Detailed Description
Auxiliary Bearing Bush is a vital bearing component in steam turbine auxiliary systems, supporting pumps and fans while minimizing energy loss. With an outer diameter ≤φ500mm, it is made from copper-based alloy or ceramic composite, featuring electroplated surfaces for corrosion resistance, operating from -30°C to 450°C. It excels in shock absorption and load distribution, suitable for biomass power plants and industrial CHP systems.
