Expander Pin manufacturing

Pivots are at the center of any rotational movement. Exposed pivots often experience lug wear which occurs due to the clearance between the bore and the conventional pin. This is commonly repaired with line boring. What if there is a modern alternative to line boring that ensures no more lug wear and allows a greater capacity at any given size? Expander Pins are used on some of the world's biggest Original Equipment Manufacturers (Caterpillar, Komatsu, Volvo, John Deere etc) including installed equipment in a vast amount of industries.
