  • Stainless Steel Ball Bearings

    Stainless steel bearings are widely used and have advantages over regular bearings due to their corrosion resistance, acid-alkali resistance, rust prevention, and wide temperature range applicability. They find applications in environments with complex and harsh conditions such as food processing machinery (juicers, food mixers), household appliances, medical equipment, and other demanding fields.
    NBVO currently produces stainless steel bearings that meet V2 and V3 levels. 
    Key technologies include:
    Precision Level P5: Improving machining processes, incorporating additional heat treatment quenching followed by cold treatment at temperatures of -75 to -80 ℃ for 1 to 1.5 hours to ensure high dimensional stability of the inner and outer rings.
    Low Noise: Employing a dual-stage groove process using imported oil stones to maintain machining benchmarks, enhancing roughness of the inner and outer ring channels, ultimately maintaining stainless steel bearing noise within the Z2 range.
    Material Selection: Using highly corrosion-resistant stainless steel materials for inner and outer rings, steel balls, cages, and dust covers. SUS440 is used for inner and outer ring materials and steel balls, while SUS304 is used for cages and dust covers.
    Choosing high-purity, low-noise grease that meets food-grade certification requirements, ensuring that precision stainless steel bearings comply with international environmental standards.

Industry Knowledge Extension

Innovation and application of stainless steel ball bearings!

1. Why have stainless steel ball bearings become the "invisible guardian" of high-end industrial fields?
Stainless steel ball bearings have become core components in food processing, medical equipment, chemical industry and other fields due to their corrosion resistance, high strength and low maintenance requirements. For example, in food machinery, stainless steel can avoid contamination of products due to rust, and Ningbo NBVO Seiko Bearing Co., Ltd has further improved the durability and hygiene standards of bearings through SUS304/316 stainless steel materials and precision manufacturing processes.

2. How does NBVO define the "precision ceiling" of stainless steel bearings through technological innovation?
NBVO uses modern high-precision equipment and precision processes of level 6 and above to produce deep groove ball bearings with noise levels of ZV3 (stainless steel) and ZV4 (chrome steel). Its patented technologies such as **"bearing polishing fixture" and "grinding device"** significantly reduce processing deflection and ensure the geometric accuracy of the inner and outer rings of the bearings by optimizing clamping stability and grinding efficiency.

3. How to achieve low noise performance of stainless steel ball bearings? What does this mean for industrial applications?
Low noise bearings need to make breakthroughs in three aspects: material purity, raceway smoothness and assembly accuracy. NBVO reduces steel impurities through vacuum degassing smelting technology, combined with fully automatic grinding equipment and acoustic detection systems, so that product noise control reaches the industry-leading level. This feature enables it to greatly reduce vibration interference in scenarios such as motors and precision instruments, and improve equipment life.

4. From international certification to market competitiveness, what is NBVO's "quality code"?
The company strictly follows global standards such as ISO 9001:2015 and IATF 16949:2016, and has passed ROHS and REACH environmental certifications to ensure that its products meet EU environmental protection requirements. Its core advantage lies in the **"high cost-effectiveness"** strategy - using automated production lines to reduce manufacturing costs while maintaining the performance stability of precision bearings, becoming the preferred supplier of domestic and foreign automobile and CNC machine tool manufacturers.

5. How will stainless steel bearings break through application boundaries in the future? What insights does NBVO's technical layout give?
With the growing demand for extreme temperature resistance and lightweight bearings in emerging fields such as new energy and robots, NBVO has laid out low-temperature resistant lubrication technology and thin-walled bearing research and development. Its patented achievements, such as the "adjustable linkage grinding device", not only improve production efficiency, but also provide technical reserves for customized bearing development, and promote the industry to upgrade to intelligence and greenness.
