    VESCONITE PRODUCTS – MATERIAL OPTIONS FOR RAIL

    VESCONITE SUPERLUBE

    Vesconite Superlube is a highly advanced thermopolymer in the Vesconite range. This low-friction, low-wear material has unusual properties providing damping for bogie stability. The static and dynamic coefficients of friction are similar, reducing jerking motion and promoting smooth sliding. Superlube was developed to solve wheel wear problems on heavy-haul locomotives.

    VESCONITE HILUBE

    Vesconite Hilube is an advanced thermopolymer in the Vesconite range. Combining low friction and low wear properties, Vesconite Hilube performs exceptionally well under high loads in difficult operating environments. Vesconite Hilube reduces wear to mating surfaces.

    VESCONITE STANDARD

    A specialised hard-wearing thermopolymer designed for challenging operating conditions, Vesconite gives up to 10 times the life of traditional bronze or nylon bushings. Combining internal lubrication, a low friction coefficient and low wear rates, Vesconite does not require external lubrication, even where conditions are dry and dirty.

    HILUBE 20

    A material with high impact-strength for demanding rail applications where peak loads are less predictable. Hilube 20 is a medium-to-low friction material designed to be resilient while operating with low wear to expensive components like axle-boxes and top-centre-plates.

    HILUBE 10

    A material with high impact-strength for demanding rail applications where peak loads are less predictable. Hilube 10 is a cost effective bearing material designed to be resilient while also protecting expensive steel wear surfaces.

    Vesconite materials are self-lubricating and homogenous to provide consistent friction properties over an extended service-life. This means no layers, no delamination and no change in friction over time. The longest known service-life of a Vesconite component is 19 years for a propellor-shaft bearing.

      Vesconite Key Features

      IMPROVES
      BOGIE STEERING
      Low-stick-slip liners allow bogies to make fine steering adjustments without a buildup of force typically required to overcome static friction and this dampens oscillations.
      REDUCES WHEEL &
      RAIL WEAR
      Low-friction bogie liners reduce rotational resistance and wheel-rail interface forces. Lower steering forces result in less wear wheel and track wear.
      SAVES ON
      MAINTENANCE COSTS
      Vesconite Rail liners are self-lubricating and grease-free. Vesconite also reduces wear to expensive steel components.
      DIMENSIONAL
      STABILITY
      Vesconite has good dimensional stability in wet conditions and with changes in temperature.
      LOW
      FRICTION
      Vesconite materials are available in a spectrum of low-friction levels for different applications with varying performance and durability requirements.
      TEMPERATURE
      LIMITS
      Vesconite is suitable for continuous use at 100º to 120°C (212º to 248°F) in dry conditions and 60° to 70°C (140° to 158°F) in wet conditions.
      EXTENDED
      BEARING LIFE
      Vesconite reduces wear to expensive steel wearing surfaces such as axle-boxes, top centre plates, brake beams and brake-linkage pins.
      CHEMICAL
      RESISTANCE
      Vesconite is resistant to dilute and moderate acids, organic solvents, oils and petroleum. It has limited resistance to strong acids and alkalis. Chart for details.
      EASY TO
      MACHINE
      Vesconite machines easily on wood working and metal working equipment, such as lathes, milling machines, bandsaws, drilling machines, planers, spindle moulders and routers.
