Spring-energized seals can solve quite a few problems for MRO (maintenance, repair, and operations) in the food processing industry. Many of the seals used in food processing are mission critical, and a failed seal can cost much more than just repairs and downtime because it can result in contamination.

There are various challenges for designing polymer seals and bearings for the food industry, such as FDA regulations if the seal or bearing will be in contact with food products or the ability to withstand intensive cleaning and sterilization.

Food & Dairy Bearings and Bushings:
Bearings and bushings can be found in almost every step in food or dairy processing industries. Polymers are a popular choice for bearings and bushings in the food and dairy industry, both at the design stage and when retrofitting. Because they are greaseless, the can provide a more sanitary environment for food processing. They don’t require the maintenance that metal bearings and bushings require, thus reducing downtime for maintenance. Their durability results in longer mean times to failure. They are usually much more resistant to corrosion and much less chemically reactive than metal bearings and bushings. They also weight much less than equivalent metal bearings and bushings.

PTFE Rotary Lip Seal Design
When choosing a metal-cased rotary lip seal, you have many options. One design choice to be made is what material to use for the lip. Most rotary shaft seals have a lip that is made of a thermoplastic (such as PTFE, PP, or PVC), an elastomer (natural or synthetic rubber), a thermoplastic elastomer (for example, PE), or a metal. In this post, we are going to look at what makes PTFE a competitive choice for a metal-cased rotary lip seal by investigating six things your competitor’s don’t want you to know.

Polymer Seals for Food & Dairy – PTFE and UHMW
Big challenges faced in the Food and Dairy Industry
There are several major issues faced in the food and dairy industry, including:
- Temperature conditions that range from extremely high to cryogenic
- Exposure to harsh chemicals
- Excessive moisture
- Continuous sanitation regimens
- Expensive shutdowns
In these industries, simple thinks like lubrication of seals and bearings become major issues because of potential contamination. Potential contaminants in the food and dairy industry are varied, ranging from lubricants, antimicrobial barrier fluids, insects, splinters of plastic or metal, to coolants. Even contamination at the microbial level can lead to very expensive recalls.
In the food and dairy business, failure to meet both national (and international) standards can quickly destroy an otherwise successful company. It is vital that the equipment be not only reliable but compliant with governmental regulations. More and more engineers are turning to polymer options in the design and implementation of food and dairy processing equipment. This post will focus on why polymers are an outstanding option for a specific aspect of machinery used in these industries: bushings.
Why are polymer bushings a good choice?
