The Case for Matching Shaft with Self-Lubricating Bushings

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. During start-up, the shaft rubs against the …

Metal Bushings and High Load Applications

One of the chief difficulties in traditional metal bushings 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 …

Why Are PTFE Bushings Better than grease lubricants?

A bushing’s load and dynamic speed condition create heat through high surface interaction that generates friction. Heat, if not properly adjusted, will cause a bearing to fail. Lubrication is the key element in controlling bushing friction and providing an adequate design life. In essence, it allows the bearing system to survive. Where PTFE Bushings Excel …
