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, which affects both the efficiency and stability of the machine. Repairing the lugs is expensive and time consuming and is still only temporary, wear will appear again. Expander Group 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.
