Q&A: Which material do you recommend for small construction equipment? Our cast nylon bearings are not lasting as long as we’d like.

April 3, 2012

This question was posed to us from a manufacturer of small excavators, the kind you often see in the consumer rental market.  Cast nylon is a good material for farming and construction, but with some drawbacks when it comes to moisture absorption and UV stability.  Depending on where you use them, nylon is good for cable sheaves, but for pivot points, we recommend these materials for top performance.

Q & A: Can I use gamma radiation to sterilize a Teflon part?

December 7, 2009

The first part of the answer is we need to know what kind of Teflon. DuPont's family of Teflon products includes a number of different materials. PTFE is the best know of this family and the answer to your question for this material would be NO! PTFE does not hold up well at all in gamma radiation. As an example, 4Mrads of exposure reduces the tensile strength of the PTFE to 2% of it's original value.
