THE STRENGTH OF YOUR MACHINE IS DEFINED BY ITS PIVOTS

The Lug Wear Challenge

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.

The Solution

EXPANDER SYSTEM TECHNOLOGY

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.

A modern alternative for lug repair

1. The Expander System is installed directly into the existing mounting
2. Upon tightening the fasteners, the washer presses the slotted expansion sleeve up the tapered ends of the pin
3. The sleeves expand, conform with the wear pattern and lock the system in the lug ears
4. Once retorqued, the system will lock from both sides
