Food processing is one of the most heavily regulated industries. The selection of bearings and bushings for the food industry can be tough, especially when it comes to MRO.

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.

The primary purpose of a typical expansion bellows is to isolate a fluid from neighboring components. Bellows are used in a variety of applications, including pulse dampeners, HVAC systems, pharmaceutical processing, pollution control, and piping systems. PTFE (polytetrafluoroethylene, or Teflon) is an ideal material for bellows applications, and in this post we are going to explore seven things every engineer needs to know about PTFE bellows.

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?
