Expander System Pivot Pins
Expanding pivot pin system that conforms to the wear pattern and eliminates lug wear, installed more than two million times since 1985.
Description
Expander System is a pivot pin solution for machinery with mechanical pivots. It is installed directly into the existing mounting: tightening the fasteners presses slotted expansion sleeves up the tapered ends of the pin, so the sleeves expand, conform to the wear pattern and lock the system in the lug ears. It has been installed more than two million times since 1985.
