Core Keyword: High‑load self‑lubricating bearing bush

For heavy-duty mechanical systems operating under extreme load, friction, and harsh environmental conditions, traditional lubricated bearing bushes often fail prematurely due to insufficient lubrication, wear, corrosion, and frequent maintenance downtime. Our high-load self-lubricating bearing bush is engineered to solve these pain points, delivering stable, long-lasting, and maintenance-free performance for industrial heavy-load scenarios.

Superior High-Load Bearing Capacity for Extreme Working Conditions 

Designed exclusively for heavy-load operation, our self-lubricating bearing bush boasts exceptional mechanical bearing performance. It supportsstatic load up to 250MPa and dynamic load up to 140MPa, perfectly adapting to low-speed heavy-load, intermittent oscillation, and impact load working modes that ordinary bearings cannot withstand. The high-strength steel or bronze alloy substrate effectively resists deformation and edge wear under long-term high-pressure operation, ensuring structural stability even in misaligned shaft and heavy shock load environments.

Integrated Self-Lubricating Design, 100% Oilless Operation

Different from conventional bearing bushes that rely on regular oil refueling, this high-load self-lubricating bearing bush adopts an embedded solid lubricant composite structure. The sintered bronze layer or PTFE friction lining is perfectly combined with the metal substrate, forming a uniform and durable self-lubricating film during operation. It reduces startup friction by up to 80% compared with traditional bronze bearings, eliminates dry friction and component jitter, and realizes zero external lubrication maintenance throughout the service life.

The stable lubricating film also protects matching shafts and seals, extending the service life of supporting accessories by 3–5 times and greatly reducing equipment failure rates caused by poor lubrication.

Excellent Environmental Adaptability & Long Service Life

Our high-load self-lubricating bearing bush breaks through the usage limitations of traditional lubricated bearings and performs stably in extreme environments:

  • Wide temperature resistance: Operates reliably in the temperature range of -40°C to 400°C, covering low-temperature cold storage and high-temperature industrial baking scenarios

  • Strong corrosion resistance: Optional stainless steel backing and anti-corrosion friction layer, resistant to saltwater, chemical fluids, and food-grade cleaning agents, suitable for marine, chemical, and food processing industries

  • Wear & contamination resistance: Resists dust, mud, and humid environment erosion, maintains stable sliding performance in polluted working conditions, and achieves over 2 million stable working cycles

Wide Industrial Application Scenarios

Tailored for heavy-duty industrial equipment, our high-load self-lubricating bearing bush is widely applicable to:

  • Engineering machinery: Excavator joint parts, large gearboxes, hydraulic cylinder guide parts

  • Heavy industry equipment: Rolling mills, turbine equipment, dam gate hinges

  • Marine & chemical equipment: Marine hydraulic systems, chemical processing transmission parts

  • Automation & precision machinery: Low-speed heavy-duty automation equipment, valve transmission components
