A ball bearing is a critical component in modern vehicles, enabling smooth rotation of moving parts while managing both radial and axial loads. In automotive applications, ball bearings are most commonly associated with wheel hubs, but they also appear in engines, transmissions, and suspension systems. Understanding how ball bearings function, […]

Anti-friction bearings are fundamental components in rotating machinery, from automotive wheels to industrial gearboxes. Unlike plain bearings that rely on sliding contact, anti-friction bearings use rolling elements to dramatically reduce friction and energy loss. This guide provides a technical overview of what anti-friction bearings are, how they compare to plain

Sintered bearings, also known as powder metallurgy bearings or oil-impregnated bearings, are a class of porous metal components that contain lubricating oil within their internal pore structure. Unlike conventional rolling element bearings that require external grease or oil supply, sintered bearings are designed to release oil gradually during operation, providing

With over 20 years of manufacturing experience and 15 years in global trade, DUHUI Bearing has witnessed firsthand the critical role that seemingly small components play in massive machinery.
