Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Reduces Friction & Supports Loads: Designed to minimize friction and handle radial/axial loads in rotating applications, enabling smooth operation in machinery and equipment.
  • Durable Construction: Steel cage and grease lubrication ensure reliable performance under continuous operation, while bearing steel material guarantees high load-bearing capacity.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With corrosion-resistant bearing steel and dual rubber (2RS) seals, ensure durability and protection against contaminants and moisture. ~20% longer lifespan than standard sealed bearings*

  • 2. Comprehensive Certification Standards

    • With certifications including REACH, RoHS, CE, and IEC62321, meet stringent global environmental and safety regulations for industrial and consumer applications.

  • 3. Precision Performance Parameters

    • With ABEC-1 precision rating, achieve high rotational accuracy and smooth operation in precision machinery, outperforming lower-grade bearings in alignment and speed consistency.

  • 4. Enhanced Structural Integrity

    • With a steel cage, distribute loads evenly and withstand heavy-duty use, offering superior strength compared to plastic-caged bearings*.

  • 5. Versatile Scenario Solutions

    • Designed for compact applications, integrate seamlessly into space-constrained equipment like consumer electronics, automotive components, and machinery. Dual-seal design and grease lubrication enable reliable performance in harsh environments.

Supplier's note

  1. Technical Breakthroughs:

    • ABEC-1 Precision: Achieves smoother operation in precision machinery compared to non-graded bearings.
    • 2RS Seals: Offer 30% better dust resistance than standard rubber seals, extending lifespan in harsh environments.
    • Bearing Steel Composition: 20% higher fatigue resistance than generic steel, ensuring longevity under cyclic loads.

  2. Version Selection Guidance:

    • Base Model: Suitable for general industrial equipment (e.g., small pumps) where standard load and speed suffice.
    • Advanced Model: Ideal for automotive or robotics applications needing higher thermal and speed tolerance.
    • Pro Model: Designed for heavy machinery or extreme environments (e.g., mining equipment) requiring robust load handling and temperature resilience.

With the Pro Model’s 30 kN load capacity, you can safely integrate it into heavy-duty systems where traditional bearings fail. Pair its heat-resistant lubrication with the 2RS seal to maintain performance in high-temperature factories.
