SS 6004 ZZ/2RS stainless steel deep groove ball bearings

The SS 6004 (20×42×12 mm) is a model in the 6000 series specifically designed for "high load and large shaft diameter" applications. With an increased inner diameter of 20mm, this bearing significantly enhances radial load capacity and structural rigidity while maintaining the excellent corrosion resistance of stainless steel. Utilizing high-strength 3Cr13 (AISI420) and 9Cr18Mo (AISI440C) stainless steel combined with advanced strengthening heat treatment processes, the SS 6004 can easily handle the continuous operation requirements of heavy machinery in harsh conditions such as humid and corrosive environments.

  • Due to its superior load-bearing properties, SS 6004 is widely used in the following heavy-duty anti-corrosion applications:

    Heavy-duty water pumps and submersible pumps: Supporting larger diameter shafts and providing long-lasting power in water-exposed environments.

    Agricultural machinery and garden equipment: High-load transmission systems exposed to outdoor rain and soil environments.

    Industrial washing and dyeing equipment: Withstanding high temperatures, high humidity, and frequent washing with chemical detergents.

    Automated conveyor spindles: Drive rollers and heavy-duty conveyor belt supports in large logistics sorting systems.

    Outdoor sports and power systems: Medium-sized electric vehicle bearings and high-end all-terrain vehicle transmission components.

  • Enhanced Load Support: Compared to smaller models, the SS 6004 features larger balls and thicker inner and outer ring walls, giving it superior impact resistance and structural stability during high-speed operation.

    Industrial-Grade Fully Sealed System: 2RS Rubber Seal: Optimized for heavy-duty pump applications, the double-lip contact design ensures that internal grease remains uncontaminated even in high-pressure washing or muddy environments.
    ZZ Metal Dust Cover: Suitable for heavy-duty automated equipment requiring high speed and low friction.

    High-Precision G10 Grade Steel Balls: Internally equipped with G10 grade high-roundness steel balls, effectively dispersing contact stress, improving rotational accuracy, and significantly reducing temperature rise under heavy loads.

    Excellent Chemical Resistance: The surface undergoes professional passivation treatment, maintaining the integrity of the metal surface and preventing premature peeling even with prolonged contact with moisture, cleaning agents, or weakly corrosive media.

  • Every set of Aosen SS 6004 bearings strictly adheres to ISO international standards. For our B2B customers with specific requirements, we can provide salt spray test reports and hardness test certificates. Whether you need the extremely low friction ZZ type or the highly sealed 2RS type, we can offer you cost-effective wholesale solutions.
