Abstract
A laminated device such as a bearing or coupling comprising an inner and an outer housing with a laminate therebetween of alternating resilient and non-extensible layers wherein at least one of its resilient layers is made of a material characterized by having a damping coefficient different from that associated with the material of at least one other resilient layer and preselected so as to improve the uniformity of the strain distribution within the laminate and, thereby, the low temperature operating characteristics of the device. In another embodiment of the invention, at least one of the resilient layers is comprised of discrete portions or segments, each having a nominal damping coefficient preselected so as to improve the bearing's operating characteristics in low temperature applications.
