Q&A: Can Rulon Be Used in a Liquid Application? [VIDEO]

March 7, 2017

Rulon W2 vs. Rulon 1439 in Liquid Applications

In our last post, we reviewed the connection between PTFE and high temperatures. Today we explore if Rulon (a PTFE derivative), is compatible with a liquid bearing application. And the answer is that yes, Rulon is compatible with liquids, but special attention must be paid to the type of liquid, as well as the type of filler. Here are two Rulon options we often recommend:

Rulon Bearings for Mining Machinery:  Low Maintenance and High Efficiency

October 11, 2016

Rulon Bearings for Mining Machinery

I read a great article on mining.com this week about how the global mining market is booming. Sales of underground mining equipment are expected to reach $30.5 billion by 2023. But what really stood out to me was the fact that “companies are replacing outdated machinery with more energy efficient solutions.” Did you know that Rulon bearings are energy efficient and versatile ― especially when compared to bronze bushings? Let’s review:

A Fabrication Success Story:  How Rulon Solved an Injection Molding Defect

September 27, 2016

Rulon 945 -Injection Molding

Today we share a success story starring Rulon as a replacement for polyimide in an injection molding application. Our partner makes industrial molding equipment, everything from machines to molds and all accessories. They had a problem where the injection nozzles left defects behind on the newly-injected plastic parts. As their scrap pile mounted, and profits fell, they changed their nozzle tip insulators to Rulon 945. Problem solved and profits soared. Here’s how Rulon 945 did it:

Storage of Rulon: How long will the material last?

I’m just returning to the office after a week of customer site visits. And one question that I was asked repeatedly involved the storage of Rulon. How long will Rulon materials really last? Theoretically, the material can last indefinitely – if it is handled and stored under the right conditions. To extend the lifespan of your Rulon plastic materials, we recommend that you look at these key storage factors...

Rulon Bearings Go Green for Paper and Lumber Industries

August 5, 2014

Rulon Bearings Go Green for Paper & Lumber IndustriesGrease-free and long-lasting, self-lubricating bearings are the green choice for use on the equipment used to harvest and process lumber and paper products. But the green factor took on a whole new meaning recently when we partnered with a Northwest paper manufacturer who operates a completely self-sustaining plant.

Aircraft Bearings: Polymer pivots, steers and lifts with better performance

July 9, 2014

Aircraft Bearings: Polymer pivots, steers and lifts with better performanceHistory was made last month in the aviation industry as Boeing delivered its 1,500th 747 aircraft – the first wide-body airplane to reach this delivery milestone.  As a longtime provider of bearings for aircraft ranging from helicopters to military jets and even space components, TriStar shared in the marvel of the moment.

Aircraft bearings have strict requirements for quality and performance; they must tolerate massive fluctuations in temperatures, pressurized cabins, all-weather conditions, plus extreme loads.   And polymer bearings are becoming the go-to material for lift, tilt and pivot points in the steering, fuselage, wings and other areas of commercial aircraft.   Unlike metal bearings, they provide self-lubricating service to save on greasing and maintenance costs.  Here’s a sampling:

Rulon 641: Performance from Food Processing to Medical Equipment Manufacturing

April 9, 2014

Rulon 641 has USP Class VI approval for medical applications.The food and medical manufacturing industries share many commonalities; most notably, they operate in environments with strict regulations for quality, safety and sanitation.  Processing equipment must be of the highest quality and offer contamination resistance.  Rulon® 641 is the only FDA-cleared material for use in food processing that also has USP Class VI approval for medical applications.

Two demanding manufacturing environments, one common material ― Rulon 641.  See our Rulon Comparison Chart to explore the advantages.
