Linear bearing production technology

Careful selection of materials: The first step in the production of linear bearings with a solid foundation focuses on the fine selection of materials. The use of high-quality cold-drawn steel, hot-rolled or cold-rolled steel strips ensures that the carbon content of the material is maintained in the ideal range of 0.15% to 0.25% to meet the needs of different sizes of bearings. In addition, the precise control of material hardness is the key, too soft or too hard is not conducive to the long-term performance of the bearing.
Second, cold extrusion technology: the art of shape shaping The next process is cold extrusion molding, which requires precise cutting of the material to the appropriate length, followed by pickling and cleaning, cold heading operation, until the formation of the basic shape of the linear bearing. The core of this stage is to closely monitor the quality of the material to ensure that the processing process does not compromise its inherent properties.
Third, heat treatment: strengthen the internal quality after cold extrusion forming, the heat treatment process is immediately launched to optimize the microstructure of steel and improve its comprehensive mechanical properties. The process includes tempering and quenching technology, the former is suitable for high carbon steel, balance hardness and toughness; The latter is for low carbon steel, designed to enhance hardness, the two complement each other, together to create a solid "bone" for the bearing.
Fourth, precision repair: the details determine the perfect heat treatment of bearings also need to go through a series of precision processing, such as turning, grinding and tooth surface treatment, each link has strict requirements for accuracy, to ensure the high precision and perfect roundness of the bearing. This stage not only tests the accuracy of high-end equipment, but also greatly relies on the superb skills of technical personnel.
Fifth, precision assembly: the overall precision machining of the construction function is completed, and the assembly stage is entered. Using a variety of professional tools such as lockers, hammers and test plugs, each bearing is carefully assembled in accordance with strict procedures and specifications to ensure its complete function and stability.
The production process of linear bearings is a precise journey integrating high-tech equipment and superb manual skills, each step is directly related to the final quality and service life of the product. This is not only a technology, but also an art of the ultimate pursuit of details, reflecting the profound heritage and unremitting pursuit of modern manufacturing.
