In sensitive food-grade applications and corrosive environments, choosing the right bearings is essential to ensure long-term system performance and reliability. Bearings must be able to withstand harsh conditions without requiring frequent maintenance or replacement.
Over time, bearing manufacturers have developed specialized solutions designed to handle the wear and tear associated with constant exposure to corrosive elements or high-pressure washdowns. These innovations help maintain performance and reduce downtime in demanding settings.
For example, stainless steel bearings, sealed designs, and solid lubricants can be used to create components that deliver exceptional durability while resisting contamination. At Emerson Bearing, we are proud to offer the NTN Sentinel Series stainless steel bearings, which are specifically engineered for use in food-grade environments.
Features and Benefits
The NTN Sentinel Series bearing units are designed with food-grade solid lubricant and safety-focused covers, providing maintenance-free operation that reduces downtime and improves cost efficiency. The NSF H1-certified solid lubricant eliminates the need for reapplication after installation and is resistant to washdowns, making it ideal for hygiene-critical food and beverage applications.
A combination of seals and slingers creates a washdown-resistant barrier, helping prevent contamination. The fully stainless-steel construction also enhances resistance to chipping and corrosion, reducing the risk of part breakdown and potential contamination. Protective covers add an extra layer of defense against moisture and contaminants, while also safeguarding maintenance personnel.
These bearings are easy to install and serve as an excellent upgrade for older, less reliable bearing systems.
Understanding Food-Grade Solid Lube
Food-grade solid lubricant is a polymer-based product infused with safe oil, suitable for temperatures ranging from 14°F to 212°F. This type of lubricant is stored in a porous material that acts like a sponge, releasing only the necessary amount of oil to keep moving parts properly lubricated. This ensures continuous lubrication, extending bearing life and minimizing maintenance needs.
Because the lubricant is contained within the material, it remains unaffected by high-pressure washdowns, staying intact and effective. Additionally, the seal and slinger design prevents leaks that could attract dust and dirt, maintaining cleanliness around the bearing.
Common Applications
Beyond food-grade settings, the NTN Sentinel Series is also well-suited for corrosive environments due to its robust sealing system. These bearings are widely used in industries where direct or incidental contact with food occurs, such as:
- Conveyors
- Bottling and canning
- Dairy processing
- Seafood and meat processing
- Cosmetics and pharmaceutical production
They are particularly effective in blending, stirring, separating, cooking, drying, packaging, and wrapping applications. Their maintenance-free design makes them ideal for hard-to-reach or difficult-to-access areas, eliminating the need for regular servicing after installation.
