As a key basic component in mechanical equipment, bearings have a close and important relationship between their materials and performance.

Different bearing materials determine their varying hardness performance. For example, bearings made of high carbon steel have high hardness and can withstand large pressures well. They are not easily deformed under heavy mechanical conditions, ensuring the stability of the bearings during operation. And bearings made of copper alloy materials, although not as hard as high carbon steel, have excellent self-lubricating properties, which can effectively reduce the friction coefficient and wear between components, especially suitable for equipment that is difficult to lubricate frequently. The corrosion resistance of materials is also related to the performance of bearings. Stainless steel bearing materials can resist corrosion in humid or corrosive environments, maintain their structural integrity, and ensure long-term reliable operation of equipment; If bearings are made of ordinary carbon steel materials, they are prone to rusting in such harsh environments, which in turn affects their rotational flexibility and service life.

In addition, the toughness of the material is also crucial. Bearing materials with good toughness can better buffer external forces when facing impact loads, avoid damage such as cracks, and ensure that the bearing continues to perform its supporting and rotating functions stably. Therefore, the reasonable selection of bearing materials plays a decisive role in achieving its ideal performance.
