Vesconite bushings on a vertical borer stabiliser rod
A earth-boring company was looking for a durable material to create stabilisers for its borer machines. The machine bores between levels in mines and is capable of boring chutes up to 120m. The drill steel is subject to high levels of grit and rock. The Vesconite stabilisers help align the drill steel, thereby avoiding whip in the drill. Despite the dirty conditions, the new stabilisers required no lubrication between recommended overhaul schedules, and general maintenance and downtime were substantially reduced.
