NMT Stainless Steel Bearings Corrosion-Resistant Low-Noise Transmission Bearings For Humid And Seawater Working Conditions
Equipment in food, aquatic product and water treatment industries works in long-term high-humidity conditions, frequently exposed to clean water, cleaning agents and seawater mist. Ordinary steel bearings are prone to rust. Rust increases rolling resistance, causes abnormal noise and jamming, and leads to unexpected shutdown. Many food processing facilities have strict hygienic standards. Bearings shall not produce rust debris which may contaminate products. Frequent water washing also puts forward strict requirements on anti-corrosion performance. Outdoor light machinery suffers rain and temperature changes all year round. Bearings without proper protection require frequent replacement and raise operation costs. The market demands stainless steel bearings with corrosion resistance, smooth rotation and hygienic property.
NMT stainless steel bearings adopt high-quality stainless steel. Rings, rolling elements and cages are made of matched anti-corrosion materials to resist damage from vapor, weak acid, alkali and salt water. Precisely ground raceways reduce rolling friction and operating noise. Various sealing structures prevent washing liquid and contaminants from entering and diluting grease. The bearings can be filled with food-grade lubricant to meet clean production standards. Stable structure enables adaptation to continuous normal-temperature operation and intermittent washing. Standard dimensions support direct replacement without structural modification of machinery.
Multiple types including open and sealed versions with grease lubrication are available. Configurations can be selected according to corrosion level and cleaning frequency for intermittent or round-the-clock operation.
