SF-2(DX) MARGINALLY LUBRICATED BEARINGS

Structure 1.POM 0.30 0.50mm,has high wear resistance and low friction even only minute quantities of lubricant are supplied,this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing. 2.Sintered bronze power 0.20 0.35mm,provides max.thermal conductivity away from the bearing surface, also serves as areservoir for the resin mixture. 3.Low-carbon steel,gives exceptiongally high load carrying capacity,excellent heat dissipation. 4.Copper plating 0.002mm,good corrosion resistance.
