The precision of the servo motor bearings complies with the latest standards of ISO 492:2023 and GB/T 307.1-2024, and is divided into five levels: P0, P6, P5, P4 and P2. The precision index gradually tightens as the level increases.P0 and P6 are general industrial-grade precision, mostly used in ordinary transmission equipment, and cannot meet the operating requirements of servo systems.Servo motors generally use P5 precision grade and P4 ultra-precision grade bearings, which can achieve ±0.01° angular deviation, ±0.005mm repeatability, millisecond-level dynamic response, and no crawling phenomenon at low speed.Compared to P6 grade bearings, its friction loss can be reduced by 20% to 30%. It is a core component for precision control in high-end equipment and directly affects the overall performance of the servo system.
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.

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.
