VESCONITE has gained international recognition as a versatile, high performance replacement for traditional materials in anti-friction and wear applications. VESCONITE'S initial cost is moderate and gives savings over it's installed life cycle.


High Load Bearing Strength –


VESCONITE has very low creep rates under design loadings of 4,351 psi (30 Mpa). Much higher load capacity than nylon and elastomers.


Dimensional Stability --


The thermal expansion factor of VESCONITE is only 2.5 times that of bronze, lower than many of the competitors. HDPE and nylon is 5 and 10 times greater, respectfully.


No Water Swell --


Only 0.5% at ambient. Negligible in sizing calculations. Most of the competition is way above this. Nylon has a 9-10% water swell. Elastomers have a 1.3 – 3% water swell. Phenolics are at generally at 1.6 - 2% water swell. Water swell is one of the primary causes leading to shaft seizure.


Low Friction --


Dynamically, about half that of bronze and nylon. This allows for greater combinations of loads and speeds. Greasing of VESCONITE further deceases friction, allowing higher speeds and improved performance. Water is also an excellent lubricant for VESCONITE bushings.


Abrasion Resistance --


VECSONITE provides outstanding abrasion resistance resulting in many times longer service life, when compared to bronze. It is also outperforms other products in poor lubrication and dirty conditions.


Longer Life of the Mating Surfaces --


The wear of metal pins and shafts is reduced by up to 90% when VESCONITE bushings are used. This fact, alone, justifies the use of VESCONITE – less maintenance.


Chemical Resistance --


Vesconite is highly resistant to diluted acids, organic solvents, oils, and petrol. It has limited resistance to strong acids and strong alkalis (see Chemical Resistance Chart).


Temperature Resistance --


Vesconite can withstand continuous temperatures up to 212°F (100°C) dry and 176°F (80°C) wet, with momentary peaks above this. Above 158°F (70°C) an expansion gap must be incorporated into the bearing design for a proper use. See the Calculation Programs for details. For a product that would be submersed in boiling water, please take a look at the Vesconite HiTemp products.
