We are manufacturing and supplying sintered bushes parts with the
following technical specifications:
With the obviously advantages, It is widely used in domestic
electric appliance, electric tools, textiles machinery, chemical
machinery and automobile industry, etc.
Sintered porous metal bearings are powder metallurgical parts, the
starting materials are obviously metal powder. The metal powder
used are specifically produced to give flow and compacting
characteristic and at the same time ensure best mechanical
strength, grade or porosity for oil retention and self-lubrication
in its finished form.
Sequence of Production:
• Forming (or compacting)
• Sintering
• Sizing
• Oil Impregnation
Range:
• Plain & flanged bushes, self-aligned bushes, solid rod, plate,
sintered bushes, oilite bushes, self-lubricated bushes, sintered
bearings and different profile components as per drawings /
samples.
Applications:
• Sintered bronze bushes are used for high speed application ( up
to 18000 rpm)
• Iron Sintered bushes are used for speed (up to 3000 rpm)
