1. Types of Steel Ball Bearings
1.1 Stainless Steel Ball Bearings
Stainless steel bearings, such as 316 stainless steel ball bearings and 440C stainless steel ball bearings, are renowned for their corrosion resistance. Ideal for marine environments, food processing equipment, or outdoor machinery, these bearings withstand moisture and chemicals. For example, our 3mm stainless steel ball bearings are popular in robotics and medical devices due to their precision and hygiene.
1.2 Carbon Steel Ball Bearings
Carbon steel bearings, like 52100 ball bearing steel, offer exceptional hardness and load capacity. They’re commonly used in automotive systems, conveyor belts, and heavy machinery. Pair them with proper lubrication to prevent rust in humid conditions.
1.3 Chrome Steel Ball Bearings
Chrome steel bearings combine durability with affordability. The chrome steel ball bearings in our catalog are heat-treated for enhanced strength, making them perfect for high-speed applications like electric motors or power tools.
1.4 Specialty Bearings
