The strength of your machine is defined by its pivots. All machinery is subject to lug wear over time. Lug wear occurs due to the clearance between the bore and the pin.

The performance of pivot points directly affect a machine ability to perform its task safely and with high precision.

With Expander System, the repair can be carried out directly in the worn mountings without welding and line boring. 
The Expander System is installed directly into the existing mounting, eliminating the play and distributing the load.
