Vesconite Hilube can last up to ten times the life of bronze
Vesconite Hilube is a thermopolymer, designed for particularly difficult operating environments. Hilube is specifically recommended for moist and underwater applications. These include the pump and marine industry, where regular maintenance is not practically feasible or cost-effective. Displaying superior wear life, especially in poorly lubricated and dirty conditions, Vesconite Hilube has been shown to offer up to ten times the life of bronze bushings.
Vesconite Hilube incorporates an internal lubricant that translates into an exceptionally low friction coefficient. With excellent dimensional stability, low wear rates, and a high load-bearing capacity, Hilube excels in difficult applications.
Vesconite Hilube has been used for decades in a wide range of specialized pump bearing applications.
The material thrives in water, keeping to machined sizes without swelling and with zero delamination.
Other advantages are that it does not corrode, and helps prevent the corrosion between metal components especially in salt water; is resistant to oils and fuels; and is easy to machine, fit and remove – and prolongs shaft life.
In addition, it allows dry startup for up to 1 minute.
In an innovative first, Freudenberg Sealing Technologies has introduced a machine component that combines a plastic rotating bearing with a seal in a single, precisely matched unit.
The design offers significant weight, cost and friction advantages over separate bearings and seals and also improves the properties of the mated bearings and seals. Freudenberg has validated the advantages of this new component through extensive testing performed in a sensor housing unit including the seal-bearing component.
While mostly hidden from view, seals and bearings are nonetheless important components in automotive and industrial applications. They are key elements in operational safety and performance and their durability must be optimized to prevent system failure. At the same time, these bearings and seals must be small, lightweight and cost efficient in keeping with manufacturers’ efforts to remove cost and weight from vehicles without sacrificing performance.
Freudenberg has resolved this challenge with the introduction of its seal with integrated bearing (SWIB). The company spent two years developing this engineered solution and has successfully tested it in a sensor housing of a an electric power steering (EPS) system installed in an electric powered vehicle.
The sensor records data, like steering angle, which is critical to advanced driver assistance programs like electronic stability control (ESC). The seal inside the housing is responsible for protecting the sensor from the penetration of dust, splash water and other media over the entire service life of the vehicle. Bearings used in the assembly are also important; they must withstand significant mechanical loads – sometimes as much as 3,000 Newton (675 lbs) of radial force when a car drives over a curb with its wheels at an extreme angle.
Integrated system can reduce loads and vibration
Freudenberg Sealing Technologies’ integrated solution offers significant improvements compared with separate bearings and seals. The rigidity of the integrated plastic bearing is higher so that its deflection is reduced by nearly 50 percent when lateral forces are exerted. This reduces the induced vibrations to increase the steering comfort for the driver. The seal, on the other hand, has 35 percent less friction, which reduces resistance during steering – especially important for highly automated driving. The weight of the overall solution is reduced by as much as 80 percent through integration. Freudenberg’s patented plastic bearing plays a major role in achieving these component breakthroughs.
Automotive safety applications are subject to many requirements which individual manufacturers define according to their own specifications. Freudenberg Sealing Technologies used common specifications – a temperature resistance of -40°C to 125 °C (-40°F to 257°F) under mechanical stress, for example – to test its integrated component during the past year. Extreme cases, such as direct exposure to high water pressure, which can occur in practice during engine washing, were also tested. The seal that includes an integrated bearing proved itself in all tests. “We can now commence with customer-specific series development at any time,” says Freudenberg expert Frank Schönberg.
The design offers significant weight, cost and friction advantages
Product experts at Freudenberg Sealing Technologies are already researching additional industrial applications for the new component. In addition to automotive applications, seals with integrated plastic bearings can likely bring benefits to many industrial operations. Freudenberg is also looking to the manufacturing process for further innovation: If the seal/bearing unit is currently still being assembled, it could be produced using new materials in an integrated two-component injection molding process in the future.
A UK manufacturer of brackets for electrical equipment has changed its 3D printer bushings to Vesconite bearings.
The manufacturer had previously used roller bearings on its two Prusa 3D printers, but had found that roller bearings wore away the printer rods. They also required regular greasing, which limited production uptime and value.
