Higher Standards

Robotics places much stricter demands on bearing performance.

High Precision
High Precision
Robotic motion control requires exact positioning, which demands that bearings possess exceptionally high rotational accuracy and operational stability.
High Rigidity
During high-speed movements and complex sequences of actions, bearings must maintain sufficient rigidity to minimize deformation and tracking errors.

Long Service Life
Robots typically operate continuously over long periods, meaning bearings must deliver excellent fatigue life and long-term reliability.
Low Noise & Low Vibration
Particularly in the fields of collaborative robots (cobots) and humanoid robots, low-noise operation has become a crucial performance metric.
