Which material is stronger and suitable for light to heavy loads in bearing housings?

Cast steel is recognized for its strength, durability, and ability to handle significant loads, making it an ideal choice for bearing housings that are subjected to both light and heavy loads. The material's high tensile strength and fatigue resistance are particularly beneficial in high-stress applications that require reliable performance over time.

In contrast, while cast iron is strong, it can be brittle and less suitable for dynamic loading situations where impact and shock loading may occur. Aluminum alloys, although lightweight and resistant to corrosion, typically do not possess the same strength characteristics as cast steel, rendering them less effective for heavy load applications. Carbon fiber provides incredible strength-to-weight properties, but its use in bearing housings is limited due to its cost and the need for careful design to handle loads effectively. Therefore, cast steel stands out as the most appropriate material for bearing housings across a range of load conditions.
