Critical Factors: Reverse Engineering Polymer Seals, Bellows, Diaphragms, & Bearings

Posted On May 20, 2016


What is Reverse Engineering?

Reverse engineering means to recreate a part based on available data about it.  Keep in mind that the goal of reverse engineering is not so much as to create a part that looks and feels identical to the original part (although it can be), but rather provides the same (or better) performance as the original part.  The material might be different.  While it will likely fit in the same space envelope, non-critical geometry might not be the same.  However, the part achieves the same purpose and performs the same function.

PTFE and Modified PTFE Bellows:  What’s the Difference?

Posted On February 26, 2016


Polymer Bellows

Polymer bellows are found in quite a few industries, including petrochemical, medical, pharmaceutical, chemical, and the food industry.  Because of its chemical inertness, low spring life, and long flex life, PTFE is often the material of choice for polymer bellows.  However, it isn’t the only option.  In this article, we are going to compare PTFE and TFM.

What are bellows used for?

One of the primary uses of bellows is to absorb dimensional changes due to thermal effects, which is very useful when used high temperature flows such as steam.  Bellows also serve to dampen vibration in the system caused by rotating components, protect sensitive and brittle processing equipment, and to absorb shock loadings
