  • Stainless Steel Ball Bearings
    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.

  • Flange Deep Groove Ball Bearings
    Flange Deep Groove Ball Bearings
    Flange Deep Groove Ball Bearings represent a specialized and crucial category within the realm of ball bearings, engineered to meet specific industrial requirements. Characterized by their distinctive flanged outer rings, these bearings are designed to provide enhanced axial stability and support in applications where precise axial positioning is essential.
    The flange, a rim or lip projecting from the outer ring, serves multiple purposes. It acts as a built-in shoulder, preventing axial movement of the bearing in one direction and facilitating proper alignment within the machinery. This design feature is particularly advantageous in applications where space is limited or when a separate housing is unnecessary.
    These bearings excel in accommodating both radial and axial loads, making them versatile components in a variety of machinery, including motors, gearboxes, and conveyor systems. The deep groove geometry of the ball bearings ensures efficient distribution of loads and promotes smooth operation with reduced friction.
    We use high-quality materials and advanced manufacturing techniques to ensure durability and reliability. Flange Deep Groove Ball Bearings play a pivotal role in maintaining machine precision, minimizing vibrations, and contributing to the overall efficiency and longevity of mechanical systems across industries. Their innovative design makes them indispensable in applications where space optimization, axial support, and reliable performance are paramount.

  • Single Row Deep Groove Ball Bearings
    Single Row Deep Groove Ball Bearings
    Single-row deep groove ball bearings are widely used in the world due to their versatility and overall performance. They are characterized by having deep raceway grooves in which the inner and outer rings have circular arcs of a slightly larger radius than those of the balls. They also have non-separable rings. Their straightforward basic design has many advantages:
    1. High Speed 
    2. Low noise 
    3. Good radial load capacity
    4. Have low torque capacity at startup and running speeds
    Single Row Deep Groove Bearings stand as foundational components in precision engineering, embodying simplicity and efficiency in their design. With a solitary row of uniformly spaced, deep raceway grooves on their inner and outer rings, these bearings are adept at handling radial loads and moderate axial loads in both directions.
    The deep groove structure of these bearings enables them to accommodate a wide range of applications across various industries, from automotive systems to industrial machinery. The inherent geometry of the deep grooves ensures the distribution of forces, reducing friction and promoting smooth rotation. This makes them ideal for applications demanding high-speed operation and precise performance.
    The simplicity of the single-row design not only enhances the bearings' cost-effectiveness but also facilitates ease of installation and maintenance. Engineers often rely on these bearings for their versatility, as they can operate efficiently in diverse conditions, ranging from low to high temperatures.
    Manufactured with precision and utilizing high-quality materials, single-row deep groove bearings play a pivotal role in supporting rotating elements, ensuring the reliable and continuous operation of machinery. Their widespread use underscores their significance as fundamental components that contribute to the efficiency and longevity of various mechanical systems.

  • Hybrid Ceramic Bearing
    Hybrid Ceramic Bearing
    Hybrid Ceramic Bearings represent an innovative evolution in bearing technology, merging the advantages of traditional steel bearings with the properties of ceramic materials. These bearings feature ceramic rolling elements, typically made from materials like silicon nitride, while the inner and outer rings are typically constructed from conventional steel.
    The incorporation of ceramic rolling elements provides several key benefits. Firstly, ceramics have a higher hardness and lower density compared to steel, resulting in reduced friction and improved wear resistance. This characteristic contributes to lower operating temperatures and enhanced durability, making hybrid ceramic bearings particularly well-suited for high-speed applications where heat generation and wear are critical factors.
    The combination of ceramic balls with steel rings also offers advantages in terms of weight reduction, contributing to overall system efficiency. Furthermore, ceramic materials exhibit resistance to corrosion and are less susceptible to the effects of harsh environments, extending the lifespan of the bearing and minimizing maintenance requirements.
    Hybrid Ceramic Bearings find applications in diverse industries, including aerospace, automotive, and industrial machinery, where the demand for increased performance, reliability, and longevity is paramount. While these bearings may command a higher initial cost, their long-term benefits in terms of reduced friction, extended service life, and improved efficiency make them a preferred choice for critical and demanding applications.

  • Thin Section Ball Bearings
    Thin Section Ball Bearings
    NBVO Thin section ball bearings are precision-engineered bearings designed with a slim cross-section, making them ideal for applications where space is limited and weight is a concern. These bearings consist of a ring with a groove that houses a set of balls, allowing for smooth rotation and minimal friction. They are commonly used in industries such as aerospace, robotics, medical equipment, and semiconductor manufacturing.
    One of the key advantages of thin section ball bearings is their compact design, which enables them to fit into tight spaces while still providing high performance. This makes them particularly useful in applications where traditional, bulkier bearings would be impractical.
    Thin section ball bearings are available in various sizes and configurations to suit different applications and load requirements. They are typically made from high-quality materials such as stainless steel or chrome steel to ensure durability and reliability in demanding operating conditions.
    Thin section ball bearings offer a combination of space-saving design, precision engineering, and reliable performance, making them essential components in many modern mechanical and electromechanical systems.

  • Full Ceramic Ball Bearings
    Full Ceramic Ball Bearings

    Full ceramic bearings have the characteristics of non-magnetic electrical insulation, wear resistance, corrosion resistance, oil-free self-lubrication, high temperature resistance, low temperature resistance, etc., and can be used for extreme evil and special working conditions.

    NBVO's full ceramic ball bearings constructed entirely of ceramic material. Inner/outer races and balls are made of either Silicon Nitride (Si3N4), Zirconium Oxide (ZrO2) or Silicon carbide (SiC). They are available as full complement (no cage) or with a cage made from PEEK or PTFE. Full ceramic bearings are for medium load and medium speed applications. It is not possible to achieve the inner and outer ring roundness that is found with precision steel bearings so full ceramic bearings have lower speed ratings.
