[Daily Reading] The demand for rolling bearings used in various mechanical equipment and instruments in shopping malls is becoming increasingly strict. The conditions and functions required for bearings are also becoming more diverse. To select the most suitable bearing from a wide range of options, it's essential to analyze the requirements from multiple perspectives. When selecting bearings, factors such as placement, installation, ease of disassembly, space, size, and shaft alignment should be considered. Additionally, the lifespan of machines using bearings and the different endurance limits of the bearings must be compared to determine the appropriate size. While fatigue life is often the primary concern, other factors like smoothness, wear, and noise caused by aging should also be taken into account. Depending on the application, specific requirements for precision, clearance, cage design, lubrication, and sealing must be met. There are no strict rules or fixed orders when choosing bearings; instead, priority should be given to the actual conditions and functions required. Practical experience plays a crucial role in making the right decision. Key considerations during bearing selection include: - Operating conditions and environmental factors - Dimensions of the bearing housing - Available space - Load size and direction - Vibration and impact levels - Rotational speed and bearing limit speed - Axial alignment of inner and outer rings - Axial fixation and bearing arrangement - Ease of installation and removal - Noise and torque - Rigidity - Cost-effectiveness, layout, and positioning - Machine usage and expected service life - Equivalent dynamic or static load - Rotation speed - Allowable static load factor - Axial load capacity (especially in cylindrical roller bearings) Additional factors to consider: - Rotational accuracy - High-speed performance - Torque variation - Bearing accuracy level - Fit and tolerance - Temperature difference between inner and outer rings - Deflection of the rings - Preload and internal clearance - Noise and operating temperature - Cage design and material - Lubrication method and type - Sealing method and protection - Installation and removal procedures - Tooling and device compatibility Bearing selection is a complex process that requires careful evaluation of both technical and practical aspects. It’s important to understand the specific needs of your application and choose a bearing that not only meets those needs but also ensures long-term reliability and performance.
