→PRODUCT INTRODUCTION


echnical Specifications of Silicon Nitride (Si₃N₄) Ceramic Balls

  1. Advanced Manufacturing via Hot Isostatic Pressing (HIP)
    • Precision Fabrication: Our silicon nitride ceramic balls are produced using Hot Isostatic Pressing (HIP) technology, a high-pressure sintering method that ensures ultra-high density (≥99.5%) and minimal porosity.
    • Enhanced Performance: HIP eliminates microcracks and achieves uniform grain structure, resulting in superior mechanical properties (e.g., hardness ≥1600 HV, fracture toughness ≥6 MPa·m¹/²) and thermal stability (operating up to 1300°C).
    • Application Suitability: Ideal for high-speed, high-load applications such as aerospace bearings, precision machinery, and semiconductor equipment where reliability under extreme conditions is critical.
  2. Certifications & Compliance
    • Schaeffler Certification: Verified to meet Schaeffler Group standards (e.g., ISO 3290, DIN 5401), ensuring dimensional accuracy (tolerances per ABEC 7/11) and surface finish (Ra ≤0.005 μm).
    • Google-Compliant Specifications: Aligned with Google’s sustainability and performance benchmarks, featuring low friction coefficients (μ ≤0.15), corrosion resistance, and compatibility with eco-friendly lubricants.
    • Global Adoption: Trusted by industries including automotive, robotics, and renewable energy for long-term durability and energy efficiency.

Key Advantages:

  • Lightweight Design: 30% lighter than steel balls, reducing inertia and energy consumption.
  • Chemical Inertness: Resistant to acids, alkalis, and oxidation.
  • Scalability: Customizable sizes (⌀1 mm to ⌀50 mm) and coatings (e.g., DLC for enhanced wear resistance).

This Si₃N₄ ceramic ball combines cutting-edge HIP technology with rigorous industry认证, delivering unmatched performance for modern engineering challenges.

→COMPANY PROFILE

12.jpg

Wuxi Xinwei Rolling Element Manufacturing Co., Ltd. is dedicated to the research, development and production of bearing-related products. Since its establishment, the company has always adhered to the concepts of innovation and giving top priority to quality, gradually making a name for itself in the industry.

The company mainly produces silicon nitride bearing ceramic balls, silicon nitride rollers and ceramic bearings. By adopting the advanced hot isostatic pressing technology, it ensures that the products have a uniform internal structure and stable performance. The large-circulation grinding process effectively improves the product precision and reduces the surface roughness. Thanks to the application of these two core technologies, the products have a much higher cost-performance ratio than those of peers, winning the recognition of well-known companies such as Schaeffler.

In terms of application fields, the company's products are widely used in wind power generation bearings, contributing to the development of the clean energy industry. They can meet the requirements of lightweight and high performance for drone bearings. They are also suitable for new energy vehicle bearings, providing a reliable guarantee for green travel. In high-precision grinding machine bearings, they also ensure the stable operation of the grinding machines with their excellent performance.
