Finding the right bearing for your application can be challenging, to say the least. Given that there are literally hundreds of thousands of combinations of polymers and metals, with varying press fits and PVs (load and velocity property combined), different tribological properties and tensile strengths, making the final determination can be tricky.

Wettability Defined and Correlation to Bonding

There is usually a good correlation between bonding and wetting. Wettability can be defined as “the ability of a solid surface to reduce the surface tension of a liquid in contact with it such that it spreads over the surface and wets it.”

So, it seems intuitive that good wetting would automatically result in strong bonds. However, this is not always the case. Two different cases where this correlation can break down are:

What are ‘Fluoropolymers’ and What are their Common Attributes

June 12, 2018

The first fluoropolymer was polytetrafluoroethylene, better known by its abbreviation, PTFE

First, a definition: fluoropolymers are a family of plastic resins which are based on fluorine/carbon bonding. The family of products is varied through a manipulation of that bond by adding or subtracting fluorine through other bonds such as chlorine, ethylenes and other chemical agents.

Slide Bearings for Pipelines and Bridges

Slide plate bearings provide support and a low coefficient of friction while allowing an object to move (or slide) freely along a supporting surface. They consist of an upper and lower component and can be used in both guided and free-moving applications.
