Morgan Advanced Materials, a global specialist in the development and manufacture of seals and bearings for demanding environments, has delivered a new type of bearing for electric water pump applications in cars which reduces component count, while improving performance and engine efficiency.
As the automotive sector increases its useage of electrically controlled coolant pumps, in lieu of traditional belt-driven components, Morgan has managed to advance the basic design of the unit. Traditional electric pump design typically features an impeller shaft which is supported by two bearings. Morgan was approached by a customer with the challenge to provide a less cumbersome bearing solution without compromising overall pump performance and cooling capability.
Morgan successfully produced a bearing solution comprised of its P5600H proprietary carbon graphite material with a length-to-diameter ratio of two, which also included numerous face details and inner diameter (ID) and outer diameter (OD) slots. Morgan’s solution was more cost-effective and offered a substantially greater ease of assembly, as well as containing the vital component features which aid lubricaion and prevent slip and anti-rotation.
“Morgan’s proprietary method for producing bearings of this geometry has enabled us to deliver a range of performance advantages otherwise unattainable with conventional molding technologies,” said Michael Ritter of Morgan Advanced Materials. “Using our unrivalled expertise in the fields of materials science and application engineering, we were able to develop a process that allowed us to provide a superior solution in terms of performance and cost. Our constant focus on innovation and problem-solving is what drives us forward as a business, allowing us to solve our customers’ most pressing engineering problems.”
