The Role Of Small Part Innovation

By Janaki Weiden – According to the 2010 Global Innovation 1000 study conducted by global management consulting firm Strategy&, the top 1,000 R&D spenders cut their investment by 3.5 percent in 2009 to $503 billion. The dip marks the first time in the 13 years of the annual study that this group of companies reduced spending on R&D activities.

At its most basic level, a bearing provides the interface between a rounded shaft and the housing in which it rotates. Though they are often constructed from steel and aluminum, bearings are increasingly designed according to the application and can include various coatings for weather-proofing, heat protection and wear-resistance. Over time, R&D has enabled the incorporation of polytetraflouroethylene (PTFE) compounds which feature the lowest coefficient of friction of all solid materials. For example, the addition of proprietary PTFE compounds results in smoother movements and higher wear resistance. The properties are essential in bearings used in a wide range of products, including those in the appliance, automotive, bicycle and solar industries. more>
