VESCONITE RAIL

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.

Benefits for
Rail

Vesconite bushings create overall smoother train movement.

Vesconite ensures low wear in expensive rail box bearings and shafts.

Vesconite avoids the need for regular greasing.

Vesconite reduces noise and squeal associated with rolling stock.

Vesconite is resistant to oils and fuels.

Vesconite reduces maintenance on rails, wheels and axle bushes.

Common Rail
Applications

Centre cup liners

Flat liners

Brake beam guides

Couplers

Brake rigging systems

Pedestal liners

Material
Comparison

Manganese steel tends towards material fatigue and cracking.

Metal center liners have a higher friction coefficient compared to Vesconite. The result is greater turning effort and faster wear on rails and wheels.

Metal bushings and liners are difficult to remove and fit. This is not the case with Vesconite. 

Metal to metal wear causes costly downtime on rolling stock – an issue often not factored in.

Rail Case Studies
Vesconite replaces original bogie support pads

South Africa - A South African company operating a long heavy-haul railway required replacement load pads for its locomotives, as the original pads lacked sufficient load-carrying capacity and low friction performance. As a result, the locomotive wheel sets tended to run out of alignment when coming out of a curve, with associated high wear. The replacement Vesconite bogie support pads have eliminated both these problems.

Vesconite Hilube pedestal liners put to the test

Argentina - A rail company has successfully tested Vesconite Hilube pedestal liners on its locomotives over a six-year period. The Vesconite liners were found to last beyond the required maintenance schedule. Given the ease of fitting the Vesconite liners, the rail company is able to replace the liners using one engineer, as opposed to two in the past. The Vesconite replacements have also extended the life of the axle boxes and bearings.

Vesconite Hilube locomotive side-bearer guides

Australia - In this case study, a rail company requested durable side-bearing guides to replace the standard guides fitted to its passenger cars. Vesconite Hilube side-bearer guides were installed on the locomotive passenger cars, with resultant less wear than the original guides. Fitted to the side of the bogie, the Vesconite side bearers work together during the rotation of the bogie, ensuring a specified turning torque and safe operation of the rail vehicle.

Vesconite fitted to Arctic ore wagon

The Arctic - A railway line operating in the Arctic required centre liners that could function in sub-zero temperatures while carrying fully-loaded iron-ore wagons. This combination of high load and freezing conditions tended to result in rapid wear to traditional liners.  Vesconite replacements were opted for, as the material can withstand temperatures up to -40˚C. Easy machining and fitting and smooth running bogies on straight and curved tracks were the result.
