Vesconite and Vesconite Hilube are ideal for the submerged and corrosive conditions of the marine industry. Suited to both dry and underwater applications, Vesconite’s internal lubricants allow for prolonged life where the setting is characterized by irregular greasing schedules, or no greasing at all. Unlike most bearing materials, our polymers have a long wear life and a high load-bearing capacity with no distortion or delamination, despite the wet and abrasive working environment. Vesconite is also easily removed and refitted, saving in costly downtime. Over the past 50 years, hundreds of industrial and leisure marine applications – from yachts to supertankers – have been equipped with Vesconite and Vesconite Hilube, testifying to the polymers' success in this industry. Common Marine Applications: Stern tube bearings, Rudder bearings, Marine winch bearings, On-board machinery bearings, Container ship hatch covers. Johannesburg, South Africa and Denver, Colorado
