A porous bearing is a self-lubricating component made from powdered metal, typically bronze or iron, sintered to create interconnected oil-filled pores. This structure provides continuous lubrication without external oiling, reducing maintenance and extending service life. Ideal for fractional-horsepower motors, fans, power tools, and automotive accessories, porous bearings offer quiet operation, high wear resistance, and cost-effectiveness. They operate efficiently across moderate speeds and loads. Once installed, the bearing’s internal oil supply is released through capillary action during rotation or heating, ensuring consistent film strength and low friction.
Porous structure retains lubricating oil for continuous, maintenance-free operation and reduced friction.
Sintered metal construction delivers high load capacity and long service life in automotive and industrial applications.
Eliminates need for regular lubrication, lowering maintenance costs and ensuring consistent performance.
