Turned Parts and Bearings made from Bronze or Brass
Machined cast bronze bearings offer technically and economically
favorable bearings solutions. It is with high load capability, low
weight and good corrosion resistance. We can offer different types
of bronze alloys according to the required life time, service etc.
The tolerance is much tighter than e.g. wrapped bronze bushes.
All these bearings are made to order. Other shapes can be offered.
Graphite loaded bearings can withstand very high temperatures up to
425°C (800°F) as well as cryogenic temperatures down to -200°C
(-400°F) depending on the bronze material and graphite selected.
Bronze Bearings are widely used in many industrial areas. Such as ,
machine tools, molds, agriculture and forestry water machinery,
etc.
