastomeric element thereof in compression is in an axial direction opposite that in which the corresponding rigid support member of the other bearing assembly of the pair is moved to load the elastomeric element thereof in compression, and the resilient bearing comprising means to retain said support members of the two bearing assemblies in an axial position at which the elastomeric elements are loaded in compression.
