steel outside and Babbitt metal inside-for bearing

The outer ring is made of steel, and the inner ring is made of Babbitt alloy. This design combines the advantages of steel and Babbitt alloy to provide excellent performance and durability.

Babbitt alloy is a high-strength and high-hardness alloy material known for its outstanding wear resistance and corrosion resistance. It is typically composed of metals such as chromium, nickel, and cobalt, and undergoes special heat treatment processes to enhance its strength and hardness. This enables the inner ring to withstand high loads and stresses under high-speed operating conditions.

The outer ring of the outer steel inner Babbitt alloy bearing is usually made of high-quality steel, which possesses good strength and toughness to withstand external loads and impacts. Additionally, steel offers excellent dimensional stability and heat conductivity.

Due to the combination of steel and Babbitt alloy characteristics, outer steel inner Babbitt alloy bearings exhibit superior wear resistance, corrosion resistance, and high-temperature resistance. This makes them well-suited for applications with high loads and high speeds, such as mechanical equipment, automotive engines, and aerospace engines.

However, selecting the right bearing design requires considering multiple factors, including application requirements, load types, operating conditions, and environment. It is advisable to consult with professional engineers or bearing manufacturers when choosing bearings to ensure optimal selection and performance.
