Vesconite Bushings for Railway, Transportation

Vesconite has over several decades been successfully used in a number of railway applications. The material’s self-lubricating properties make it well suited to railway components that are prone to metal on metal wear and require regular greasing. Not only will a switch to Vesconite bushings avoid long periods of downtime, the noise and squeal issues commonly associated with rolling stock, is significantly reduced. With a resultant reduction in rolling resistance, considerable power savings have been noted with the use of Vesconite components.

Vesconite Hilube on Tram Drive Bushings

Vesconite - Tram Bushings for RailAustralia – An Australian tram operator continues to order approximately 100 Vesconite Hilube motor axle bushings a year, following its successful introduction to the product in 2006. The motor axle bushings, which require no lubrication and are wear resistant, have completely replaced the standard metal main drive H-class-tram bushings, which had been in use prior to the introduction of the polymer product.

CIP Composites Gate Wheel Assembly

CIP - Gate Wheel BushingThe sluice gate at Faraday Dam in Oregon operates fully submerged with approximately 40′ of head at the middle of the gate. The estimated operation pressure on each of the bushings is around 4,000psi (4ksi). The gate is used for water level control, therefore continuously makes small adjustments to its elevation.

The gate was removed in September 2014 to perform inspection of gate wheel assembly and bearings. It was determined that several of the wheels had either stopped working or fallen off due to corrosion and lack of lubrication. The remaining bearings were found to have excessive clearance due to wear. New stainless steel sleeves were fabricated by Portland Manufacturing and welded onto the gate wheel stub shafts. New composite greaseless bushings supplied by CIP were installed to replace the failed bearings.

Vesconite Ensures Smoother Operation

Vesconite HilubeUSA – An aeration windmill manufacturer installed Vesconite Hilube bushings on its windmills, leading to smoother and more efficient operation. The bushings are an essential component in aeration windmills, which aerate ponds in private and public spaces, since fan rotation is key to ensuring that the diaphragm moves up; compressed air is taken in; and the compressor builds up pressure, which is released into the air line leading to the water. Because of this, the windmills are more efficient at reducing algae and foul smells, controlling mosquitos and creating a healthier environment for fish.

Vesconite for Renewable Energy

Vesconite Hilube bushings reduce energy costs in renewable energy applications. Turbines associated with these applications need to move rapidly and easily to produce efficient power, meaning wind, wave, tidal and current-driven turbines require a low coefficient of friction.

Vesconite Rudder Bearings Reduce Wear

Brazil, Paraguay and Argentina –  The waters of the Parana River tend to be wide and deep, with significant suspended debris and sand. Due to these abrasive conditions, rudder bearings on tug boats operating on the river are susceptible to rapid wear. The result is frequent dry docking for repairs. In response, Vesconite bushings have been successfully fitted to 20 tug boats working the Parana River. The combination of exceptionally low wear, self-lubrication and easy installation makes it an ideal material for this application.

Vesconite for Marine Applications
