Vesconite, a market leader in grease-free polymer bushings and wear materials, has developed a food-grade, high-temperature, abrasion-resistant bearing poloymer.
The polymer is known as Hitemp 150 FG (food grade), and its name signifies that it can be used in applications that run at temperatures up to 150ºC and in which food contact is incidental or likely.
The previous version of Hitemp 150 did not explicitly use food grade ingredients, but, as a result from calls from the food industry to produce a similar hard-wearing product for use in food applications, alternative ingredients were sought for food safety.
“We have produced this Hitemp 150 FG product in which a food-approved ingredients have been used,” comments technical sales representative Eddie Swanepoel.
“It is cream with a streaky marble look as opposed to the previous rust-coloured Hitemp 150 polymer,” he notes.
The next step is to have the polymer approved as compliant with Standard 51 of the US’s National Sanitation Foundation (NSF), the standard that deals with polymer materials and components used in food equipment, including products that come into contact with food and beverages.
Vesconite Bearings is confident that the newest version of the Hitemp 150 FG polymer will be judged to be food grade since all the raw materials ingredients are certified as food grade.
Stay tuned for this excellent addition to the product catalog from Vesconite.
The Dakar Rally (or simply “The Dakar”) is an annual rally raid organized by the Amaury Sport Organisation. Since its inception in 1977, most races took place from Paris, France, to Dakar, Senegal. But due to security threats in Mauritania, which led to the cancellation of the 2008 rally, races since 2009 have been held in South America. The race is open to both amateur and professional entries, of which amateurs typically comprise of eighty percent of all participants.
The race is an off-road endurance event. The terrain that the competitors traverse is much tougher than that used in conventional rallying, and the vehicles used are true off-road vehicles rather than modified on-road vehicles. Most of the competitive special sections are off-road, crossing dunes, mud, camel grass, rocks, and erg among others. The distances of each stage covered vary from short distances up to 800–900 kilometres (500–560 mi) per day.
Vesconite Hilube Bushings in Suspensions of Colcar’s Racing Team Vehicles
Colcar Racing Team is a partner of Vesconite, and used the no-grease Hilube busings in the suspensions of their racing vehicles during the 2019 Dakar Rally.
The use of Vesconite Hilube in the Argentinian team’s vehicles builds on a growing record of Vesconite Hilube use in their yearly Dakar entries.
In 2018, Vesconite Hilube bushings were fitted to two trucks, one of which finished in position 23. In 2017, meanwhile, the Argentinian team finished in 33rd position, and continued to use their Vesconite Hilube bushings for two other local competitions that covered a total distance equivalent to three Dakar Rallies.
For the 2019 Dakar Rally, Colcar Racing Team participated in the truck category (vehicles weighing more than 3,500 kg – or 7,700 lbs), as well as the utility vehicle (UTV) category, also known as four-wheel side-by-side vehicle or recreational off-highway vehicle category.
The Colcar UTV won its category and finished 18 overall.
Vesconite’s polymer bushings put to the test in the 9,000 km race
“The polymer bushings have proven themselves over the grueling annual 9,000 km multi-country South American Dakar endurance race that covers various terrains, including sand dunes, mountains and salt flats,” comments Leandro Panzini of VesArg, the Argentinian distributor of the Vesconite Hilube.
“Suspension bushings are important in vehicle safety, ride comfort and handling and also align suspension and steering components … and they are paramount in the Dakar, in which vehicles travel at between 100 and 200 kilometers per hour (62-124mph) in all kinds of terrain over 15 days,” he says.
In the Dakar vehicles, the bushings were exposed to an oscillating movement with many cycles per minute taking place, and performed much better than the nylon-molybdenum bushings that they replaced, reports Panzini, who is proud to have Vesconite Hilube associated with this historic race and performing so well each year in race vehicles.

I can’t understand why more farmers don’t use Vesconite. -Old Farmer
This comment was made by an old farmer who had driven 185 miles (300km) to buy Vesconite bushings from our Johannesburg sales office. We can’t help but agree with this sentiment – that any farmer who hasn’t tried Vesconite for bushes, and other sliding wearing parts is unwittingly creating unnecessary work and expense for themself.

