How to choose the right motor bearing for the motor?
Motor products are devices that convert electrical energy into mechanical energy. The most critical factor is the selection of motor bearings. The load capacity of the bearing must match the power and torque of the motor, and the size of the bearing must be consistent with the physical space of the motor-related components. The size of the bearing load is usually one of the main determinants of the bearing size. Roller bearings generally have higher load capacity than ball bearings of similar size, and full roller bearings can withstand heavier loads than corresponding bearings with cages. Ball bearings are mostly used for medium or small loads. Under heavy loads and large shaft diameter conditions, roller bearings are relatively safe and reliable.
In many cases, it is necessary to consider multiple factors when selecting a bearing type and weigh the pros and cons of these factors. The important considerations when selecting a standard bearing type mainly include space, load, misalignment, accuracy, speed, noise, stiffness, axial displacement, installation and disassembly, embedded seals, load size and direction, etc.
Various bearing types have unique characteristics due to their design, which make certain types of bearings show a tendency to be applied. For example, deep groove ball bearings can withstand medium radial and axial loads, have low friction, and can provide a variety of different designs such as high precision and low noise, so they are particularly suitable for small and medium-sized motors. Spherical roller bearings can withstand heavy loads and have the characteristics of self-aligning. Therefore, they are suitable for heavy machinery with heavy loads, shaft deflection and misalignment.
