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:
Rulon 1439 is an excellent material for submerged applications, as it is compatible with most lubricants and delivers better wear than most PTFE compounds. The material resists boiling temperatures and caustic washdown chemicals of FDA-compliant environments, plus it has a pleasing, stain-resistant white color. Rulon 1439 is an excellent replacement steady bearing in food processing mixing applications.
