Introduction

Engine bearings serve as critical components in global machinery trade, enabling smooth rotational motion while reducing energy loss. International buyers face challenges in identifying suppliers who balance ISO-compliant manufacturing with cost-effective solutions, particularly when managing cross-border logistics and quality verification.

The Engineering Behind Engine Bearings

Definition & Technical Specifications

Bearings function as friction-reducing interfaces between engine shafts and housing. Key specifications include:

• Material composition: Babbitt metal (Sn-based) vs aluminum alloys
• Clearance range: 0.025-0.075 mm (passenger vehicles)
• Load capacity: Up to 300 MPa (heavy-duty engines)
