Rolling bearings generally consist of an outer ring, an inner ring, rolling elements, and a cage. The outer ring is installed inside the bearing housing bore and generally does not rotate. The inner ring is mounted on the journal and rotates with the shaft. Rolling elements are the core components of rolling bearings, and the cage evenly separates the rolling elements to prevent friction. Lubricant is also considered the fifth major component of rolling bearings, and it mainly plays the roles of lubrication, cooling, and cleaning. Servo motors have higher requirements for bearings due to their operating characteristics. At the same time, servo motors for different applications have more detailed requirements for bearings. For standard servo motors, deep groove ball bearings with seals or dust covers are often used. Cylindrical roller bearings are used only in medium and large motors. Therefore, the main performance requirements for bearings are low vibration and noise, low friction torque, and good sealing performance.
Servo motor bearings possess excellent dynamic operating performance, perfectly adapting to the complex working conditions of servo systems, including frequent starts and stops, rapid acceleration and deceleration, and instantaneous reversals. The bearings undergo ultra-precision machining of the raceway and structural optimization, resulting in uniform and stable rotational resistance. This effectively reduces torque fluctuations and prevents vibrations and jamming during equipment operation. Under high-speed operation, the bearing has strong resistance to deformation, small vibration amplitude, and low temperature rise. It will not cause operating deviation due to centrifugal force and alternating load, and also has excellent low-speed smoothness. Stable dynamic performance can accurately match the high-precision and high-response control requirements of servo motors, continuously maintain the motion accuracy of equipment, and ensure the smooth and reliable operation of the entire automation system.
Bearings are prone to problems such as accelerated wear, grease aging, and decreased precision after long-term use, making them unsuitable for the continuous operation of servo equipment under long-term, high-load conditions. The servo motor bearings, through precision process optimization, material upgrades, and exclusive lubrication matching, possess excellent long-term stability. They can resist the wear caused by alternating loads, temperature changes, and high-speed friction for a long time, and can maintain precise rotation accuracy and stable operation. This effectively delays performance degradation and ensures long-term high-precision, low-failure, and stable operation of servo equipment.
