Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Precision Rotation: Designed with a deep groove structure and ABEC-1 precision rating, enabling smooth, low-friction operation for precise mechanical movements.
  • Load Handling: Stainless steel construction and steel cage ensure robust support for axial and radial loads in demanding applications like guide tracks and machinery components.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a stainless steel construction and bearing steel components, ensure durability in harsh environments such as marine applications or high-humidity settings. ~30% more corrosion-resistant than plastic-caged alternatives*.

  • 2. Precision-Engineered Interactive Design

    • With the U-shaped groove and deep groove structure, achieve smooth rotation and precise alignment in guide track systems, reducing operational friction by up to 25%* compared to standard bearings.

  • 3. High-Performance Parameters

    • With ABEC-1 precision rating and a 17mm thickness, deliver exceptional rotational accuracy and load capacity, reducing vibration by 15%* versus non-ABEC bearings. Dual sealing options (ZZ/2RS) further extend service life by protecting against contaminants.

  • 4. Versatile Scenario Solutions

    • Designed for guide track systems in industrial machinery, automotive parts, and conveyor equipment, enabling continuous operation in demanding environments like automotive assembly lines or heavy-duty manufacturing.

  • 5. Certified Precision Standards

    • Certified to ABEC-1 precision standards, ensuring consistent performance and compatibility with high-precision mechanical applications across industries.

Supplier's note

  1. Technical Breakthroughs:

    • ABEC-1 Precision: Enables high rotational accuracy for CNC machinery and robotics.
    • Dual Sealing Options: ZZ shields protect against dust in factories, while 2RS seals guard against lubricant leaks in wet environments.
    • Hybrid Material Design: Combines bearing steel’s strength with plastic’s lightweight properties for reduced energy consumption.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial equipment (e.g., conveyor belts) requiring cost-effective solutions.
    • Advanced Model: Preferred for food processing or chemical plants needing chemical resistance and wider temperature tolerance.
    • Pro Model: Tailored for heavy-duty robotics or aerospace applications where extreme loads and high speeds are critical.

With the Pro Model’s 6,500 N load capacity (30% above industry standards), users can safely handle heavy machinery without compromising rotational efficiency. Pair its PTFE-lined seals with the metal cage to ensure zero corrosion in marine settings, extending service life by 40%.
