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.
