Vesconite in Mining

Vesconite’s origins lie in the gold mining industry, a notoriously harsh working environment. The product was developed as a maintenance-free alternative to bronze bushings traditionally used in mining equipment. Unlike bronze, Vesconite eliminates three key issues: The need for regular lubrication; the effects of dirt and grit on costly components; the damage caused by water to traditional bushing materials. Vesconite offers up to 10 times the lifespan of traditional bushes in these harsh conditions, and saves hours of downtime caused by machines requiring frequent lubrication.

Common Mining Applications


  • Vesconite has been shown to offer up to 10 times the life of bronze in these harsh conditions.
  • Vesconite is hard wearing and eliminates time-consuming greasing of bushing parts.
  • Vesconite prevents damage to costly machine shafts.
  • Vesconite is unaffected by dirty, gritty and damp conditions.
  • Vesconite does not swell or distort when exposed to water.
  • Vesconite low friction co-efficient and high abrasion resistance is well suited to many mining applications.


Between the pump impeller and casing wear rings, tight clearances are required. Swelling and corrosion can be an issue with traditional materials.

This is not the case with Vesconite due to its virtually zero water absorption rate and dimensional stability, and no bimetallic corrosion.

Unlike bronze or rubber bushings, fresh and saltwater serves as an effective  lubricant for Vesconite Hilube. This makes it an ideal material for pump bowl bushings and stuffing box bushings.
