Gallagher Fluid Seals is proud to announce that we are now a distributor for Vesconite self-lubricating bearings and bushings.
A specialized hard-wearing thermopolymer designed for challenging operating conditions, Vesconite gives up to 10 times the life of traditional bronze or nylon bushings. Combining high-load bearing strength, internal lubrication, a low friction coefficient and low wear rates, it does not require external lubrication, even where conditions are dry and dirty. Over the past six decades, Vesconite has become internationally recognized as a versatile, high performance replacement for traditional bushing and bearing materials.
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, it retains its strength under wet conditions and displays negligible creep under high load.
Vesconite is available in a wide range of rods, bushings, plates, and machined custom parts.
Vesconite Key Features
High Wear Resistance
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
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.
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.
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).
Suitable for continuous use at 100º – 120°C (212º – 248°F) in dry conditions and 60° – 70°C (140° – 158°F) in wet conditions.
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.
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
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.
Combining an exceptionally low wear rate and shaft-friendly features, Vesconite and its corresponding parts require little maintenance – resulting in significant cost savings.
