Non-Standard Bearing with Stepped Bore

The core feature of non-standard bearings with stepped bores is their stepped inner bore (including two or more coaxial bore sections of varying diameters). This allows for precise positioning of shaft segments with varying diameters, eliminating the need for additional positioning components. It also distributes loads and reduces stress concentration. Customizable features include adjusting the number of steps and diameter based on shaft parameters; selecting the bearing structure (e.g., deep groove ball, cylindrical roller), material (e.g., bearing steel, stainless steel), and seal configuration based on operating conditions to accommodate high and low temperatures, dust, and other environments.

This type of bearing is commonly used in general machinery (reducers, transmission shafts) and automotive applications (steering shafts, axles), simplifying assembly, minimizing errors, and improving stability under vibration. Adaptation requires determining the bearing solution based on shafting parameters (e.g., number of steps, shaft diameter tolerance) and environmental conditions. The production process includes custom design, mold development, precision machining, and performance testing (e.g., bore coaxiality and rotational accuracy testing) to meet specific equipment requirements.
