High speed bushings can be found in applications as diverse as agricultural equipment and rollercoasters. When it comes to high speed applications, however, polymer bushings are often underestimated.
In this blog post, we are going to discuss the top four polymer materials for high speed bushings.
Two values that are very key to the performance of a polymer bushing are the speed and pressure. In this second article of the series, we are going to review how to determine them and what effect they have on bushing performance.
Running speed is also called bearing speed or surface speed. How you determine depends on how the bushing is going to be used. If it is a rotary bushing, the equation is:
One of the major design factors in the choice of a polymer bushing is the expected operating PV. The operating PV is the product of the surface speed of the shaft and the specific bearing load, and serves as an empirical tool for comparing the performance of different bearings.
