Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Load Handling & Rotation: Designed to manage radial and axial loads with a deep groove ball structure, enabling smooth, low-friction rotation for applications like electric motors, industrial machinery, and automotive components.
  • Durability & Protection: Stainless steel construction ensures corrosion resistance and high strength, while the rubber seal (NBR) safeguards against dust, moisture, and contaminants, extending operational life in harsh environments.

Key features

  • 1. Corrosion-Resistant Stainless Steel Construction

    • With a stainless steel outer/inner ring, you can ensure durability in harsh environments such as marine or chemical processing applications. This material outperforms standard carbon steel bearings in resisting rust and corrosion*.

  • 2. High-Speed Deep Groove Design

    • With a precision-engineered deep groove structure, you can achieve smooth, low-friction rotation and handle both radial and axial loads efficiently. This design enables faster operation compared to open or shielded bearings in similar categories*.

  • 3. Dual-Load Compatibility

    • With radial and axial load capacity, you can deploy this bearing in diverse machinery, from electric motors to industrial equipment, offering versatility unmatched by single-load-focused bearings*.

  • 4. Rubber-Sealed Protection

    • With a black rubber seal (likely NBR), you can minimize dust and moisture ingress, reducing maintenance needs compared to open-seal bearings in dusty or wet environments*.

  • 5. Precision-Engineered Reliability

    • With precision ratings from P0 to P5, you can guarantee consistent performance in precision machinery, surpassing standard-grade bearings in accuracy and longevity*.

  • Notes:

    • The "sealing type: open" in product attributes conflicts with the image's rubber seal description. The seal detail from the image was prioritized for accuracy.
