Vesconite’s Hitemp 150 hanger bearings have been installed at a palm oil processing factory in Cameroon, Central Africa. This followed a suggestion to test Vesconite Bearing’s most abrasion-resistant polymer – which also has a high-temperature rating. Abrasion resistance is important for a bearing’s success since wear can result in frequent replacement and factory downtime, while […]
Sailing yacht installs Vesconite propeller bearings
The 36-meter Miss Silver sailing yacht has returned to her New Zealand birthplace for a complete refit, including fore and aft Vesconite Hilube propeller bearings. The two bearings, 5¼-in. on the outside diameter, 4¼-in. on the inside and 17-in. long, replaced phenol-ic-backed rubber bearings. The Vesconite Hilube bearings offer the advantage of close clearances, thus […]
Texas pump manufacturer orders Vesconite bushings for new range
Some 2,000 pump bushings have been ordered for a new vertical turbine range that is being developed by a Texas pump manufacturer. The pump manufacturer has been a client of Vesconite Bearings since June 2012, ordering wear-resistant Vesconite Hilube bushings for applications that call for small clearances in sometimes abrasive conditions. With the design of […]
Vesconite deflector protects 30% of pump value.
A starch and glucose producer in South Africa fitted Vesconite wear-resistant deflectors to its centrifugal pumps in 2019, and substantial maintenance, component, and capital-cost savings resulted. Deflectors are cylindrical rings placed at either end of the bearing assembly around the shaft. In this application, they fit at the end of oil lip seals to prevent […]

The company has already installed the first phase of its solar project, comprising 14 strings of 18 x 350 W Canadian solar panels and a 66 kW Schneider Electric […]
Bushings still operating at Nile hydropower project
Vesconite Hilube bushings, which were installed on the control arm linkages on the radial deep sluice gates on a hydropower dam on the Nile River, are still operating some seven years after a complete overhaul of the systems controlling water flow in 2013. A company representative reports that the sourcing and specifying of components, including […]
Farm equipment designer specifies Vesconite
A custom farm implement designer will recommend Vesconite for all the bushings on a ripper/cultivator that he is currently designing, in line with a belief in Vesconite’s no-swell self-lubricating wear-resistant characteristics that have led to him using the bearing material on all of his agricultural equipment. Designer and innovator Kobus van Zyl, of Verbo Engineering, […]
Better than the OEM forklift spares
Bearing and wear part manufacturer Vesconite Bearings has increased its efforts to develop better -than-the-original-equipment-manufacturer (OEM) forklift parts. The company has long known that its gantry support bearings, tilt cylinder bushings, side shift pads, mast pivot bushings, steer axle articulation bushings, king pin bushings, and lever and pedal bushings offered low-friction, wear-resistant, and high load […]
More efficient pumps easily achieved with new wear rings
Independent tests by a major pump manufacturer prove corrosion-free Vesconite Hilube wear rings safely allow reduced running clearances and improve pump efficiency. Bronze casing wear rings with a clearance of 0.3 mm were tested against no-swell Vesconite Hilube at 0.1 mm Pump efficiency increased from 80.50 to 82.55%. Pumping head increased from 30.204 to 30.818 […]

Vesconite wins over rubber propeller bearing
While many have historically praised rubber and nitrile rubber marine bearings, Vesconite Bearings, the maker of the no-swell Vesconite Hilube polymer, has seen ship repairers increasingly turn to its product. Such was the case in June, when one New Zealand repairer, who has traditionally only used rubber bearings, requested Vesconite Hilube for two sailing yachts. […]
Trunnion bearings in Hydro Power Plant’s tainter gate application
Vesconite Hilube trunnion bearings have been used on the Kruisvallei Hydro Power Plant’s tainter gates, which are to be installed this year on the Ash River, halfway between Bethlehem and Clarens, in South Africa. From the side, tainter gates look like a slice of pizza with the curved part facing upstream of the canal and […]
Vesconite Hitemp 150 used in condensate pumps
Condensate pumps can get very hot. They are used in industrial steam systems to collect and return steam to a boiler for reuse. This is why when a large energy company in Africa required lineshaft and bowl bearings for condensate pumps at its 4,000 MW power station it turned to Hitemp 150, an engineered polymer […]
