# Motion Repeatability Requires Stable Accuracy Over Millions of Cycles

## Motion Repeatability Requires Stable Accuracy Over Millions of Cycles

Robots perform the same motions millions of times. Bearings must maintain accuracy and performance throughout their service life without degradation.

## Repeatability Requirements

- Stable accuracy throughout service life
- No wear on contact surfaces
- Consistent friction torque
- Resistance to fatigue damage

## Solutions

Bearings with high fatigue strength and wear resistance are used. Bearings with optimized contact geometry are employed. It is recommended to use bearings with heat-resistant lubricants.
