Carbon Graphite Brass Bearing JDB Bushing SL4 Copper Sleeves for Washing Machine Gearboxes

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Friction Reduction & Load Support: Designed to minimize friction and support rotational motion in machinery, featuring a bronze-copper-brass composite with embedded graphite for enhanced lubrication and wear resistance.
  • Weight Optimization & Cooling: Hollow cylindrical design with evenly spaced holes reduces weight while improving heat dissipation, ideal for high-speed or continuous-use applications.

Key features

  • 1. Material Technology: Copper-Brass Composite with Graphite Lubrication

    • With a corrosion-resistant copper-brass alloy infused with graphite, reduce friction and wear in high-load applications. The graphite lubrication ensures smooth operation without frequent maintenance, outperforming traditional brass bushings by up to 30% in wear resistance*.

  • 2. Interactive Design: Sleeve-Type Construction for Precision Fit

    • The sleeve design provides a seamless, polished finish for tight tolerances in washing machine gearboxes. Its cylindrical geometry ensures precise alignment, minimizing vibration and noise compared to non-sleeve bushings*.

  • 3. Performance Parameters: High-Speed Load Capacity

    • Engineered to handle continuous rotational speeds of up to 3,000 RPM, this bushing maintains stability under heavy loads, exceeding the durability of standard bronze bushings in domestic appliances*.

  • 4. Scenario Solutions: Optimized for Domestic and Commercial Gearbox Use

    • Designed for frequent start-stop cycles in washing machines, the carbon-lubricated surface prevents seizing, ensuring reliable operation in both residential and commercial settings where maintenance intervals are critical*.

  • 5. Certification Standards: SVHC Compliance for Safe Use

    • Certified under the SVHC (Substances of Very High Concern) regulation, this bushing meets strict environmental and safety standards, avoiding restricted hazardous materials—ideal for eco-conscious manufacturers*.

Supplier's note

  1. Three Technical Breakthroughs:

    • Material Blend: The copper-brass-graphite alloy provides 40% better wear resistance than standard bronze bushings.
    • Carbon Lubrication: With impregnated graphite, friction reduction improves by 25% compared to dry-running bushings.
    • Hole Design: Strategically placed holes reduce weight by 20% while maintaining structural integrity.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard residential washing machines where moderate load and temperature are key.
    • Advanced Model: Suitable for commercial laundry systems requiring enhanced durability and reduced maintenance.
    • Pro Model: Designed for industrial gearboxes operating at high loads (e.g., heavy-duty washing machines) and elevated temperatures. With its ultra-low friction coefficient, it extends lifespan by 30% in abrasive environments.

*Pro Model load capacity exceeds industry benchmarks by 25%.
