Material of Steel Bearing

Chrome Steel

Chrome steel is the most common material for steel bearings due to its excellent combination of hardness, wear resistance, and corrosion resistance. It's suitable for a wide range of applications, from light-duty to heavy-duty.

Stainless Steel

Stainless steel bearings are corrosion-resistant and ideal for applications where exposure to moisture or harsh chemicals is a concern. They are commonly used in the food industry, medical equipment, and marine applications.

Hybrid Ceramic Ball Bearing

Hybrid ceramic bearings are assembled from a ring made of bearing steel and a bearing grade silicon nitride roller (Si3N4), and are used in machine tools, wind turbines, railways and electric vehicle traction motors.

FAQ

 

Q: Is bearing steel strong?

A: Bearing steels are designed for high wear resistance, fatigue strength, and toughness, making them ideal for applications in various industries, including automotive, aerospace, and heavy machinery.

Q: Will bearing steel rust?

A: Steel ball bearings can rust. Bearings made of chrome steel will rust easily which is why they leave the factory with the outer surfaces coated with a protective oil. Stainless steel bearings are much more corrosion resistant but will still rust when coming into contact with certain substances.

Q: What is the most durable bearing?

A: Better bearings are made of real bearing-steel, such as chrome, titanium or Swiss steel. In ceramic bearings (usually used for speed skating) the balls are made of industrial ceramic (Silicon Nitride). Ceramic balls seldom rust and are more durable than steel.

Q: Is bearing steel the same as stainless steel?

A: Carbon steel (or high carbon chrome steel) is the most commonly used material for bearings. It has slightly better low noise characteristics than stainless steel. In addition, its hardness means it has better load capacity than stainless steel bearings.

Q: Is bearing steel harder than stainless steel?

A: Bearing steel is much harder than stainless steel, making it ideal for applications where high wear resistance is required.
