Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High Load Capacity & Speed Performance: Designed to handle heavy radial loads and high rotational speeds, ideal for demanding applications requiring durability and efficiency.
  • Double Row Cylindrical Design: Features a double-row configuration with steel-caged cylindrical rollers, enhancing radial load distribution and stability.

Key features

  • 1. High-Strength Material Technology for Durability

    • With high-strength chrome steel construction and a robust steel cage, this bearing ensures exceptional durability under heavy loads and prolonged use. The steel cage design enhances stability and reduces wear compared to plastic-caged alternatives, making it ideal for demanding industrial applications. ~25% more resistant to deformation than bearings with plastic cages*.

  • 2. Double-Row Design for Multi-Axis Load Handling

    • With a double-row cylindrical configuration and full complement of rollers, this bearing can handle high radial and axial loads while maintaining high rotational speeds. The double-row design supports up to 30% greater axial load capacity than single-row bearings*, enabling reliable performance in machinery like gearboxes and presses.

  • 3. Precision-Engineered Performance

    • With precision ratings from P4 to P2 (ISO tolerance classes), this bearing achieves ultra-precise rotational accuracy, critical for high-precision machinery. The tightest P2 rating ensures up to 50% tighter tolerances than standard P6 bearings*, minimizing vibration and ensuring smooth operation.

  • 4. Industrial-Grade Scenario Adaptability

    • Designed for continuous operation in heavy machinery, this bearing delivers uninterrupted performance in applications like conveyors and industrial equipment. Its open design and chrome steel construction excel in clean environments, outperforming general-purpose bearings in 24/7 operational demands*.

  • 5. Certified Safety and Compliance

    • Complies with CE standards, ensuring safety and quality for industrial use. This certification guarantees adherence to EU safety regulations, exceeding requirements of non-certified alternatives*.

Supplier's note

  1. Three Technical Breakthroughs:

    • Full complement design: Steel-caged rollers provide 20% higher load capacity than standard bearings.
    • Precision range (P4-P6): Enables compatibility with precision machinery across industries.
    • CE certification: Ensures compliance with EU safety standards for global deployment.

  2. Version Selection Guidance:

    • Base Model: Optimal for general industrial use (e.g., conveyors) with P6 precision and 3000 RPM speed.
    • Advanced Model: Ideal for heavy machinery (e.g., presses) needing 15% higher load capacity and P5 precision.
    • Pro Model: Best for high-precision equipment (e.g., CNC machines) with triple the radial load capacity of industry benchmarks and P4 accuracy.

With the Pro model’s P4 precision, you can achieve ultra-accurate positioning in CNC machinery. The Advanced model’s increased load capacity allows reliable operation in high-demand presses. The Base model’s P6 rating is optimal for standard conveyor systems. The Pro model’s 4000 RPM speed outperforms industry standards by 33%, enabling faster machinery cycles.
