Expandable Pin Assembly
Product Description
The Expander system (expandable pin assembly) is a pivot assembly for securing a pair of mounting lugs and stabilizing a machine member. The machine member is often a bearing or a bushing. The system consists of an axle with tapered ends and a locking mechanism on each side. The locking mechanism comprises a sleeve and a bolt or a nut and sometimes a tension washer. When a force is applied to the sleeve via the fastener or the washer, the tapered end of the axle will work as a guide for the sleeve, and it will expand radially. A high tension is established in the contact material of the axle, sleeve and lug ear. The tension causes friction between the tapered axle end and the sleeve, and between the sleeve and lug ear. The friction between these surfaces creates a very strong locking of the expander system.
