Kolbenschmidt Pierburg Group KS S800 – KS S803 Lead-free Steel/Bronze Composite for Bushes and Thrust Wash

Brief description of the sliding material 50 µm KS S800 and KS S803 are tribological materials for bushes and thrust washers. This steel/bronze materials excels by high load capacity, good resistance to wear and high adaptability. Its corrosion resistance (e.g. to hot, additiveenhanced oil) is likewise highly. The materials is lead-free and complies with the requirements of the EU Directive on End-of-Life-Vehicles, 2000/53/ EC. Running surface layer CuSn10Bi8Zn3 Bearing structure The plain bearing composite material consists of a steel back and a tin-bismuth-bronze layer sintered on as bearing...

Chemical composition of the the bronze layer Sn others combined Comparison of specific load capacity 200 Spec. load capacity [MPa] The alloying components Sn, Bi and Zn are accountable for the fair material balance of the bearing surface layer. Tin (Sn) increases strength. Bismuth (Bi) improves the emergency run properties and zinc (Zn) enhances the resistance to corrosion. Bushes and thrust washers made of KS S800 have to be supplied with sufficient lubricant in order to keep the wearing rate at its minimum. Production of the sliding material A tin-bismuth-bronze alloy is sintered onto a steel...
