The choice of cast iron or cast steel bearing housing depends on the specific application requirements and working environment.

Cast Iron Bearing Housing:
Advantages: lower cost, higher hardness, easy to cast molding and processing.
Disadvantages: poor toughness, wear resistance, corrosion resistance is not as good as cast steel.
Application: cast iron bearing housing is suitable for low speed, light load and high precision operation is not required.

Cast Steel Bearing Housing:
Advantages: high hardness, high strength, good wear resistance and corrosion resistance, stable chemical composition and good processing performance.
Disadvantage: the weight is larger and the cost is higher.
Application: cast steel bearing housing is mainly used for large and high load mechanical equipment
