Food-grade environments require bearing units specifically designed to adhere to exacting standards. NTN’s Sentinel Series provides peace of mind in environments where moisture, cleaning agents and other contaminants run rampant. Our corrosion resistant design shields against all of these problems and our food-grade solid lube withstands the high pressure sanitation and washdown procedures necessary in these environments.

2. 100% stainless steel bearing are corrosion-resistant and require no coating, eliminating the potential of flaked coatings contaminating end product
3. Silicone seal and slinger combination creates a water-resistant barrier to help prevent contamination
4. Protective covers for units provide additional protection against contaminants and moisture, while adding additional safety for maintenance personnel
5. Full-contact nitrile seals creates a water-resistant barrier to help prevent contamination
