how do bearings work in rotating machinery

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)
