How Do Bearings Work in Rotating Machinery: Complete Guide for Buyers
Introduction
Bearings reduce rotational friction by 80-95% in industrial equipment, making them critical for global machinery exports. International buyers face challenges identifying compliant components that meet ISO/ABMA standards while managing supply chain risks.
Technical Specifications & Standards
- Core function: Enable rotational motion through rolling elements
- Key standards: ISO 15 (radial), ISO 104 (thrust), ABMA 9-1990
- Load capacities: 10kN (ball) to 500kN (roller)
Bearing Type Comparison
Type | Speed | Load | Cost |
---|---|---|---|
Ball | High | Medium | $$ |
Roller | Medium | High | $$$ |
Procurement Advantages
- Cost: 18% lower TCO vs. plain bearings (McKinsey 2023)
- Efficiency: 92% energy retention in modern designs
- Compliance: CE/ISO-certified options available
