Introduction of plain bushing
A plain bearing is the simplest type of bearing, comprising just a bearing surface and no rolling elements. Therefore the journal (i.e., the part of the shaft in contact with the bearing) slides over the bearing surface. The simplest example of a plain bearing is a shaft rotating in a hole. A simple linear bearing can be a pair of flat surfaces designed to allow motion; e.g., a drawer and the slides it rests on or the ways on the bed of a lathe.
Plain bearings, in general, are the least expensive type of bearing. They are also compact and lightweight, and they have a high load-carrying capacity.

 

Introduction of SF-1(DU) PTFE composit bushing

SF-1 is wall wrapped bushing made of triple layer composites material which be consisted of a steel backing a sintered prrous bronze particles interlayer and calendared with PTFE and Pb mixture as surface layer. It is of low friction coefficient, anti-wear , anti-corrosion and can be used without oil, or only a trace of oil if needed. Moreover, it is of low cost, low vibration and low noise, compacted and light, SF-1 is widely applied in various sliding articles of different kind of machines, such as textile machines, tobacco machinese, hydraulic vechicles, automobiles, agriculture and forests machinese and so on.
