Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High Radial Load Support: The double-row cylindrical design and high-grade steel construction (stainless steel/chrome steel) enable robust handling of heavy radial loads in dynamic applications.
  • High-Speed Performance: Optimized for high rotational speeds with minimal heat generation, ideal for machinery requiring rapid, sustained operation.

Key features

  • 1. Material Technology: Corrosion-Resistant Stainless Steel & Chrome Steel Construction

    • With a stainless steel and chrome steel composition, you can ensure exceptional durability and corrosion resistance in harsh industrial environments. The brass and steel cage further enhances structural integrity, supporting prolonged use under heavy loads.

  • 2. Structural Design: Double Row & Full Complement Configuration

    • With a double row cylindrical design and full complement rollers (no cage), you can achieve 25% higher radial load capacity compared to single-row bearings, while maintaining smooth high-speed operation. This design minimizes friction and optimizes load distribution for demanding machinery.

  • 3. Precision Engineering: High-Precision P4-P6 Ratings

    • With precision ratings from P4 to P6, you can guarantee ultra-accurate alignment and minimal rotational play, ensuring reliability in precision machinery such as industrial equipment and high-speed motors.

  • 4. Scenario Solutions: Heavy-Duty Industrial Applications

    • Designed for high-radial-load environments, this bearing is ideal for heavy machinery, large vehicles, and continuous industrial use. Its open sealing allows customization of lubrication for specific operational conditions, such as high-temperature or dry environments.

  • 5. Customization & Adaptability: Modular Options for Versatility

    • With customizable precision levels (P0-P6), lubrication types, and sealing options, you can tailor the bearing to fit diverse applications—from high-speed robotics to heavy-duty construction equipment.
