January 19, 2016

How does brinelling cause bearing failure in metal?

How does brinelling cause bearing failure in metal?

Some of our best questions come directly into our Ask the Experts portal, and this one is a prime example. Today, we review brinelling, which is a key cause of bearing failure in metals. Along with lubrication, fatigue, and corrosion, brinelling failure causes costly and premature bearing wear.

Here’s how you can avoid it.

Video  - Why Do Metal Bearings Fail? Composite bearing solutions.

Metal bearings – what causes bearing failure, really? The short answer is that there is no short answer; bearings can fail from a multitude of reasons including corrosion, fatigue, lubrication, maintenance and more. Yet whenever there’s a failure, it’s important to uncover the root cause ― but it can be a complex discovery process. 

Until now.

Q&A: How can I correct a bearing failure of agitator steady bearings?

May 7, 2015

Keep sending us your questions about bearing failure and other bearing challenges! Some of our best products were developed as a result of your toughest applications! 

This week’s question was submitted by a chemical company looking to replace their reactor agitator steady bearing used in industrial mixing and blending. The client had been using a 25% glass-filled Teflon bearing, but had a high bearing failure based on low wear properties. Add to that the fact that glass filled PTFE is not FDA acceptable and the customer had more than a wear issue. They needed a replacement bearing with FDA compliance and good friction rates. After reviewing the application, our team recommended durable, Rulon 1439 FDA-compliant steady bearings.

Rulon was chosen based on the following factors:

Bearing Materials and Tribology Testing

November 4, 2014

Blog_20141104I had an interesting conversation with a manufacturer this week regarding bearing materials and tribology testing. With so many counterfeit bearing materials on the market, it is more important than ever to ensure that you are using genuine materials before you begin manufacturing to avoid application problems down the line.

In our call we spoke of the number of processors claiming to sell quality, original materials, yet in many cases, the materials are actually a blend of poor-quality resins. To complicate the situation even further, the counterfeits often look and feel just like the real deal. How can you avoid falling victim to these lesser materials? Consider the advantages of tribology testing to guarantee true authenticity.

Common Causes of Bearing FailureWhy do bearings fail?

Unfortunately, there is not one simple, one-size fits all answer to this question. When we evaluate bearing materials for any application, we also examine why previous materials may have failed. We look at operating conditions, running temperatures, lubrication issues, fatigue factors and more to determine the root cause. It is the culmination of all of these ― plus many other factors ― that contribute to bearing service life. Here’s a quick review of common causes to help you avoid bearing failure in the future:

Tech Tip: 5 Common Signs of Bearing Failure

January 28, 2014

5 Common Signs of Bearing FailureWhy do bearings fail? This is a common manufacturing question, but one that is not always easy to answer.  Failure can be a result of many factors; extreme working conditions, maintenance and lubrication schedules, or industry-specific demands.  Early indications of bearing failure can include machinery that is running unevenly, or at an exceptionally loud volume, or with reduced accuracy. There are also some visual signs to look for.

Here are 5 common signs of bearing failure:
