Achieved reduction in raw material costs! Awarded the Encouragement Prize (New Product Award, Material Division) at the 29th Japan Powder Metallurgy Association Awards.
"Polite ASO" is a material for oil-containing bearings that achieves a reduction in raw material costs while maintaining bearing performance equivalent to traditional iron-copper-based materials. By controlling the content of hard impurities (such as SiO2 and Al2O3) present in the iron powder raw material, it prevents attacks on the shaft material and improves reliability. 【Features】 ■ Superior corrosion resistance compared to iron-based materials and traditional iron-copper-based materials (BCF materials) ■ Reduced permeability compared to traditional iron-copper-based materials ■ Compliant with ELV and RoHS *For more details, please download the PDF or contact us.
