The Future is Here!
The problem of pivot wear in machinery and equipment is well known. Even with close original tolerances, the holes in the lugs will begin to wear. This process accelerates and the holes become oval shaped, which affects both the efficiency and stability of the machine. Repairing the lugs by line boring is expensive and time consuming and is still only temporary; wear will appear again.

 

ExpanderAmericas has developed a system to permanently solve this problem.

The Expander System consists of an axle, which is tapered at both ends, expansion sleeves, pressure washers, and fastening elements. The parallel expansion of the sleeves eliminates play in the pivot lugs.

The Expander System has endless possibilities. It can be used on any equipment with mechanical pivots. It can be used on construction machinery, offshore oil drilling rigs or as safety bolts on airplanes or trains. ExpanderAmericas has designed and manufactured over 25,000 Expander System assemblies for different applications. We can also custom make any application you need; just give us the required pivot dimensions and you will soon have a drawing and a quote on your fax or via e-mail.
