B25-224-2RS/P4 High-Speed Servo Motor Bearing

High-speed servo motor bearings are primarily used in FANUC robot servo motors, Siemens servo motors, drilling and tapping machines, or CNC machining centers. Spindle motors are mostly used in drilling and tapping machines or CNC machining centers, connected to the rear end of the spindle via couplings or belts to drive the spindle's high-speed rotation. The motor is required to have very smooth rotation and reliable acceleration capabilities. Through optimized structural design, the motor is miniaturized, and the selection of bearings is particularly critical. Servo motors require bearings with high precision, high speed, flexible rotation, low noise, low friction, and long service life. Our company's bearings greatly meet the application requirements of servo motors.

The rings of high-speed motor bearings are made of high-purity bearing steel, combined with special heat treatment processes, cryogenic treatment processes, and material stabilization techniques, significantly improving the fatigue life of this series of bearings. Spindle motor bearings have a deep groove structure and are used individually, typically one at the front and one at the rear of the motor. The cage is a rolling element-guided nylon (PEEK) cage. The rolling elements are imported ceramic balls, which feature fast heat dissipation, high-temperature resistance, and high-speed operation. Ceramic ball high-speed motor bearings can meet the high-speed requirements of motors, and they also address issues such as bearing temperature rise and noise caused by excessive speed. The service life of ceramic ball high-speed motor bearings is more than three times that of ordinary deep groove ball bearings, and the high-speed performance of the motor is improved by 50%, resulting in significant cost savings and enhanced product reliability and market competitiveness.
