Introduction

Bearings are critical components in machinery across industries, enabling smooth rotation and reducing friction. For international buyers, selecting the right bearing type directly impacts operational efficiency and supply chain reliability. However, challenges like inconsistent quality, unclear compliance standards, and supplier verification complexities often delay procurement decisions.

1. Bearing Definitions & Technical Specifications

Bearings are mechanical elements that constrain relative motion to rotation. Key types include:

• Ball Bearings: Handle radial/thrust loads via rolling elements (ISO 15:2011)
• Roller Bearings: Cylindrical/tapered rollers for heavy loads (ISO 355:2007)
• Thrust Bearings: Axial load specialists (ABMA Std 22.2)
