Stainless steel bearings use stainless steel as their core material and achieve non-contact friction and high-precision rotation through a special process. They possess characteristics such as corrosion resistance, high temperature resistance, and low maintenance costs. Their working principle is based on rolling friction replacing sliding friction. A tiny gap is formed between the inner and outer rings and the rolling elements. Lubricant reduces frictional resistance, allowing the rolling elements to roll smoothly within the raceway, achieving efficient rotation. The bearing rings and rolling elements are often made of martensitic stainless steel after vacuum quenching and tempering, while the cage and seal ring skeleton are made of austenitic stainless steel to ensure mechanical strength and load capacity.

The main characteristics of stainless steel bearings include excellent corrosion resistance, resistance to rust, and long-term use in harsh environments such as humid and acidic/alkaline conditions; outstanding high-temperature resistance, maintaining structural stability and mechanical strength over a wide temperature range; low-noise operation, achieved through precision machining and optimized design to reduce vibration and noise; low maintenance costs, with some models using lifetime lubrication, eliminating the need for frequent lubricant changes; and good hygiene performance, with a smooth and easy-to-clean surface, making them suitable for industries with high hygiene requirements, such as food and medical industries. Furthermore, stainless steel bearings are washable and can operate in liquids, further expanding their application scenarios.

In practical applications, stainless steel bearings are widely used in food processing, medical devices, chemicals, aerospace, and other fields. The synergistic effect of their working principle and characteristics makes them indispensable key components in special environments, providing reliable assurance for the stable operation of equipment.
