Expander System Technology

Lug wear is a common problem with all machinery. Repairs involve a costly, time-consuming process with significant downtime and must be repeated several times over a machine’s life.

With the Expander System, the repair can be carried out directly in the worn mountings without welding and line boring – a permanent solution to lug wear.

A modern alternative for lug repair

  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
