The materials used in different parts of a servo motor bearing vary. We will introduce the materials of each part of the servo motor bearing by component. For the raceway and rolling elements, high carbon chromium steel is generally used. Most bearings use SUJ2 steel, a JIS standard, while large bearings use SUJ3.For applications requiring impact resistance, chromium steel, chromium-molybdenum steel, or nickel-chromium-molybdenum steel can be used, with carburizing and quenching treatment. In addition, there are special materials such as stainless steel, ceramic materials and high-speed steel. The cage is made of materials such as cold-rolled steel, brass plate, stainless steel plate, carbon steel, and synthetic resin. It should be noted that polyamide cages should not be used in environments with temperatures above 120 degrees Celsius or below -40 degrees Celsius, nor are they suitable for vacuum environments. Brass cages should not be used in environments with temperatures exceeding 300 degrees Celsius or in ammonia environments. The most commonly used bearing steel material on the market is GCR15.We have introduced several commonly used materials for servo motor bearings, but the selection of materials should be determined based on the specific application scenario and performance requirements.
Conventional bearings are mostly used in transmission equipment with simple operating conditions and low positioning requirements, and can only meet basic operating needs. Servo motor bearings, with their high precision, low friction, and stable operation, can adapt to complex working conditions such as high-frequency start-stop, rapid reversal, and precise positioning. They are currently widely used in CNC machine tools, automated production lines, industrial robots, 3D printing, semiconductor equipment, and other fields, and are an indispensable core component of high-end precision equipment.
We implement standardized management and control over the entire process of servo motor bearings, focusing on the core requirements of batch consistency and stability. From raw material selection and precision machining to heat treatment and ultra-precision machining, each process undergoes rigorous quality inspection to strictly control key dimensional tolerances and raceway precision. Meanwhile, through batch sampling inspection, torque consistency verification, vibration and noise screening, and simulated working condition durability testing, subtle performance differences can be identified, effectively avoiding problems such as batch deviation and uneven individual performance, ensuring that the precision of each batch of bearings is highly consistent and the performance is stable, meeting the high-quality usage requirements of batch assembly into servo motors.
