In critical food-grade environments and corrosive conditions, choosing the right bearings is essential to ensure long-term system performance and reliability. Bearings used in these challenging settings must deliver consistent performance and durability without requiring frequent maintenance or replacement.
Over time, bearing manufacturers have developed specialized solutions designed to withstand the wear and tear caused by constant exposure to corrosive elements or high-pressure washdowns. These innovations help maintain equipment efficiency and reduce downtime in demanding applications.
For example, stainless steel bearings, sealed with solid lubricant, and equipped with protective seals and slingers can be customized to create components that perform exceptionally well and last longer while resisting contamination.
At Emerson Bearing, we are proud to offer the NTN Sentinel Series stainless steel bearings, specifically engineered for use in food-grade environments where hygiene and safety are top priorities.
**Features and Benefits**
The NTN Sentinel Series bearing units feature food-grade solid lubricant and safety-focused covers, making them ideal for maintenance-free operation. This design helps reduce downtime and lower overall costs.
The NSF H1 food-safe solid lubricant eliminates the need for reapplication after installation. Additionally, these bearings are resistant to washdowns, making them suitable for the rigorous cleaning processes required in food and beverage production.
A combination of a seal and slinger creates a washdown-resistant barrier, helping prevent bearing contamination. The fully stainless-steel construction further protects against chipping and corrosion, which could otherwise lead to contamination from component failure. Protective covers also add an extra layer of defense against moisture and dirt, while ensuring the safety of maintenance personnel.
These bearings are easy to install and serve as an excellent replacement for older, less reliable bearing systems.
**Understanding Food-Grade Solid Lube**
Food-grade solid lubricants, such as the NSF H1-rated type used in the NTN Sentinel Series, are made from a polymer infused with safe oil. They operate effectively between 14°F and 212°F, making them suitable for a wide range of food processing applications.
The oil is stored in a porous material that acts like a sponge, releasing only the necessary amount to lubricate moving parts continuously. This ensures consistent lubrication, extending bearing life and minimizing the need for maintenance or replacements.
Since the lubricant is contained within the sponge-like structure, it remains protected from high-pressure washdowns. The seal and slinger design also prevents lubricant leakage, reducing the risk of dust and dirt accumulation around the bearing.
**Common Applications**
Beyond their suitability for food-grade environments, the NTN Sentinel Series is also ideal for corrosive settings due to its advanced sealing system.
These bearings are commonly used in industries involving direct or incidental contact with food, including:
- 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 operations. In hard-to-reach or difficult-to-maintain areas, these bearings provide a reliable solution without the need for regular servicing after installation.
