ABSTRACT:
A heavy duty elastomeric bearing typically of annular shape comprises a pair of rigid end members spaced apart and interconnected by an element of elastomeric material having embedded therein a plurality of substantially rigid reinforcing interleaves each arranged to lie in respective planes generally parallel with confronting surfaces of the rigid members. One or more of the reinforcing interleaves lying substantially mid-way between the confronting surfaces of the end members has a greater thickness than one or more of the interleaves which lies closest to at least one of the end members. The confronting surfaces, elastomeric layers and reinforcing interleaves may each be of annular part-spherical shape.
