Bearings for thermal and kinetic energy recovery systems

“In automotive and industrial applications, super precision bearings are playing a key role in both thermal and kinetic energy recovery systems (KERS), helping OEMs develop greener, more energy efficient systems”, says Chris Mitchell, Project Manager at The Barden Corporation. Although the internal combustion engine is likely to still dominate the automotive landscape for the next decade or so, the increasing mismatch between energy consumption and available resources, together with tighter legal restrictions on engine CO2 emissions, is creating an increased demand for improvements to existing automotive technologies and the development of reduced friction, more energy efficient, ‘greener’ alternatives. Barden is at the forefront of the latest developments in innovative, energy efficient, low friction, super precision ball bearings for these emerging technologies – collaborating with many of the world’s leading Tier One and Tier Two suppliers to the automotive industry. Turbochargers In order to support the growing demand for more energy efficient, low carbon emission vehicles, manufacturers of turbochargers, particularly for passenger cars and commercial vehicles, are being asked to provide more compact, higher efficiency turbocharging systems that are both durable and affordable. Barden first manufactured ball bearings for turbocharger systems in 2004. Since then, Barden has led the way in the development of new low friction double row angular contact ball bearings for turbocharger technologies. These super precision ball bearings are helping to set new performance benchmarks for the future, particularly in the high-end passenger car, light duty and heavy duty truck markets, where the individual cost of the bearing is less of an issue and where the fuel savings and reduced emissions are more immediate and noticeable.

Combined needle roller/axial ball bearings enable smooth movement of kinetic sculptures

Combined needle roller/axial deep groove ball bearings from Schaeffler are playing a key role in ensuring the smooth, quiet motion of kinetic wind-powered sculptures developed by popular UK sculptor David Watkinson. “I’ve been a full time sculptor for the last 18 years, working from my home studio in Leeds. Although most of my pieces are static, over the last four years I’ve developed three kinetic sculptures that are powered by the wind and small currents of warm air. All of these rely on combined axial and needle roller bearings, precision manufactured by Schaeffler,” says David Watkinson. Inspired by the great American artist and kinetic sculptor George Rickey (1907-2002), David’s work is sold either to private individuals as garden displays, or to organisations and charities for display to the general public. David has sold sculptures to customers all around the world, from New York to Switzerland. “Kinetic sculptures are about form and movement,” explains David. “The natural world inspires the form of my work and the unseen forces of nature [such as the wind] dictate its movement. Humans expect movements to be linear, whereas my pieces appear to defy gravity and have very unusual patterns of rotation. “My pieces are delicately balanced on precision bearings, where small air currents cause large forms such as leaves and seed pods to tip and move in reaction, carving a path through the air before returning to a balanced position. These sculptures represent a perfect combination of art and engineering, with the bearings supplied by Schaeffler being a vital component in the motion system.” “Four years ago, when I first started developing kinetic sculptures,...
