Low-cost oil-impregnated bearings to replace bronze oil-impregnated bearings.
"Polite BCF" is an oil-embedded bearing that uniformly disperses iron components and bronze alloy components, providing a familiarity similar to copper-based bearings due to the bronze alloy components, while imparting wear resistance through the base effect of the iron components. By bringing out the characteristics of each component, it enables use in various applications. By incorporating iron components into the material, the raw material costs can be significantly reduced compared to copper-based bearings, allowing for the provision of low-cost oil-embedded bearings. 【Features】 ■ Has familiarity equivalent to bronze-based bearings ■ Wear resistance is comparable to iron-based bearings and significantly superior to bronze-based bearings ■ Lower cost compared to bronze-based bearings ■ Excellent load-bearing capacity, making it suitable for use at high PV values ■ Compliant with ELV and RoHS *For more details, please download the PDF or contact us.
