We had an interesting call on our Ask the Experts line this week concerning underwater bearings and the benefits of wood vs. plastic in a hydro plant application. One surprising fact we reviewed is that like plastic, wood bearings are self-lubricating materials that never require greasing. Yet plastic bearings (such as Ultracomp 300) offer the advantages of dimensional stability in liquids, superior strength, and other benefits reviewed here in our comparison chart.

How to Improve Bearing Selection? Consider a FEA Report!

One of the functions I’ve really enjoyed in my new position here at TriStar is collaborating with our clients to help them improve their bearing selection. In many cases, this involves moving beyond understanding just the load, speed and other basic application requirements and expanding into solid modeling techniques. At TriStar, we often incorporate a solid modeling finite element analysis (or FEA) report into the bearing selection process. Not familiar with FEA or how it can predict bearing material performance?

TriStar University Videos: Rulon Bearings & Surface Modification 101

You may know that Rulon bearings are a superior mix of PTFE materials, and that TriStar is the exclusive North American distributor. But do you know the history of Rulon, or the most-common formulas? 

What about surface modification? Would you like an in-depth review of the various techniques?

As graduation season nears, the professors at TriStar University (our very-own engineering experts!) have a host of videos for you to explore – all tuition-free, and no thesis required!

Plastic Agriculture Bearings Are Green for Earth Day

In honor of Earth Day this month, we wanted to give a shout out to plastic agriculture bearings; the green way to power the tractors, backhoes and seeders of the farming industry. The industry as a whole is facing increased mandates for clean and organic, and greaseless plastic bearings are delivering by reducing field contamination and increasing fuel efficiency.
