Vesconite and Vesconite Hilube are low friction materials for long life bearings, designed to operate with little or no greasing.

    • Up to 10 times the life of bronze bushes
    • No swell. Use where nylon unsuitable
    • Low wear. Outlasts acetal bearings
    • Under water bushes. Thrives with water as lubricant
    • Best material for dirty and poorly lubricated conditions

VESCONITE has high dimensional stability and does not swell in water, in contrast to most synthetic materials which swell in water. For example nylon absorbs up to 9% water by weight with consequent swell and softening.

VESCONITE combines a load carrying capacity greater than white metal with self lubricating properties better than nylon.

Developed and proven in thousands of industrial and marine applications, use VESCONITE when 


Not only do VESCONITE bushes generally last much longer, but the life of  mating shafts and pins is often greatly extended.

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 excellent savings over its installed life cycle.  It is stocked in a wide range of shapes and sizes. VESCONITE is easily machined to fine tolerances on standard metal working equipment.  The factory also offers a special service for the production of custom components

Vesconite parts include bushes, thrust washers, guides, wear pads, wear strips, slides, light duty gears and many other components subject to wear and friction.

The main properties which make VESCONITE an outstanding bearing material are: 

Wear resistance
VESCONITE provides outstanding wear resistance, resulting in many times longer service life when compared with bronze.  It is also less affected by poor lubrication and dirty conditions.

High load bearing strength
VESCONITE has very low creep rates and is suited to design loadings up to 30 MPa (4275 psi). 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% linearly when immersed.

The thermal expansion factor of VESCONITE is only 2.5 times  that of bronze, while nylon and HDPE are 5 to 10 times greater respectively.

VESCONITE therefore needs only slightly more clearance than the corresponding metal parts. No allowance needs to be made for moisture changes in most applications.

Low friction
VESCONITE has outstanding dynamic friction, with a friction coefficient of less than half bronze or nylon.  This allows for higher combinations of loads and speeds.

Greasing of VESCONITE bushes on assembly further decreases friction, allowing higher speeds to be used and generally improving performance.

Water is an excellent lubricant for VESCONITE, making VESCONITE ideal for many immersed applications.

VESCONITE HILUBE  offers even further reduced friction (down by 50%), making it an ideal material for unlubricated applications. 

Temperature limits
VESCONITE's melting point of 260ºC (500ºF) is one of the highest among thermoplastic materials.

VESCONITE is suitable for continuous use at 100ºC (212ºF). For higher temperature applications, submit an enquiry form.

The low thermal conductivity of VESCONITE, common to all synthetic materials, means that frictional heat is removed only slowly through the bush.

PV Limits
One should avoid extreme heat build-up by first checking the PV (load x speed) when designing a replacement for a bronze bush operating at a high PV factor.

The PV limit of VESCONITE is about twice as high as that of nylon and higher than most synthetic bearing materials.

Longer life of metal counterparts
The wear of metal pins and shafts is reduced by up to 90% when VESCONITE bushes are used. Thus the high cost of replacing expensive shafts and pins can often be saved. This valuable benefit alone justifies the change over to VESCONITE in many applications.

Chemical resistance
VESCONITE is very resistant to dilute acids, organic solvents, oils and petroleum.  It has limited resistance to strong acids and alkalis. Lengthy immersion in boiling water should be avoided.  See the Vesconite Chemical Resistance 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.

It is far easier to machine than bronze, steel, nylon, acetal, UHMWPE or polyurethane based products.

Stock sizes
The VESCONITE stock range includes hundreds of sizes of machineable rods, bushings, plates, finished bushes, discs, washers and ready to use parts. For the full range, see our Stock Range listings.

The Vesconite range includes:

From 8 to 165 mm diameter (0.32" to 6.5"). 

We have an incredibly wide range of bushing stock (tube) suitable for the smallest shafts up to 650 mm (26") diameter. Standard lengths are 1000 mm long (39.4").  Special lengths may be ordered. 

Plates and Discs
Plates are mainly available in standard sizes 1000 mm long x 200 mm wide (39.4" x 7.9") from 3 to 50 mm thick (0.12" to 1.97"), as well as specially machined strips and sections.

Discs are produced in diameters from 200 to 500 mm (7.9" to 19.7") and in thicknesses ranging from 3 to 12 mm (0.12" to 0.5"). 

Ready-to-use parts
These include over 100 sizes of ready-to-use bushes in both metric and imperial (American) sizes, while standard tooling allows production of many more sizes of plain and flanged bushes from 3 mm to 650 mm inside diameter (0.1" to 26") and washers up to 600 mm diameter (23.6").

Custom Components
Special factory services include:

  • Moulding and machining of custom components to your drawings and specifications, including extrusion and injection moulding, turning, milling, drilling, thicknessing, cutting and joining.
  • We offer a "One Stop" application development service, assisting you with the development and testing of initial prototypes to the mass production of proven parts.
  • We can economically produce small quantities of custom components using our specialised machining workshops, an extensive stock of semi-finished materials and a wide range of injection moulds and extrusion dies.
  • Our workshop can reline very large wear parts with VESCONITE strips. This saves the original expensive phosphor bronze component and makes it better than new.
  • New parts can also be produced from cheaper metals and lined with VESCONITE.
  • For new and difficult applications, if the quantities required justify the development, we can research special formulations and materials, building on our on-going technical developments.
