Our Advantages

  • Customization

    We provide a full-chain, one-stop non-standard bearing customization service. Our proprietary factory controls the entire process—from raw materials to final delivery—ensuring traceable quality. We develop tailor-made solutions based on customer drawings or samples, offering modifications such as heightened inner rings, grooved outer rings, and special tolerances to meet unique operational needs.

  • Quality

    We implement a full-process quality control system to ensure high precision and consistency. Utilizing specialized measuring and testing equipment, we strictly monitor key tolerances like inner/outer diameter and roundness. Every bearing undergoes standardized factory inspections—including flatness and appearance checks—with synchronized data recording to enable full traceability and prevent defect outflow, guaranteeing stable and reliable product performance.

  • Multiformity

    We have established a two-tier product system of "Proprietary Core Models + Alliance Extended Models" to meet bearing application needs across various industries. Our proprietary factory supplies 40 mature mainstream models, ensuring stable availability of standard products. Through collaboration with five partner factories, we offer an additional 230 models covering specialized categories such as non-standard customization, special materials, and high-precision bearings, fully addressing diverse and multi-batch procurement requirements.

  • Capacity

    We maintain a reliable supply system supported by proprietary production capabilities. Our dedicated factory specializes in mass-producing deep groove ball bearings, with an annual output of 13–15 million sets, enabling secure and timely bulk deliveries. Production capacity is scalable and follows a steady growth trajectory based on market demand, ensuring flexible, long-term supply support for customers.

  • Cost

    We leverage a composite supply system combining proprietary and alliance factory capacities to offer cost-effective, diversified products. Our own factory provides direct pricing advantages by eliminating middleman markups, ensuring quality and competitive prices. Through collaboration with 5 specialized alliance factories, we achieve full product coverage and enhanced efficiency, enabling flexible procurement solutions with strong price competitiveness.

Industry Applications

  • 01 / Food & Beverage Processing
    Equipment on food and beverage production lines (e.g., fillers, mixers, conveyors) comes into direct or indirect contact with ingredients. Bearings must comply with food safety regulations, resist corrosion from food acids, alkalis, fats, and steam, and be easy to clean to prevent bacterial growth.

  • 02 / Marine & Ship Engineering
    The high salinity and humidity of marine environments pose severe corrosion challenges to metal components. Marine equipment (e.g., deck machinery, pumps, thruster auxiliary units) and offshore platform equipment require bearings with excellent salt spray corrosion resistance, anti-rust capability, and high load-carrying reliability.

  • 03 / Medical & Pharmaceutical
    Medical devices (e.g., dental handpieces, centrifuges, imaging equipment) and pharmaceutical machinery (e.g., filling lines, mixers) require bearings with exceptional cleanliness, precision, low noise, and long service life. Many applications involve frequent high-temperature, high-pressure sterilization, with zero tolerance for contamination risk.
    View More
  • 04 / Chemical & Electroplating
    Equipment in this industry is frequently exposed to strong acids, alkalis, solvents, and other highly aggressive chemical media. Standard bearings are highly susceptible to corrosion and rapid wear, leading to equipment failure, downtime, and even safety hazards.
    View More
  • 05 / Water Treatment
    In wastewater treatment, desalination, pump systems, and water circulation equipment, bearings are consistently exposed to moisture, corrosive chemicals (e.g., chlorine, flocculants), and abrasive particles. This demands exceptionally high sealing, corrosion resistance, and wear resistance from the bearings.
