Feb 27, 2025What is a bearing retainer? What materials are bearing retainers made of?
The bearing retainer, also known as the cage, is a key component of a bearing. Its function is to enclose and isolate the rolling elements, allowing them to follow their movement and often guiding them. The cage must withstand stresses caused by friction, strain, and inertia, as well as chemical corrosion from lubricants, lubricant additives, substances generated by lubricant aging, organic solvents, and coolants. Therefore, the cage's design and material are crucial to its performance and bearing reliability.
