An oilless bushing, also known as an oil-free bushing or bearing, is a type of plain bearing designed to function without the need for lubrication. Unlike traditional bearings that require oil or grease for smooth operation, oilless bushings contain materials with inherent lubrication properties, enabling them to support rotating shafts in industrial machines efficiently.
Oilless bushings are essential in various applications where lubrication is impractical or undesirable, including:
They offer significant benefits such as reduced maintenance costs and simplified machinery design by eliminating the need for lubrication systems.
Oilless bushings achieve lubrication-free operation through:
Incorporating solid lubricants like molybdenum disulfide or metallic saponite into the bushing material, reducing friction.
Using engineering plastics with low friction coefficients, such as Teflon (PTFE), polyacetal, and PEEK, which offer excellent balance in strength and safety.
Oilless bushings are categorized by their material composition into:
Made from materials like polyacetal and tetrafluoroethylene, these bushings are lightweight, low-cost, and have a low coefficient of friction.
These bushings feature a back metal and a surface layer of resin or solid lubricant, offering a compact design and excellent mechanical strength.
Constructed from copper or aluminum alloys embedded with solid lubricants like graphite, suitable for high-load applications and offering a long life.
The lifespan of an oilless bushing is determined by wear and tear from use. Theoretical formulas calculate the wear rate, considering factors like specific wear rate, design surface pressure, operating speed, and friction time. Proper design ensures that the bushing meets its required lifespan without exceeding the designed wear volume, thereby maintaining operational efficiency and reliability.
