Abstract
A link assembly for a lightweight, non-metallic, conveyor or load transmission chain having significantly greater strength and other performance improvements compared to previous non-metallic chain links is disclosed. Each link assembly includes: a pair of identical sidebars each comprised of high-strength filamentary material wound in an elongated loop configuration and fixed in a matrix of hardened resin; a connecting pin having a stiff reinforced composite core and a skin-tight sleee of non-abrasive material; low friction bushing means between the sidebars and connecting pin; and retaining means for holding the assembly together. Methods of making the unique sidebar and connecting pin components are also disclosed.
