Core processing equipment of food and beverage industry such as beverage filling machines, sterilizers, pasteurization equipment, food chain conveyors, packaging machines, washing machines and dairy production lines operate under special working conditions of frequent high-pressure cold/hot water flushing, acid-base disinfectant spraying, high-humidity vapor environment, alternating cold and hot temperature and continuous operation under medium and light loads. The food and beverage industry implements strict hygiene control standards, and production lines require regular comprehensive cleaning and disinfection. Once bearing sealing fails, washing water and disinfectant penetrate into the interior. It will not only cause bearing rust and seizure, but also grease leakage brings risks of food contamination and food safety hazards. Ordinary cylindrical roller bearings cannot adapt to washing conditions in food workshops. Daily CIP/SIP on-site cleaning operations enable high-pressure water to easily break through simple seals and enter bearing cavities. Grease emulsifies and runs off upon contact with water, leading to rapid bearing abnormal noise and rust. Disinfectants contain weak acid and weak alkali components. Ordinary steel has insufficient corrosion resistance, resulting in pitting corrosion and rust spots under long-term spraying and accelerating raceway wear. Large temperature difference between day and night in workshops causes water vapor condensation inside bearings and aggravates corrosion. Conventional grease fails to meet food contact standards, bringing compliance risks in case of leakage. Frequent bearing damage requires shutdown and replacement, disrupting continuous production schedules. Cleaning and disassembly take a long time, greatly increasing enterprise operation and maintenance costs, and bringing pressure on hygiene management, which becomes a widespread equipment pain point in the food and beverage processing industry.

Focusing on hygienic transmission equipment for food industry, Japan NMT specially develops washable corrosion-resistant hygienic long-life cylindrical roller bearings dedicated for food and beverage machinery to solve industry pain points of ordinary food machinery bearings such as poor wash resistance, easy corrosion, non-compliant lubrication, easy water ingress during cleaning and frequent maintenance shutdowns. Through five core upgrades including corrosion-resistant stainless steel base material, multi-layer hygienic waterproof sealing, food-contact qualified lubrication system, surface passivation anti-corrosion technology and wide-temperature stable structure, it fully adapts to humid conditions with frequent cleaning of filling, sterilizing and conveying equipment. It fundamentally solves problems including bearing rust caused by water ingress, lubricant leakage and corrosive wear, meets food industry hygiene specifications, and provides clean and reliable core transmission support for automatic food and beverage production lines.

Core Product Advantages

1. Corrosion-resistant stainless steel base material resists disinfectant erosion: Adopting special high-corrosion-resistant stainless steel for food equipment with reinforced passivation treatment. It withstands long-term erosion by weak acid, weak alkali disinfectants and condensed water, and resists pitting corrosion and rust spots, adapting to hygienic production environments with frequent spray cleaning.

2. Multi-layer hygienic waterproof sealing blocks high-pressure washing water: Equipped with exclusive multi-layer waterproof composite sealing structure for food working conditions, resistant to high and low temperature hot water flushing. It effectively blocks intrusion of high-pressure washing water, disinfectant and water vapor into bearings, prevents grease emulsification by water absorption and lowers internal corrosion risks.

3. Food-grade compliant lubrication system eliminates contamination risks: Matched with long-life grease complying with food contact standards, featuring excellent hydrolysis resistance and low leakage. Even tiny leakage meets sanitary regulations, effectively avoiding product pollution risks and adapting to production lines with regular CIP and SIP cleaning.

4. Surface passivation protection technology improves cleaning durability: Precision passivation treatment is applied on bearing inner and outer rings and rolling elements to seal microscopic pores on metal surfaces, reduce adhesion and penetration of cleaning media, slow down corrosion and extend bearing service life under humid and frequent washing conditions.

5. Wide-temperature stable structure ensures smooth operation under alternating cold and heat: Optimizing internal clearance ratio and roller arrangement to adapt to alternating high sterilization temperature and normal production temperature. Jamming and vibration rarely occur with temperature fluctuation, stabilizing operation of filling and conveying equipment and reducing defective filling and packaging products.
