Reinventing the (Mouse) Wheel with Rulon Bearings

Every so often, we’re called upon to work on a one-of-a-kind bearing application. This was the case recently when we partnered to develop wheel bearings for a lab testing device for mice and rats. Here’s how we helped our client “build a better mousetrap” (so to speak) with the help of Rulon J!

What do a Telescope, a Volcano and Rulon J have in Common?

What do a Telescope, a Volcano and Rulon J have in Common?

The answer is an out-of-this-world application solution! Every once in a while, an extremely unique application comes through the TriStar shop, and this Rulon J application was it! 

This project involved choosing a durable slide-pad material for one of the world’s largest telescopes. But this telescope had an extreme location in an observatory 14,000 feet above sea level, atop a dormant volcano ― in Hawaii! Bearing requirements called for slide pads that could tolerate extreme altitude and atmospheric pressure. The material also had to deliver prolonged wear in temperatures ranging from -10° to +10°C with extreme UV exposure.

Here’s why low-friction Rulon J was selected over other bearing materials:

Rulon J vs. Teflon: An Aerospace Application

September 22, 2015


Takeoffs and landings, friction and fatigue, these are just a few of the demands on aerospace bearings. Should designers choose Rulon J tape or Teflon® tape for an aerospace bearing application? Which material can resist the challenges of wear and corrosion in aerospace and aviation? We tested both materials, and this is what we found.

Want to Extend Bearing Service by 3x? Install Genuine Rulon J!

June 18, 2015

Rulon J replaced the failing bearings on the DC drive air compressor units of off-road autos.

Did you read our recent post about the seizure of thousands of fake bearings that were bound for US automakers? Counterfeit versions of Rulon J and other bearings remains a real industry challenge ― a fact I was reminded of when we helped a client extend the lifespan of their auto components by 3x with genuine Rulon J. This huge gain in productivity could not have been accomplished with lower-quality, counterfeit materials.

Rulon J Eliminates Stick/Slip in Military Rifles

October 2, 2014

Rulon J Eliminates Stick/Slip in Military RiflesWith a client base covering more than 70 industries, there is never a dull day in the TriStar labs. But occasionally, a unique application comes along that stands apart from the rest. This was the case when we solved a “sticky” situation for a 50-caliber semi-automatic rifle. The challenge was in sourcing a lightweight, durable trunnion bearing that would allow for smooth shooting and movement of a remote weapon in an active military zone. And Rulon J fit the bill.

Rulon Reels In Custom Fishing Components

August 28, 2014

Rulon Reels In Custom Fishing ComponentsHere’s a fishing tale about the one that didn’t get away! 

Our team worked with a high-end fishing manufacturer to design a whole new reel drag system. The drag is actually a slip-clutch assembly that allows the line to move freely under the pressure of a sudden hook or the pull of a large fish ― basically keeping the fish engaged while the line is hauled in. 

Why did we choose Rulon LR and Rulon J formulas for this unique clutch application? It all came down to matching the right compounds to the right surface materials.

Rulon J and Adhesion: With or without Plasma Surface Modification?

August 21, 2014

Rulon J - Pull Strength - Untreated vs. TreatedToday’s question of the day is brought to you by the TriStar team: What are the differences in adhesion between Rulon J that has been treated with Plasma Surface Modification vs. the adhesion properties without treatment? 

We recently conducted a survey in our lab and I wanted to share the results with you! Our study examined the adhesion compatibility of Rulon J, which is one of the original Rulon compounds and is known for good wear and friction properties. Here’s what we uncovered:

Rulon Bearings: How to Recognize Genuine and Avoid Counterfeit!

May 16, 2014

Rulon Bearings White PaperIt’s here - our latest Rulon® White Paper!

Did you know that not all bearing materials are created equally - not even those sold under the same brand name?  The truth is that there’s a flood of low-quality, counterfeit bearing materials being sold under the Rulon® brand name.  For most manufacturers it can be difficult to decipher genuine materials from counterfeit, yet counterfeit materials can be devastating to your application.

Rulon Bearings: A Review of Common Formulas

April 17, 2014

Rulon 641 is FDA-cleared for use in food and pharmaceutical applicationsRulon® is one of the materials that we are asked about most often.  While there are over 300 unique formulas of this material, today we’ll review some of the most-common formulas.  No matter which formula your application requires, you should expect a versatile, self-lubricating, and low-friction material for bearings, seals, gaskets and structural components.
