The food, pharmaceutical and aquatic processing industries implement strict sanitation management standards. Production equipment needs regular comprehensive flushing with clean water and disinfectants. Ordinary steel bearings are prone to rust after long-term contact with moisture and disinfectant solutions. Falling rust debris will directly contaminate raw materials and finished goods, lead to product scrapping and cause massive economic losses. Clean production lines prohibit lubricants that may release pollutants. Most equipment runs continuously at low speed for long hours, so bearings must maintain stable performance under conditions with limited lubrication and potential dry friction. Many filling and conveying equipment feature compact space and complicated component disassembly. Premature corrosion damage of bearings leads to frequent shutdown for cleaning and replacement and disturbs the whole production schedule. The market urgently demands special stainless steel bearings with hygienic material, resistance against water washing and corrosion, and adaptability to clean manufacturing environments.

NMT Stainless Steel Bearings are forged and processed with corrosion-resistant stainless steel. The stable metal structure resists oxidation and rust even with long-term exposure to water vapor and disinfectants, effectively preventing material contamination caused by rust particles. Precision polishing is adopted during production. Raceways of inner and outer rings as well as rolling elements have smooth surfaces to reduce residue adhesion and facilitate daily washing and cleaning of equipment. The bearings can work with food-grade lubricants without separating harmful substances, complying with hygiene regulations for food and pharmaceutical sectors. Optimized internal structure maintains low operating friction even with insufficient grease supply and restrains abnormal temperature rise and noise. Various sealing types are optional to block production residues and cleaning waste liquid from entering raceways and slow down abrasion and corrosion. Standardized overall dimensions deliver excellent universality. Large structural modification is unnecessary during upgrading and replacement of old and new food processing and filling machinery.

Open type and sealed type are available and compatible with food-grade grease. Selection can be made according to washing frequency, corrosiveness of medium and rotating speed for all kinds of clean production equipment requiring regular washing and disinfection.
