Stainless Steel Bearings
Stainless steel bearings are made of 100% stainless steel that provides the bearings resistance to corrosion and prevents it from eroding. This contributes to reduced maintenance and lower costs of replacing bearings during machine operations. Further, the quality of the bearings is good which helps decrease downtime and keep the machine in optimal functioning for longer. Not only do these bearings withstand arduous and corrosive work conditions but also contamination.
Austenitic stainless steel bearings
The primary composition of Austenitic stainless steel bearings is Chromium & Nickel; and these bearings are not magnetic. They are available in AI 304 and AI 316 forms that have mechanical properties.
The Austenitic stainless steel bearings can resist corrosion which makes them ideal for a range of applications. These bearings are used in the pharmaceutical industry, food industry and for machines used in the marine industry.
Duplex stainless steel bearings
A combination of the Ferritic and Austenitic structures make for these duplex stainless steel bearings. Their corrosion resistance is excellent enough to make them withstand stress corrosion cracking and these bearings have a high strength.
Machines that are used in challenging work conditions have duplex stainless steel bearings as they are robust. Mostly, the 2205 grade form of duplex stainless steel bearings are used because of their strength. These bearings serve their purpose in the marine industry and the oil & gas industry because they work well even in harsh environments.
Martensitic steel bearings
Martensitic steel bearings consist of Chromium and a high amount of Carbon content that makes these bearings robust. They resist corrosion moderately but the hardness & strength is high and is treatable under heat.
The 440 C form of Martensitic steel bearings is most commonly used as it has the potential to offer a lot of hardness. These steel bearings find their use in high-load applications and machines that undergo increased wearing. Martensitic steel bearings are used in industrial machinery as well as in the aerospace industry because of their properties.
Ferritic stainless steel bearings
Ferritic stainless steel bearings, which are magnetic, contain a low amount of Carbon content and Chromium. These bearings are not only resistant to corrosion but also to oxides in the environment. However, these bearings are not treatable under heat and their carbon content is lower than that of the Martensitic steel bearings.
Machines in work environments that require bearings with moderate corrosion resistance usually have Ferritic stainless steel bearings. These bearings find their use in the automotive industry and various other appliances that have exposure to the oxidation process.
