In food-grade applications and environments prone to corrosion, choosing the right bearings is essential for ensuring long-lasting system performance and reliability. In such demanding conditions, bearings must deliver superior performance and durability without requiring frequent maintenance or frequent replacements.
Over the years, bearing manufacturers have developed innovative solutions tailored to withstand the usual wear and tear encountered in applications exposed to corrosive substances or subjected to rigorous high-pressure washdowns. For example, stainless steel bearings, solid lubricants, and seals or slingers can be employed to build specialized components that offer extended service life and resistance to contamination.
At Emerson Bearing, we're proud to offer the NTN Sentinel Series of stainless steel bearings, specifically engineered for use in food-grade settings.
With features like food-safe solid lubricants and safety-focused covers, the NTN Sentinel Series bearings are designed to provide maintenance-free operation, minimizing downtime and maximizing cost efficiency.
The NSF H1-certified food-safe solid lubricant eliminates the need for reapplication post-installation. Additionally, these bearings are resistant to washdowns, making them suitable for the regular cleaning required in hygienic food and beverage applications.
A seal and slinger combination creates a robust barrier against washdowns, preventing bearing contamination. The 100% stainless steel construction further aids in preventing chipping and corrosion, reducing the risk of contamination from component degradation. Protective covers add an extra layer of protection against moisture and contamination while safeguarding maintenance personnel.
These bearings are easy to install and make an excellent replacement for outdated or underperforming bearing systems.
Understanding Food-Grade Solid Lubricants
Food-safe solid lubricants, made from a polymer infused with food-grade oil, can operate effectively in temperatures ranging from 14°F to 212°F, making them ideal for various food applications. The oil is housed in a porous material that acts like a sponge, releasing only the necessary amount of base oil to keep components moving smoothly. This ensures continuous lubrication, extending bearing life and reducing the need for maintenance and replacements.
Since this lubricant is contained within the sponge-like structure, it doesn't come into contact with high-pressure washdowns, which are crucial for removing contaminants. The H1 solid lubricant remains intact and functional even under intense washdown conditions. Moreover, the seal and slinger design prevent any risk of lubricant leakage, which could otherwise attract dust and dirt around the bearing.
Common Applications
Beyond their suitability for food-grade applications, the NTN Sentinel Series bearings excel in corrosive environments due to their unique seal and slinger design. These bearings find use in sectors where there’s direct or incidental contact with food, including:
- Conveyors
- Bottling/Canning
- Dairy Processing
- Seafood and Meat Processing
- Cosmetics and Pharmaceutical Production
Sentinel bearings are particularly well-suited for blending, stirring, separating, cooking, drying, packaging, and wrapping operations within these industries. Hard-to-reach or difficult-to-maintain locations can significantly benefit from these bearings, given their low-maintenance and long-lasting nature.
