A bushing design that experiences frequent start-ups and shut-downs can lead to premature wearing – or even failure. This also happens when a bushing runs too dry, for example when there is a sudden loss of contact lubrication, an aggressive contamination influence or simply an under-designed mating shaft.
Understanding Bushings
Bushings are the bearing with multiple uses and names – bushing, bushes and often times just the term bearing is used.
Metal-Polymer Bushings and High Load Applications
One of the chief difficulties in traditional bushing design is lowing friction and preventing premature wear, despite lubrication. This lifecycle concern comes as no surprise given that efficient machines run around the clock and typically produce varying degrees of heat profiles within the operating systems. A secondary lubrication source, such as a costly grease or oil, should be avoided but may need to be considered to help manage the destructive heat influences.
