Ensure Your Food Processing Bearings And Components Are Ready For Anything
Tuesday, December 29, 2009 at 01:36PM By Stephanie A Eldred
Do the bearings used in your food processing environment offer protection from:
- Oil leakage?
- Regular washdowns?
- Chemical presence?
- Temperature fluctuations?
- Contamination?
They should. To qualify for use in the food and beverage industries a bearing must be able to withstand attack from all sides. That said, bearings designed for use in food processing are designed to address specific environmental conditions, so understanding processing environments and the component types best suited to them is vital.
MATERIALS
For resistance to heat fluctuations and environmental contaminants, bearings used in food or beverage applications require superior materials to perform optimally. Bearings made with stainless steel, for example, offer the best protection from corrosion, whether from washdowns, chemical contamination or product wear and tear that may result in peeling paint or general corrosion. Other viable choices include chrome and nickel alloy coated bearings which are particularly well suited to extreme conditions that include heat, moisture and chemicals.
PROTECTORS AND INSERTS
Protectors are designed to cover shaft ends, which secures both safety and contamination resistance. Bearing inserts are wide inner ring ball bearings that are factory charged with grease and effectively sealed. Most units also have re-lubrication facilities that may be required if the units are operating in arduous conditions.
LUBRICATION
Regardless of the choice of bearing, grease used in food and beverage applications must meet regulatory standards. Molded oil bearings are a superior option for food processing applications as they eliminate the need for re-lubrication, negate leakage risks and are appropriate for totally immersed conditions.
HIGH TEMPERATURE ENDURANCE
With shifts in temperatures common in the food industry, bearings must be treated to endure varying heat exposure. Standard bearings will have a higher failure rate than those specifically designed to handle extreme conditions.
Food processing applications have a unique set of bearing requirements that must be satisfied to ensure maximum uptime and reduced maintenance. With the superior innovation at NSK, let us help you assess your needs and suggest the best products for your business.
