Powder Metal Bushes
HMEC® powder metal bushes are made of bronze or iron powder, mold pressed in high pressure, sintered in high temperature and soaked in oil by vacuum.It's used in electric appliances, electric tools, textiles machinery, chemical machinery and automobile industry, etc.
DU/DX Metal-Polyer Bushes
HMEC® DU/DX metal-polyer bushes are made of triple layer composites material which be consisted of a steel backing, a sintered porous bronze particles interlayer and calendared with PTFE and 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 machines, hydraulic vehicles, automotives, agriculture and forest machines and soon.

HMEC® bi-metal bushes are made of high quality low-carbon steel, sintered copper alloy of CuPbSn10 or CuSn8P or CuPb30 , the alloy surface is curved with oil groove or rolled to diamond oil grooves. It has good lubricating and corrosion resistance property, it can work in the condition of little of oil or none of oil. It is particularly applied to high temperature, water solution and the occasions where cannot be added oil.