Hydropower has been used for thousands of years and represents the largest, most efficient and proven renewable energy source on the planet. The rehabilitation and repowering of existing generation stations, as well as developing generation at non powered dams, and introducing pump storage strategies provide a multitude of opportunities for continued growth within the industry. Water management in much of the world is faced with changing regulations to support the balancing act between power generation, ecological sustainability, and agriculture irrigation. New technologies, equipment, and modern controls systems to optimize production are aiding the industry in this balance while continuing to increase power generation.
Suppliers, like Columbia Industrial Products, must be equipped to provide quality assurance, formal documentation, and products that will perform for decades in mixed use environments. CIP has built a solid reputation while working with the US Army Corps of Engineers, Utilities, and Contractors fulfilling these requirements while providing a high quality bearing product.
CIP Composites is the leading manufacturer of environmentally friendly, self-lubricating bearings and wear pads designed to replace greased bronze components inside a variety of turbine designs, gates and valves, and auxiliary equipment. CIP composite products provide the perfect balance of performance, availability, and cost to satisfy the most rigorous demands of your hydro generation project, no matter the schedule or scale.
USA – An aeration windmill manufacturer installed Vesconite Hilube bushings on its windmills, leading to smoother and more efficient operation. The bushings are an essential component in aeration windmills, which aerate ponds in private and public spaces, since fan rotation is key to ensuring that the diaphragm moves up; compressed air is taken in; and the compressor builds up pressure, which is released into the air line leading to the water. Because of this, the windmills are more efficient at reducing algae and foul smells, controlling mosquitos and creating a healthier environment for fish.
Vesconite for Renewable Energy
Vesconite Hilube bushings reduce energy costs in renewable energy applications. Turbines associated with these applications need to move rapidly and easily to produce efficient power, meaning wind, wave, tidal and current-driven turbines require a low coefficient of friction. Reduced energy losses as a result of the lower friction present in Vesconite Hilube bushings, allow turbines to rotate easily, producing electricity faster and at a reduced cost.
The environmentally sensitive hydro-power industry requires components that last longer in the absence of contaminating lubricants. These two factors alone make Vesconite Hilube the ideal bushing and bearing material in these demanding conditions. Water serves as a natural lubricant for Vesconite Hilube, which in turn, ensures a clean and grease-free operating environment. Unlike many traditional materials, Vesconite Hilube does not swell in water, nor does it distort or creep under load within wet hydro-power settings. Therefore not only does Vesconite last longer, so does it’s metal counterparts.
Hoover Dam pressure relief valves fitted with Vesconite Hilube
Vesconite Hilube has been the preferred choice for the pressure relief valves (PRVs) at the Hoover Dam. Originally designed in the 1930s, the PRV’s divert water around the turbines when flow to the turbines needs to be stopped. Vesconite Hilube was selected to replace the existing cast iron parts, which had oxidised and seized, preventing the valve from functioning. Vesconite Hilube has proved to the ideal material for this application, due to its self-lubricating, hard-wearing, corrosion-free and low slip stick features.
Gallagher Fluid Seals is a distributor of CIP Composites full product line. CIP Composites are laminated polymer materials made by impregnating textile with thermoset resins. The physical properties of CIP materials make them superior bearing materials. CIP Composites offer design engineers an attractive, cost effective alternative to the traditional material used for bushings, bearings, wear pads, and thrust washers. The following describes the physical characteristics and application factors to replacing bronze bearings with CIP Composites.
Coefficient of Friction
CIP Composites have lower coefficients of friction than bronze in both static and dynamic situations. It is common to achieve 50% lower coefficients of friction when transitioning to composites. Bronze bearings pose a risk for metal to metal contact if grease is non-existent or not sufficient to support the shaft, and may develop high break-away torque requirements after prolonged periods of rest. CIP Composites are self-lubricated, minimizing the concerns with lubrication systems, specifically in high load, slow speed, or oscillating applications. CIP Composites eliminate noisy stick-slip problems, extend operating life and reduces wear, making for better operating efficiency.
There can be concerns with moisture absorption for non-metallic materials. Moisture absorption can create swell and expansion of the bearing material and potentially premature failure. Some common plastics in use today have water absorption rates as high as 5-7%, which can lead to bore closure of the bearing and seizing on the shaft. CIP Composites have a negligible absorption of less than 0.1%, and effectively eliminate this concern when moving away from a metallic solution.
