The SF-1B bronze bearing is engineered for high-load, low-friction applications, featuring a durable bronze matrix embedded with solid lubricants for maintenance-free, long-lasting performance. Ideal for industrial machinery, agricultural equipment, and heavy-duty transmission systems in high-temperature, high-pressure environments, it significantly reduces wear and energy consumption.
Key Advantages
1. Exceptional Load Capacity
The bronze alloy + steel-backed structure withstands over 30MPa dynamic load, offering 3x longer lifespan than standard bearings—perfect for heavy-duty machinery bearings.
2. Ultra-Low Friction Design
Pre-embedded graphite/PTFE lubricants achieve a friction coefficient of 0.04–0.08, minimizing startup torque for low-speed high-load bearing applications.
3. Self-Lubricating, Zero Maintenance
Patented solid-lubricant technology eliminates grease contamination, ideal for food-grade lubricant bearings or dusty environments.
4. High-Temperature & Corrosion Resistant
Operates in -200°C to +300°C ranges with anti-corrosion properties, meeting high-temperature high-pressure bearing demands.
5. Custom Solutions
Tailored sizes available, including wear-resistant bronze bushings for specialized equipment.
