Bearings play a crucial role in industrial robots, serving as a core component to ensure the robot's precision, speed, reliability, and lifespan. They are found throughout the robot's joints and transmission parts, directly affecting its motion performance.

Due to the unique characteristics of industrial robots, extremely high requirements are placed on the bearings used in them:

High Precision: The clearance and rotational accuracy of bearings directly affect the repeatability and trajectory accuracy of the robot. Bearings of P4, P2, or even higher precision grades are typically used.

High Rigidity: When a robot is under load, the deformation of joints and links must be minimal. High bearing rigidity is crucial for maintaining the robot's positioning accuracy and dynamic performance.

Low Friction and High Speed: To pursue efficiency, robot movement speeds are increasing. Bearings need low starting torque and low operating friction to reduce heat generation and energy loss.

Long Lifespan and High Reliability: Industrial robots typically require 24-hour continuous operation with short maintenance windows. Bearings must have extremely high fatigue life and wear resistance.

Compact and Lightweight: To reduce the overall weight of the robot and increase its flexibility, bearings need to adopt a thin-walled design, minimizing size while meeting load-bearing requirements.

Good Sealing: Preventing the ingress of external dust, cutting fluid, and other contaminants, while also preventing internal grease leakage, extends maintenance intervals.

Adjustable preload: Many robot bearings require preload during installation to eliminate clearance and increase stiffness, which requires the bearing design to support precise preload adjustment.
