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.EXPANDER SYSTEM TECHNOLOGY

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. 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.
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?
