Technology and applications

Expander System is an award-winning solution with over two million systems installed since 1985. The design is adaptable for any obstacle, lubrication and application needs. Show us your application and we will help you identify the perfect Expander design.

HOW IT WORKS

  1. The Expander System is installed directly into the existing mounting
  2. Upon tightening the fasteners, the washer presses the slotted expansion sleeve up the tapered ends of the pin
  3. The sleeves expand, conform with the wear pattern and lock the system in the lug ears
  4. Once retorqued, the system will lock from both sides
