Vesconite

Over the past six decades, Vesconite has become internationally recognised as a versatile, high performance replacement for traditional bushing and bearing materials. Offering a unique combination of high-load bearing strength, low friction and low wear, Vesconite does not require manual lubrication, even in harsh and dirty working environments.

Tried and tested in literally thousands of applications across a wide range of industries  – from general industrial, to marine and agriculture. Vesconite has an impressive dimensional stability, and unlike many synthetic alternatives, Vesconite retains its strength under wet conditions. It displays negligible creep under high load.

Vesconite is available in a wide range of rods, bushings, plates, and machined custom parts.

VESCONITE KEY FEATURES

Internal lubrication

Vesconite has built-in lubricants that translate into low friction and long life, even where no lubrication is applied.

High wear resistance

Vesconite provides outstanding wear resistance, resulting in extended service life compared to bronze bushings. Unlike many traditional materials, Vesconite is less affected by poor lubrication and dirty conditions.

High load bearing strength

Vesconite has very low creep rates and can therefore operate under tight tolerances. It has a much higher load capacity than nylon, and its compressive strength and clearances are not affected by water absorption.

Dimensional stability

Vesconite does not swell when exposed to water or humid conditions, while nylon can swell up to 3% when immersed. In most applications, little allowance needs to be made for moisture changes.

Low friction

Vesconite has outstanding dynamic friction, with a friction coefficient (0.08) of less than half that of bronze or nylon. This allows for a higher PV ratio (load x speed).

Temperature limits

Vesconite is suitable for continuous use at 100º – 120°C (212º – 248°F) in dry conditions and 60° – 70°C (140° – 158°F) in wet conditions.

Shaft friendly

With Vesconite, the wear rate of corresponding metal pins and shafts can be reduced by as much as 90%. The resultant cost-saving benefits can alone justify a switch to Vesconite in many applications.

Chemical resistance

Vesconite is resistant to dilute and moderate acids, organic solvents, oils and petroleum. It has limited resistance to strong acids and alkalis.

Easy to machine – easy to fit

Vesconite machines easily on standard wood- and metal-working equipment, such as lathes, milling machines, bandsaws, drilling machines, planers, spindle molders and routers. As many of our customers around the world will testify, Vesconite is a both a pleasure to machine and fit.

Cost saving

Combining an exceptionally low wear rate and shaft-friendly features, Vesconite and its corresponding parts require little maintenance – resulting in significant cost savings.