Following some online searching, Triple Link Manufacturing founder Mark Bagnall discovered a reference to Vesconite 3D printer bushings and was attracted by the fact that they were low maintenance and required no greasing.
In addition, he was pleased with the fact that the product promised low rod wear and would not result in costly damage. The time spent having to strip down the 3D printers to replace the rods and bushings was costly, so combating that would provide a lot of value to the business.
Mark reports that, following some adjustments to make sure that the positioning and the spacing of the bushings was correct, the bushings have been operating well in the 3D printers.
The company has Vesconite Hilube bushings installed on one printer and Vesconite Superlube, the lower-co-efficient-of-friction polymer bushing, installed on the other.
“We produce perfectly good quality products,” states Mark, who notes that the finish is great for functional components that compete with commercial bracket suppliers.
Triple Link Manufacturing, through sister company Indigo Lime, produces Sky TV box brackets, TV wall and stand mounts, and even Playstation mountings, among other products. Mark highlights that customers are accepting the quality of 3D printed parts for functional usage since they are cheaper than injection-molded parts.
The process also allows for the production of the necessary volumes, without large overruns, and, with Mark’s expertise, he has been able to optimise the designs to reduce the print time and the material usage involved in printing, thereby further decreasing the manufacturing and raw material costs.
The company has been steadily growing its electrical equipment bracket manufacturing since sales began at the beginning of the year.
In addition, the design and manufacturing company also continues to produce prototype 3D printed parts for customers who will eventually manufacture their own injection-molded parts.
Vesconite Bushings in Future 3D Printers
As the business expands, there will be more Vesconite installed on future 3D printers due to the success of these first two runs.
Vesconite is happy to be part of the expansion of 3D printers and stands ready with its non-grease bushings.
The original article was featured on Vesconite’s website and can be found here.
Internally-lubricated, the ultra-low friction Hilube polymer has no stick-slip, doesn’t swell and provides a wear life ten times that of bronze. It machines to +/-0.001″, making it ideal for applications with tight tolerances.
Breaking World Records with Hilube
The team that was awarded the Guinness World Record in 2017 for the longest distance covered by a miniature steam train is setting its sights on improving its record.
Keyser Locomotive Works, together with the Pietermaritzburg Model Engineering Society was able to cover 330km (205 miles) in 24 hours in its record-breaking attempt, which outstripped the previous 1994 record of 269km covered in 24 hours.
It did so for a number of reasons, one of which was the self-lubricating Vesconite polymer bushings that were fitted to the connecting and coupling rods.
These internal, hard-to-reach turning components did not need to be oiled, and this helped reduce stopping times during the record attempt.
“You can’t oil these bushings on the run,” says the locomotive owner Andries Keyser.
This was not the case with many of the original bronze bushings that had to be oiled every hour when the locomotives stopped and the drivers were changed.
Six of the main crank bushings are currently made from Vesconite polymer bushings on the record-breaking locomotive named Doreen, but the intention is to replace all the bushings with Vesconite eventually so as to reduce oiling requirements in future record-breaking bids.
“The Vesconite has no heat expansion and, using a sloppy fit, didn’t heat up at all” Keyser notes.
“The engine output was not compromised in any way and still runs today on the same bushes, two years and many kilometers later,” he says.
Looking to the future with Vesconite Hilube
Another innovation that will assist Keyser to further improve the record is the fact that he is building the longest straightest track that he can in the Stellenbosch Winelands, in South Africa. This will enable the locomotive to run at higher speeds on a track gauge of only 184mm.
Known as the Winelands Light Railway, Keyser is establishing a theme park with 1/3-scale trains, matching buildings, bridges and tunnels, and a hobbies expo for locomotive enthusiasts once a year. Presently there are four steam and one electric locomotive in the engine shed, with 13 wagons able to haul up to 50 people per train. Everything is hand made and based on narrow-gauge prototypes from all over the world.
Starting on the 14th of December 2019, the park will be open on weekends, public and school holidays if the weather allows. This unique attraction aims to become the biggest family-friendly destination in the Western Cape within the next 10 years.
Keyser will make another world-record attempt sometime in the near future, and expects that between 30 and 60km will be added to the current distance record.

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.
