Analysis of porous metal bearings<\/h2>\n

1. What are porous metal bearings?<\/h3>\n

Porous metal bearings are bearings made of porous metal materials. They store lubricants through their unique pore structure, thereby achieving long-term self-lubricating effects. They are mainly made of metal powders such as bronze and iron-based alloys, and are processed and formed by powder metallurgy technology. They are widely used in low-speed and medium-load conditions, especially in occasions where frequent maintenance is difficult.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n
