Sintered Bronze Sleeve Bearings
Sintered bronze sleeve bearings are self-lubricating bearings made through powder metallurgy technology, which have characteristics such as maintenance free, high temperature resistance, and high load, and are widely used in fields such as automobiles, machinery, and rail transit.
- Product Introduction
Core Features and Working Principles
• Self lubrication mechanism: Powder metallurgy sintering process is used to form a porous structure (porosity of about 30%), which can be filled with lubricating oil or molybdenum disulfide. During operation, the lubricant is slowly released to form an oil film, avoiding direct contact between metals .
• Key advantages: Maintenance free design reduces costs, high temperature resistance (-50 ℃ to 300 ℃), corrosion resistance, and adaptability to high load scenarios .
